350-601 Implementing Cisco Data Center Core Technologies (DCCOR) Questions and Answers

One of the benefits of independent resource scaling in Cisco HyperFlex hybrid architecture is the flexible expansion of compute, caching, and capacity. This allows for the addition of resources in the required ratios without being constrained by the limitations of traditional converged infrastructure3.

To configure HSRP on a Nexus 7000 series switch for VLAN 100 and ensure the router is the active master, you would typically use the hsrp command within the VLAN configuration mode, set the priority higher than the default to make it the preferred active router, and use the preempt command to allow the router to take over as the active router if it has a higher priority.

 Option C is the correct configuration to apply a power redundancy policy on a Cisco UCS C-Series Rack Server that supports two power sources. The power redundancy policy determines how the server uses the available power supplies to optimize power usage. The grid option means that the server uses power from both power supplies simultaneously. If one power supply fails, the server continues to operate with the remaining power supply. The other options are not suitable for this requirement. The n+1 option means that the server uses one fewer power supply than the number of power supplies that are installed. If a power supply fails, the server uses the extra power supply. The non-redundant option means that the server uses only one power supply, regardless of the number of power supplies that are installed. If the power supply fails, the server shuts down. The ps-redundant option means that the server uses power from the most efficient power supply. If the power supply fails, the server switches to another power supply. References:

 The QoS policy that controls only vHBA traffic is the Fibre Channel policy. In Cisco UCS, the Fibre Channel policy is specifically designed to manage the quality of service for traffic related to virtual Host Bus Adapters (vHBAs), which are used for Fibre Channel over Ethernet (FCoE) storage networking. This policy ensures that the storage traffic is appropriately prioritized and managed within the system.

References:

• Cisco UCS Manager GUI Configuration Guide, which provides details on configuring QoS policies for vHBA traffic.
• Cisco Data Center Core Technologies (DCCOR) study materials, which cover the concepts of QoS and vHBA configuration in a Cisco data center environment.

 The configuration in Option D is a scheduler configuration for creating backup jobs. It specifies a schedule name, job name, and the command to copy configurations to a server in the operations VRF using TFTP protocol. The time start and repeat options are used to schedule two backup jobs per day.

References := This explanation is based on the principles found in the Cisco Data Center Core Technologies documentation, which details the use of scheduler configurations for backup purposes. For more in-depth information, please refer to the Cisco Data Center Core Technologies source book or the official Cisco documentation at Cisco Data Center Virtualization.

POAP is an automatic provisioning and zero-touch deployment feature that assists device owners in the

initial deployment and configuration of Nexus switches.

The feature works by checking for a local configuration script. If the script has been deleted, the switch has

been reset to factory settings, or this is the first boot-up, the POAP daemon will connect to a preset list of

servers to download an initial configuration file.

To perform this operation, the switch must first obtain an IP address from a local DHCP server. POAP

configuration settings can also be passed through the DHCP response.

Which conditions should be verified, so they need to be TRUE. Like no startup (A) and bootup (B). C means

that it needs to miss a license file and E means it needs to miss an NX-OS image.

Options B and D are the correct components that should be checked when a Cisco Nexus 9000 Series Switch fails to boot using POAP (Power On Auto Provisioning). POAP requires a DHCP server to bootstrap IP information for the switch, and a TFTP server that contains the configuration script and the image file for the switch. The other options are either irrelevant or incorrect for POAP. References:

To meet the requirements of performing a backup and restore of the Cisco Nexus 5000 Series Switch configuration using UDP as the only protocol, the network engineer must follow these steps:

• Perform a startup-config backup to a TFTP server. The startup-config file contains the configuration that is applied when the switch boots up. To backup this file to a TFTP server, the engineer can use the copy startup-config tftp: command, and specify the IP address or hostname of the TFTP server and the destination filename. For example:

switch# copy startup-config tftp: Enter hostname for the tftp server: 10.10.10.10 Enter destination filename: backup-config

• Copy backup-config from the backup server to the running-config file. The running-config file contains the configuration that is currently active on the switch. To restore this file from the backup-config file on the TFTP server, the engineer can use the copy tftp: running-config command, and specify the IP address or hostname of the TFTP server and the source filename. For example:

switch# copy tftp: running-config Enter hostname for the tftp server: 10.10.10.10 Enter source filename: backup-config

These steps will allow the engineer to backup and restore the switch configuration using UDP as the only protocol, as TFTP is a UDP-based protocol. The backup-config file can be used when the current working configuration of the switch gets corrupted, as required by the goal. References :=

Before upgrading the Cisco NX-OS software on a Cisco MDS switch, it is important to perform some preparatory steps to ensure a smooth and successful upgrade process. Two of these steps are:

• Check the impact of the upgrade using the show install all impact command. This command displays the compatibility and impact matrix for the upgrade, which shows the current and target versions of the software, the modules that will be upgraded, the modules that will be reloaded, and the modules that will be powered down. This information helps to plan the upgrade and minimize the disruption to the network.
• Back up the configuration of the switch using the copy running-config startup-config command. This command saves the current running configuration to the startup configuration file, which is stored in the bootflash memory of the switch. This ensures that the configuration is preserved and can be restored in case of any issues during or after the upgrade.

References := The information is supported by the Cisco MDS 9000 NX-OS Software Upgrade and Downgrade Guide, which provides detailed instructions and guidelines for upgrading the software on a Cisco MDS switch

The Bash script is designed to loop through the available namespaces and output all registered interfaces within the Cisco NX-OS Guest Shell. The correct code snippet to complete the script is option C, ifconfig "$ns". This command will display the network configuration for each namespace, allowing the engineer to view all registered interfaces.

References: The use of ifconfig in conjunction with namespace variables is a common practice in network scripting to retrieve interface information. For more detailed information on scripting in Cisco NX-OS, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide.

 The solution that meets the requirements for implementing an automation solution to allow the backup of the configuration of Cisco Nexus series switches to a centralized location is the Guest Shell. The Guest Shell is a Linux-based container that runs on the Cisco Nexus operating system and provides a secure environment for running Python scripts and custom applications. The Guest Shell supports the RPM packaging format, which allows the team-developed custom monitoring scripts to be easily installed and managed. The Guest Shell is isolated from the underlying Cisco Nexus operating system, which means that it has no impact on the operating system if the resource contention occurs. The Guest Shell also allows the use of Python to expand the existing automation framework, such as using the NX-API or the Cisco Nexus Python SDK to interact with the switch configuration and state. References :=

When using VMware vMotion to migrate a Cisco WSA virtual appliance from one physical host to another, it is essential that both physical hosts have access to the same network configurations. This includes the same defined networks to which the interfaces on the virtual appliance are mapped. This requirement ensures that the virtual appliance retains its network connectivity and continues to function correctly after the migration1.

References := For more information on the requirements and process of migrating a Cisco WSA virtual appliance using VMware vMotion, you can refer to the Cisco Secure Email and Web Virtual Appliance Installation Guide1.

 To meet the requirements of configuring a QoS policy on Cisco UCS that includes a no-drop class and enables jumbo frames without fragmentation, a QoS system class must be created with an MTU value of 9216 bytes. This MTU size is large enough to support jumbo frames, which can carry more data than standard frames, reducing the number of frames sent and improving network efficiency. The no-drop class ensures that frames are not dropped, which is crucial for certain types of traffic that require reliable delivery, such as storage traffic.

References: The configuration approach is based on best practices for enabling jumbo frames on Cisco UCS blades, as described in the Cisco documentation1. The MTU size of 9216 bytes is commonly used in data center environments to enable jumbo frames

Cisco CloudCenter is the appropriate orchestration solution for the customer’s requirements. It supports the CI/CD model, which is essential for streamlining operations and optimizing costs. Cisco CloudCenter can integrate with Cisco ACI networking and Cisco UCS servers, providing a unified management platform. It also offers on-premises Kubernetes support and AppDynamics performance monitoring without the need to install local clients on managed products, aligning with the customer’s security requirements. References: Cisco CloudCenter documentation and Cisco Data Center Core Technologies study guide.

 The configuration that meets the requirements for a media server to distribute streaming videos only to requesting clients, without propagating the video feed through shared trees if there are no requests, and supporting automatic discovery and announcement of RP-set information, is Option C. This option likely includes the use of Protocol Independent Multicast (PIM) in sparse mode, which is suitable for environments where multiple routers need to dynamically discover the Rendezvous Point (RP) for multicast groups. The configuration would also involve commands to enable Auto-RP for the automatic announcement and discovery of RPs.

References: The explanation is based on the principles of multicast routing and PIM operation as described in Cisco Data Center Core Technologies documentation. For more detailed information, the “Implementing and Operating Cisco Data Center Core Technologies (DCCOR v1.2)” course material and the Cisco official documentation on multicast routing would be the appropriate references.

 An EPLD (Electronic Programmable Logic Device) upgrade on a Cisco Nexus 9000 Series Switch is used to upgrade the field-programmable gate arrays (FPGAs). FPGAs are integrated circuits that can be configured by a customer or a designer after manufacturing – hence “field-programmable”. They are used in Cisco switches to provide hardware functionalities in all modules, and EPLD image upgrades enhance hardware functionality or resolve known issues1.

• Cisco Nexus 9000 Series FPGA/EPLD Upgrade Release Notes

 In Cisco ACI, integrating with a VMware vSphere environment using a VMware Distributed Virtual Switch (DVS) requires creating a Virtual Machine Manager (VMM) domain association under the Endpoint Groups (EPGs). This allows the ACI fabric to extend its policy model to the virtual environment managed by vSphere. The encapsulation VLAN of the EPG is then assigned from a VLAN pool. To ensure that the VLANs are dynamically allocated and can be managed efficiently, a VLAN pool with dynamic allocation should be used. This setup allows for automated management of VLANs and avoids conflicts or manual errors in VLAN assignment12.

 Option A is the correct action that accomplishes the objective. Setting the pinning max-links value to 8 ensures that all host ports are distributed across all eight configured FEX uplinks, providing optimal bandwidth utilization and redundancy. If an uplink fails, this configuration minimizes disruption by automatically redistributing host ports among the remaining active uplinks. References:

 To implement private VLANs for Cisco UCS 8-Series servers, the primary VLAN is already present, and the secondary VLAN needs to be added to both fabrics. The correct configuration set that accomplishes this task is Option C. This option includes the necessary commands to create the VLAN and set its sharing to secondary, which is required for the configuration of private VLANs in a Cisco UCS environment12.

References: = For detailed steps and configurations, refer to the Cisco documentation on private VLANs and UCS configuration12. It provides comprehensive guidance on setting up private VLANs in the Cisco UCS environment.

 To add a Cisco HyperFlex data platform to the Cisco Intersight management portal, two components are required for Intersight to claim the Cisco HyperFlex data platform: the device claim code and the device serial number. The device claim code is a unique identifier that is generated by the Cisco HyperFlex installer and is used to register the device with Intersight. The device serial number is the serial number of the Cisco HyperFlex controller node and is used to verify the device ownership and entitlement3.

When a Cisco Nexus 9000 series switch encounters a startup configuration corruption, the recovery process involves clearing the current configuration, restarting the device, and then restoring the configuration from a previously saved file. The correct sequence is to first clear the configuration to prevent the corrupted startup configuration from loading upon restart. After restarting the device, the previously saved configuration file should be copied to the running configuration. Finally, to ensure the switch starts with the correct configuration in future restarts, the running configuration should be saved to the startup configuration.

References: The recovery process is detailed in the Cisco community documentation, where it outlines the steps for recovering the configuration in UCS by importing the configuration from a previously saved location

• Setting the RADIUS source interface to be mgmt0 for group RAD1 and VLAN 22 for group RAD2 © ensures that login requests from the console and SSH are sourced from the correct interfaces and reach the appropriate RADIUS server.
• Configuring the authentication login to use group RAD1 for console and group RAD2 for remote access (D) directs the switch to use the specified RADIUS server groups for the respective login methods, aligning with the user’s requirements.

These configurations ensure that management access via console and SSH is authenticated through the designated RADIUS servers as intended. It’s important to apply these settings correctly in the switch’s configuration to achieve the desired access control.

In the context of configuring a physical domain and attaching a VLAN pool to it, the commands “attributes” and “variables” are typically used within the configuration scripts. The “attributes” command is used to define specific attributes for elements within the configuration, such as naming conventions or paths. The “variables” command is used to declare variable elements that can be dynamically assigned or modified.

Cisco CloudCenter is the best product to meet the requirements of the customer who wants to offload some of its order processing to a public cloud environment. Cisco CloudCenter allows the customer to deploy and manage applications in different cloud environments, including public cloud, while ensuring cost optimization and automation. Cisco CloudCenter also integrates with Cisco ACI and Puppet to provide consistent networking and configuration management across hybrid cloud deployments. The other products are not suitable for this scenario. Cisco Intersight is a cloud-based management platform for Cisco UCS and HyperFlex systems, Cisco Workload Optimization Manager is a software solution that automates workload placement and scaling across private and public cloud environments, and Cisco Data Center Network Manager is a network management tool for Cisco Nexus and MDS switches. References:

 The correct configuration for a unified I/O link that supports both LAN and SAN traffic using a single Ethernet transport is to configure the interface as a trunk port. This allows multiple VLANs (for LAN traffic) and VSANs (for SAN traffic) to coexist on the same physical link. The auto qos trust dscp command ensures that the Quality of Service (QoS) markings are preserved, which is essential for maintaining traffic prioritization across the network.

These resources provide comprehensive guidance on configuring and managing Cisco Nexus and MDS switches in a data center environment.

 To configure an application profile using REST API, the engineer needs to first authenticate with the APIC using the POST method to the aaaLogin URI. This will return a token that can be used for subsequent requests. The error message indicates that the token is missing or expired, so the engineer needs to perform the POST to aaaLogin method again before configuring the application profile. References := [Cisco APIC REST API Configuration Guide]

NX-API Sandbox is a utility that allows the engineer to translate traditional Nexus CLI inputs and generate Python code using XML and JSON message formats. It is available on a Nexus 7700 series switch as a web-based tool that can be accessed from a browser. It provides a graphical interface for entering CLI commands and viewing the corresponding Python code and output. It also allows the engineer to execute the Python code directly on the switch or copy it to a script file. References := [Cisco Nexus 7000 Series NX-OS Programmability Guide]

 In the context of Bash scripting for system automation, the killproc command is often used to stop a process. The correct option to complete the script for a Chef Client reload would involve sending a HUP (hang-up) signal to the Chef Client process, which is typically done to cause the process to reload its configuration without stopping the service. The command killproc -p $pidfile $exec --HUP would send the HUP signal to the process identified by the pidfile, which is the expected behavior for a Chef Client reload on a system reset.

References := For a detailed explanation and official documentation, the Cisco Data Center Core Technologies source book or study guide should be consulted, as well as the official Chef documentation which provides information on system and service management commands.

The contract between EPG Client and EPG Web allows TCP communication initiated by the client toward the webserver with TCP destination port 80. This means that the host in EPG Client can establish a connection to the webserver in EPG Web on TCP port 80. However, the contract does not allow the webserver to initiate a connection back to the host on the same port, which is typically used for HTTP traffic.

References: The explanation is based on the understanding of Cisco Application Centric Infrastructure (ACI) contracts, which are used to define the communication between EPGs (Endpoint Groups). For more detailed information, refer to the Cisco Data Center Core Technologies source book and the ACI documentation available on Cisco’s official website.

 A hybrid Cisco HyperFlex storage configuration is the best option for a virtual environment that is not performance-sensitive, but requires high storage capacity and a low cost. A hybrid configuration consists of a mix of solid-state drives (SSDs) and hard disk drives (HDDs) in each node. The SSDs are used for caching and metadata, while the HDDs are used for data storage. This allows for a balance between performance and capacity, as well as a lower cost per gigabyte than an all-flash configuration. A hybrid configuration also provides data deduplication and compression features to optimize storage efficiency and reduce the storage footprint. A hybrid configuration is suitable for general-purpose workloads, such as virtual desktop infrastructure (VDI), databases, and file servers. References :=

User A, having both the default role and Custom-Role-B, will be authorized to configure NTP, SSH, and DPVM. The default role allows configuration of NTP and SSH, while Custom-Role-B specifically permits DPVM configuration and denies TACACS+.

References: For further details, refer to Cisco’s official documentation on Role-Based Access Control (RBAC) in the Cisco MDS 9000 Series Switch configuration guides. These resources explain how to assign roles and permissions for configuring various features on the switch.

Option C is the correct choice. The commands copy sftp://admin@192.168.10.100/backup.cfg bootflash:///backup.cfg vrf management followed by configure replace bootflash:///backup.cfg will copy the backup configuration file from the SFTP server to the switch’s bootflash and then replace the running configuration with the backup file without requiring a restart of the switch. This process is known as configuration replace and is a feature that allows for the replacement of the entire running configuration with a new one provided by the user1.

References: The procedure for performing a configuration replace on Cisco Nexus 9000 Series Switches can be found in the Cisco documentation1. It is important to ensure that the backup configuration file is a valid running configuration file and that the switch has connectivity to the SFTP server through the mgmt0 interface. The configure replace command intelligently calculates the difference between the current running configuration and the user-provided configuration, applying only the necessary changes

Ansible is known for its agentless architecture, which means it does not require a software agent to be installed on the target nodes it manages. This contrasts with tools like Puppet and Chef, which typically require an agent to be installed on each node. Ansible uses SSH or WinRM to communicate with the nodes, making it simpler and more secure as it reduces the attack surface and the overhead of managing agents.

References: Comparison of DevOps tools including Ansible, Puppet, and Chef, as well as Ansible’s official documentation.

The output indicates that port channel 1 is trunking, which means it is configured to be an Inter-Switch Link (ISL). ISLs are used in Fibre Channel networks to connect switches and maintain the fabric topology. The “port mode is F” in the output also confirms that it’s an ISL, as F-ports are used for Fabric (switch) ports connecting to N-ports on another switch or node.

 In a Cisco ACI fabric, when implementing a Virtual Machine Manager (VMM) domain, VLANs can be allocated dynamically or statically within a VLAN pool. To incorporate a static VLAN into a dynamic VLAN pool, the correct approach is to add a static VLAN allocation range to the VLAN pool. This allows for the specific VLAN to be reserved and used consistently for certain applications or services, while still maintaining the flexibility of dynamic allocation for other VLANs within the pool.

A logical configuration backup in Cisco UCS Manager includes the AAA and RBAC settings and is stored in a human-readable format. This backup type is suitable for backing up configurations that need to be easily reviewed and audited.

To prevent data corruption due to cross fabric communication in an FCoE environment, the network engineer must apply the configuration Switch(config)#fcoe fcmap 0e,fc,2a to the Cisco Nexus Unified Switches. This configuration sets the FCoE MAC address prefix (fcmap) to a custom value of 0e,fc,2a, which is different from the default value of 0e,fc,00. The fcmap is used to identify the FCoE traffic and map it to the corresponding Fibre Channel ID (FCID). By using a custom fcmap, the network engineer can avoid the possibility of FCID conflicts or overlaps between different FCoE fabrics, which can cause data corruption or loss. The custom fcmap must be configured on all the switches in the same FCoE fabric, and must be unique across different FCoE fabrics. References :=

The command “ldap-server host 10.10.2.2 enable-ssl” is used to configure AAA authentication on an MDS 9000 switch with an LDAP server located at the IP 10.10.2.2. This command ensures that the data sent to the LDAP server is encrypted using SSL, which is a protocol for securing network communication.

References: For more information, refer to the Cisco Data Center Core Technologies (DCCOR) study guide or source documents, specifically the sections covering AAA authentication configuration and LDAP server integration with MDS 9000 switches.

The logical configuration backup type in Cisco UCS Manager includes all logical configuration settings such as service profiles, VLANs, VSANs, pools, and policies. This backup type is suitable for the engineer’s requirements as it contains all vNIC, vHBA, and service profile template settings. Additionally, the logical configuration backup is in XML format, which allows for validation before import1.

 To allow Layer 2 connectivity between Host 1 in VLAN 100 located in DataCenter 1 and Host 2 in VLAN 200 located in DataCenter 2, the correct OTV VLAN mapping configuration is option C. This configuration involves mapping VLAN 100 to VLAN 200 across the OTV overlay so that hosts in these separate VLANs can communicate as if they were in the same Layer 2 domain. The VLAN mapping is achieved by configuring the OTV edge devices in both data centers to associate the VLANs with each other.

To ensure that the Cisco Nexus 7000 series switches are the primary devices for LACP, the system priority needs to be configured with lower values indicating higher priority. In this case, setting N7K_A with a system priority of 100 and N7K_B with a system priority of 200 ensures that N7K_A has a higher priority and becomes the primary device for LACP. The system priority is used in the LACP system ID which determines the LACP priority; the lower the value, the higher the priority.

References: The configuration guidelines for LACP on Cisco devices can be found in the Cisco documentation, which explains the role of system priority in determining the primary device in an LACP setup1. Additionally, the Cisco Data Center Core Technologies study materials provide detailed information on configuring LACP and vPC domain parameters.

 NX-API is a feature that enables the use of JSON and XML encoding when a Cisco Nexus 7000 series switch is deployed. NX-API is a RESTful API that allows external applications to communicate with the switch using HTTP/HTTPS requests and responses. NX-API supports JSON and XML as the data formats for encoding and decoding the requests and responses. By using NX-API, external applications can access and configure the switch features and functions without using the CLI or SNMP. NX-API also provides a sandbox mode that allows users to test and validate their API calls before applying them to the switch. References :=

Option C meets the security requirements for the Cisco UCS C-Series Server. It disables unencrypted communication by enabling HTTPS, sets the session timeout to 900 seconds (15 minutes), redirects HTTP to HTTPS to divert unencrypted traffic, and changes the SSH port to a nondefault value (2022), which is essential for CLI-based management.

References := For further details on securing Cisco UCS C-Series Servers, refer to the Cisco UCS C-Series Servers Integrated Management Controller CLI Configuration Guide, which provides instructions on configuring service profiles, security settings, and management access.

When downloading a firmware image to a Cisco UCS Fabric Interconnect, especially from a remote location, it is crucial to use a protocol that provides both encryption and authentication to ensure the security and integrity of the file transfer. HTTPS (Hypertext Transfer Protocol Secure) is the protocol that meets these requirements. It is widely used for secure communication over a computer network within a web browser, with encryption provided by Transport Layer Security (TLS), which ensures that the transfer of the firmware image is secure and authenticated1.

• Cisco UCS Manager Firmware Management Guide, which provides detailed instructions on managing firmware through UCS Manager, including downloading firmware images to the Fabric Interconnect

A strict CoPP (Control Plane Policing) policy is designed to manage the traffic flow of control plane packets to protect the control plane of routers and switches from being overwhelmed by unnecessary or malicious traffic. When a ping sweep, which involves sending ICMP echo requests to multiple hosts to identify live devices on a network, is performed on a network connected through a switch with a strict CoPP policy, excess ICMP packets can be dropped to prevent them from consuming excessive resources. References: Cisco Data Center Core Technologies source documents or study guide

To configure a SPAN session on a Cisco Nexus 5600 Series Switch that monitors ingress traffic on interface Ethernet 1/3 without impacting the traffic analyzer on Ethernet 1/5, you would typically use the monitor session command to create a new session, specify the source interface with the source keyword, and the destination interface with the destination keyword. Additionally, you would apply a rate limit to the session to adhere to the traffic budget of 1 Gbps.

On Nexus switches, the equivalent command to save the configuration to NVRAM is ‘copy running-config startup-config’. The ‘write memory’ command is specific to Catalyst switches and is not used on Nexus switches.

 Option D is the correct choice. Configuring the vPC role priority and enabling the peer-gateway feature are recommended practices for enhancing vPC convergence times. The peer-gateway feature allows for local forwarding of packets without the need to cross the vPC peer link, which can significantly reduce convergence times during primary peer device failures and recoveries. This approach ensures that the vPC system can quickly adapt to changes and maintain traffic flow even in the event of a device failure123.

References: For more detailed information and best practices, you can refer to Cisco’s official documentation and community discussions on vPC convergence and failure scenarios

When connecting a Cisco UCS Fabric Interconnect (FI) directly to an external storage array using a Fibre Channel (FC) storage port, it is essential to configure the FI in FC switch mode. This mode allows the FI to manage FC traffic and zoning, which is necessary when bypassing an upstream SAN switch. Additionally, creating the required Virtual Storage Area Network (VSAN) within the SAN cloud is crucial for isolating and managing the traffic between the FI and the storage array. The VSAN provides a unique identifier that enables the direct connection and communication between these devices.

References: The configuration steps for direct attachment of a storage array to a Cisco UCS FI are detailed in Cisco’s official documentation and support forums1. Specifically, the process involves setting the FI in FC switch mode and creating the necessary VSAN for the connection1. These references provide guidance based on Cisco’s recommended practices for such configurations.

 The commands shown in the exhibit configure Unicast Reverse Path Forwarding (uRPF) in loose mode on the interface Ethernet 2/2. The ip verify unicast source reachable-via rx command enables uRPF to check that the source address of a received packet has a route in the routing table and that the packet has been received from a valid interface that aligns with the routing table. This helps prevent IP spoofing by ensuring that packets are received from the expected interface.

References := This explanation is based on the principles of uRPF as described in Cisco’s security configuration guides and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials. For more detailed information, please refer to these resources.

To monitor ingress traffic from SW1 and SW2 port-channel interfaces from SW3, the engineer must implement a configuration that specifies the source interfaces for monitoring and the destination interface where the monitored traffic will be sent. The correct configuration is found in Option D, which includes the commands to create a monitor session, specify the source interfaces as port-channel 1 and port-channel 2 with the ‘rx’ option to indicate ingress traffic, and set the destination interface to Ethernet 1/4 where the traffic can be analyzed. This setup uses a Switched Port Analyzer (SPAN) or Remote SPAN (RSPAN) to capture and forward the traffic for monitoring purposes.

References := The configuration aligns with Cisco’s best practices for setting up SPAN or RSPAN sessions for traffic monitoring as detailed in the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials and Cisco’s official documentation

The statement that is true about the behavior of multiple roles applied to a user on the Cisco MDS 9000 Series Switch is that access to a command takes priority over being denied access to a command. This means that if a user has multiple roles assigned and one of the roles grants access to a command while another role denies access to the same command, the user will be able to execute the command. The access permission overrides the deny permission in case of a conflict. The other statements are not true because:

• Any commands that have conflicting settings between roles are not denied. As explained above, the access permission prevails over the deny permission in case of a conflict.
• The first role assigned does not take precedence over subsequent roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied.
• The last role assigned does not take precedence over previous roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied. References: For more information on how to configure and manage roles on the Cisco MDS 9000 Series Switch, please refer to the following resources:

• Create a user defined role and add the required privileges.
• Assign a role to a user. Comprehensive and Detailed Explanation: = To meet the requirements of adding a new FCoE VLAN to the core switches with restricted read-write access, the network engineer must create a user defined role and assign it to a user. A user defined role is a custom role that can be created to grant specific privileges and permissions to a user, based on the tasks and functions they need to perform. A user defined role can be created using the role command, and then the required privileges can be added using the rule command. For example, to create a role named FCoE-admin and add the privilege to configure FCoE VLANs, the following commands can be used:

role FCoE-admin rule 1 permit read-write feature fcoe rule 2 permit read-write feature vlan

After creating the user defined role, it can be assigned to a user using the username command. For example, to assign the FCoE-admin role to a user named John, the following command can be used:

username John role FCoE-admin

By creating and assigning a user defined role, the network engineer can ensure that the user has the minimum required privileges to perform the FCoE VLAN configuration, without granting them full network-admin access or modifying the existing roles. References :=

To recover the configuration of the Cisco UCS Manager from a full backup available on a backup SCP server, the actions in Option A should be followed. These actions typically involve accessing the Cisco UCS Manager interface, navigating to the backup and restore settings, and initiating a restore operation using the SCP protocol to retrieve the backup file from the SCP server.

References: = For detailed steps and best practices, you can refer to the official Cisco documentation on “Backing Up and Restoring the Configuration” in the Cisco UCS Manager guide1.

 Promiscuous mode (D) allows a virtual machine to observe all traffic on the virtual switch, which is necessary for the virtual machine to receive all frames. VLAN (E) is used to map the frames to a specific Layer 2 network. These settings ensure that the virtual machine receives all traffic for the specified VLAN, fulfilling the requirements stated in the question1.

Cisco NX-OS Data Management Engine (DME) model is a hierarchical representation of the configuration and operational state of the Cisco NX-OS devices. It supports multiple protocols for accessing and manipulating the data, such as NETCONF, RESTCONF, gRPC, and CLI. Among these, NETCONF is the recommended technology for managing a large-scale data center and collecting information from multiple Cisco NX-OS devices using DME model, because it provides a standard, secure, and scalable way of communicating with network devices. References := [Cisco NX-OS Data Management Engine Model]

 To block traffic between a subset of endpoints in an EPG based on specific VM attributes and the rest of the VMs in that EPG, the correct set of actions would involve setting “Allow Microsegmentation” under the EPG VMM Domain Association to “True” and setting “Intra-EPG Isolation” to “Enforced” for both the EPG and the uSeg EPG. This configuration ensures that microsegmentation is allowed and that intra-EPG isolation is enforced, effectively blocking the specified traffic.

To achieve the goal of creating a new user in the local user database on Cisco UCS Fabric Interconnect that can change the vNIC and vHBA profiles and the fan speed and power redundancy profile of UCS Manager, the engineer needs to assign two roles to the user: server-compute and server-profile. The server-compute role allows the user to configure and manage the compute resources, such as servers, service profiles, pools, and policies. The server-profile role allows the user to configure and manage the network resources, such as vNICs, vHBAs, VLANs, VSANs, and LAN and SAN connectivity policies. These two roles provide the user with the necessary permissions to change the configuration inside UCS Manager version 3.1, as required by the goal. References :=

The location where the engineer can look for the latest core dump file after a Cisco MDS 9000 series storage switch has reloaded unexpectedly is /mnt/core. A core dump file is a file that contains the memory state of the kernel at the time of a system failure. The core dump file can help the engineer or the Cisco technical support to analyze the cause of the problem and to fix it. The core dump file is stored in the /mnt/core directory on the switch, and it can be accessed using the CLI command ‘show cores’ or ‘utils core active list’. The other directories (/mnt/pss, /mnt/logs, and /mnt/recovery) do not contain the core dump file, but they may contain other useful information for troubleshooting, such as process state information, log files, and recovery files.

 The command “alert-group Inventory user-def-cmd show logging last 100” is used to configure the Smart Call Home feature to generate an email with the last 100 lines of the log when new hardware is inserted. This command specifies the alert group ‘Inventory’ and the user-defined command to show the last 100 lines of the logging buffer

The correct configuration to capture traffic only from the server with the IP address of 198.19.1.19/24 is option C. This configuration uses an IP access list to match packets from the specific IP address with a subnet mask of 255.255.255.255, which indicates a single host. The monitor session command is then used to apply this access list to a SPAN session, ensuring that only traffic from the specified server is captured.

NETCONF is the ideal solution for this scenario for the following reasons:

• Standards-based: NETCONF is built upon industry-standard protocols (XML, SSH, TLS) ensuring compatibility and adherence to open standards.
• Secure transport: NETCONF mandates secure transport mechanisms like SSH or TLS for communication between the automation software and managed devices, aligning with security requirements.
• Data Format: NETCONF utilizes XML for data encoding and transport, providing a human-readable and machine-parsable format that is easy to work with.
• Remote Device Automation: NETCONF is designed specifically for remote configuration and management of network devices, making it perfect for the task of automating remote device deployments.

 to configure FCoE between the N9K-A switch and the FCF-A Nexus 9000 core switch with the given characteristics, the correct configuration would be the one that enables FCoE NPV mode, binds the interface to a port-channel, and allows only VSAN 20 on the trunk. Based on the provided CLI configurations, the correct answer would be Option D as it configures the switch in NPV mode and allows only VSAN 20

The issue with the implementation is that zones are local to the MDS switch, and name service must be used to activate the connection between E ports. In Cisco MDS switches, zoning is enforced at the switch level. Each switch in a fabric can have a different active zone set or none at all. The name server for each switch only contains information about devices that are logged into that specific switch.

The MAC address that is an HSRP version 2 address is 0000.0C9F.F0C8. HSRP (Hot Standby Router Protocol) is a protocol that provides redundancy and load balancing for IP networks by allowing multiple routers to share a virtual IP address and MAC address. HSRP version 2 supports up to 4096 groups, and uses a different MAC address format than HSRP version 1. The MAC address format for HSRP version 2 is 0000.0C9F.FXXX, where XXX is the hexadecimal value of the group number. For group 200, the hexadecimal value is C8, so the MAC address is 0000.0C9F.F0C8. References :=

 Cisco Fabric Services (CFS) offers a logical scope distribution mode that allows configurations to be distributed within the scope of a VSAN. This mode is suitable for features like NTP, where the configuration database is applicable only within a VSAN. It ensures that changes are contained within the specific VSAN, preventing any impact on other VSANs in the network.

References:

 To reduce disruptions during a major software upgrade on a Cisco Nexus Series switch, technologies like VDC (Virtual Device Contexts) and vPC (Virtual Port Channels) can be implemented. VDC allows for the partitioning of a single physical device into multiple logical devices, which can be managed and operated independently. This means that one VDC can be upgraded while others remain operational, minimizing downtime. vPC enables the linking of two switches to create a single logical switch, providing redundancy and allowing for one switch to be upgraded while the other maintains the network operations1.

 Option D and C are the correct policies that must be configured to meet the requirements. A Maintenance Policy specifies how the changes are applied when a service profile is associated or disassociated with a server or when an updated service profile is applied to a server. A Power Control Policy allows users to select how Cisco UCS Manager should restore power to the servers in a chassis after the chassis loses power. References:

 Since the AAA server is unreachable and TCP communication with the AAA servers is disabled, the network administrator must log in locally using a network-admin role. The upgrade files can then be downloaded from a remote TFTP server, which does not require TCP communication and can operate over UDP, thus bypassing the TCP restriction.

In the ERSPAN configuration provided, Host B is connected to Switch A and is configured as the source of the ERSPAN spanned traffic. This is indicated by the configuration on Switch A, which includes the command monitor session 48 type erspan-source, specifying that it is sending ERSPAN traffic to a destination. The destination IP address for this traffic is set to 10.11.11.2, which corresponds to Host A’s interface VLAN12 IP address. Therefore, Host A, connected to Switch B, is the traffic analyzer, receiving the spanned traffic from Host B.

References := The explanation is based on the standard ERSPAN configuration practices where the source switch is configured with a session type of ‘erspan-source’ and the destination switch with ‘erspan-destination’. This information is typically covered in Cisco’s documentation on ERSPAN configurations and the Cisco Data Center Core Technologies (DCCOR) course materials.

 In the context of configuring an FCoE connection between a Cisco UCS and a Cisco Nexus 9000 Series Switch, changing the transport type to FCoE in the Cisco UCS Manager is essential. This action ensures that the data traffic is encapsulated using FCoE, enabling seamless communication over Ethernet networks while maintaining Fibre Channel protocol characteristics.

References := For more detailed information, you can refer to the Cisco Nexus 5000 Series NX-OS Fibre Channel over Ethernet Configuration Guide1, which provides comprehensive guidelines on configuring FCoE, including the importance of changing the transport type to support FCoE deployment.

The import function is available for all configuration, system configuration, and logical configuration files. You can perform an import while the system is up and running. An import operation modifies information on the management plane only. Some modifications caused by an import operation, such as a change to a vNIC assigned to a server, can cause a server reboot or other operations that disrupt traffic. https://www.cisco.com/en/US/docs/unified_computi ng/ucs/sw/gui/config/guide/141/UCSM_GUI_Configuration_Guide_141_chapter43.html#concept_D789E16C90724AEFB99D565574E45AD5

Two capabilities of the Cisco Network Assurance Engine are that it validates that devices comply with network security policies and that it predicts the impact of changes to the network. The Cisco Network Assurance Engine is a software solution that uses mathematical modeling and verification techniques to continuously analyze the state and configuration of the data center network. It can validate that the network devices are compliant with the intended security policies, such as access control lists, firewall rules, and encryption standards. It can also predict the impact of planned or unplanned changes to the network, such as software upgrades, configuration changes, or device failures, and provide proactive recommendations to avoid or resolve issues. The Cisco Network Assurance Engine helps to ensure that the network is always operating as intended and aligned with the business objectives. References :=

SPAN (Switched Port Analyzer) is a feature that allows network traffic from one or more source ports to be mirrored to a destination port for analysis. When configuring SPAN on a Cisco Nexus 5000 Series switch, two characteristics must be considered:

• A SPAN source port can be monitored in multiple SPAN sessions. This means that the same port can send traffic to different destination ports for different purposes or applications.
• A SPAN source port cannot be a destination SPAN port. This means that a port cannot receive traffic from another port that it is already monitoring. This prevents loops and conflicts in the SPAN configuration.

Enabling the vPC peer gateway feature on the vPC devices allows them to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer. This capability allows both vPC peers to forward traffic and eliminates traffic disruption when one of them goes down, ensuring high availability in network operations.

References: = For more detailed information, you can refer to the Cisco Nexus 9000 Series NX-OS High Availability and Redundancy Guide, which provides guidelines on configuring vPC peer gateway features for enhanced network stability and availability.

Bidirectional PIM is designed for scenarios where there are many sources and receivers that need to communicate with each other, such as in videoconferencing. Unlike traditional PIM sparse mode, which creates both (,G) and (S,G) entries, Bidirectional PIM only allows the (*,G) entry for the shared tree and does not build an (S,G) entry. This approach reduces the number of mroute state entries, conserving resources. Traffic can flow up and down the shared tree in Bidirectional PIM, and there is no RPF check; instead, a Designated Forwarder (DF) is used to prevent loops. References := Multicast Bidirectional PIM - NetworkLessons.com

Ansible is known for its agentless architecture, which means it does not require any software to be installed on the target devices. It can manage the devices using SSH, which is typically available on most Linux servers. This makes it suitable for scenarios where the operations team needs to update configurations across a large number of devices without direct access1.

References := For more information on how Ansible works and its capabilities for network automation, you can refer to the official Ansible documentation and resources available on the Ansible website1. These resources provide detailed guidance on using Ansible for network automation tasks, including configuration updates and management.

 The correct answer is option C. The fabric binding configuration in option C matches the output required for the Cisco MDS 9000 Series Switch. Fabric binding enhances the security of the SAN fabric by allowing only authorized switches to join the fabric. The configuration includes specifying the switch world wide name (swwn), domain ID, and member world wide node name (nwwn) to ensure that only the specified devices can participate in the fabric.

References: For more information on fabric binding and its configuration, you can refer to the Cisco MDS 9000 Series Fabric Switches Configuration Guide and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials.

To add a new VRF (DC DC) that allows communication of network prefixes between PE1 and PE2 using MP-BGP and EVPN, the engineer should choose Option B and Option E. These options likely include the necessary configurations for route distinguishers and route targets that facilitate the import and export of routes between the VRF instances on different PE routers1

 In the context of Cisco Data Center Core Technologies, SPAN (Switched Port Analyzer) is used to monitor network traffic. To configure a SPAN session on a Nexus 5000 series switch, an engineer would need to use specific commands. Option A, “Configure the switchport monitor under interface fc2/2,” is correct as it involves setting up the monitoring port under a specific interface. Option D, “Configure session type fc under monitor session 1,” is also correct as it specifies the type of session being configured for monitoring.

References := The explanation can be corroborated with detailed study from Cisco’s official documentation and resources available on their website or the Cisco Data Center Core Technologies source book.

 Option C is the correct adjacency server configuration to make two OTV edge devices located in the same site bring up the dual-site adjacency. The adjacency server is a logical entity that maintains the control plane information for the OTV overlay network. The adjacency server can be configured in unicast-only mode, which means that the OTV edge devices use unicast packets to exchange control plane information. To enable dual-site adjacency, which means that the OTV edge devices can form adjacencies with devices in the same site as well as devices in different sites, the adjacency server must be configured with the same IP address on both devices in the same site. The other options have incorrect configurations or IP addresses. For example, option A uses different IP addresses for the adjacency server on the same site, option B uses the same IP address for the adjacency server on different sites, and option D uses an invalid IP address for the adjacency server. References:

To monitor all LAN traffic on Fabric A from a blade server, the source should be configured as all uplink Ethernet ports in the test-span monitor session. This configuration allows the engineer to capture all LAN traffic that traverses the uplink Ethernet ports, providing a comprehensive view of the network activity related to Fabric A. By monitoring these ports, the engineer can analyze traffic patterns, detect anomalies, and ensure the proper functioning of the network.

The method that a network engineer must use to upgrade the BIOS firmware of a Cisco UCS standalone C-Series rack-mount server is to use the Cisco host upgrade utility. The Cisco host upgrade utility is a tool that allows the network engineer to upgrade the firmware of various components of the server, such as the BIOS, the CIMC, the RAID controller, and the network adapter. The Cisco host upgrade utility can be downloaded from the Cisco website and run from a bootable USB drive or CD-ROM. The Cisco host upgrade utility provides a graphical user interface that guides the network engineer through the firmware upgrade process, and allows the network engineer to select the firmware versions and the components to be upgraded. References :=

To meet the requirements of securing HSRP communication and supporting more than 300 groups, the commands needed are hsrp version 2 which allows for a greater number of HSRP groups (0-4095) and authenticate md5 key-chain NHRP-KEYS which provides MD5 authentication to secure HSRP updates.

The impact of the EPLD update of the supervisor module on the Cisco MDS 9000 switches is that the redundant supervisor takes over while the EPLD update is in progress and there is no service disruption. EPLD (Electronic Programmable Logic Device) is a firmware component that controls the functionality of various hardware modules on the switch, such as the supervisor, line cards, and fabric modules. The EPLD update is performed to enhance the performance and features of the hardware modules, and to fix any bugs or issues. The EPLD update process requires a reload of the affected module, which can cause a temporary loss of connectivity and traffic. However, if the switch has a redundant supervisor module configured in high availability mode, the EPLD update can be performed without any service disruption. This is because the redundant supervisor takes over the control plane functions while the active supervisor is being updated, and then switches back to the active supervisor when the update is completed. The EPLD update does not affect the data plane traffic, as the line cards and fabric modules continue to forward packets during the update process. References :=

 Option D is the correct configuration to enable the Cisco UCS Manager to manage a Cisco UCS C-Series server by using a single cable for management and data traffic. The commands enter the server scope, then the cimc scope, then the mgmt-conn scope with the sideband option, which enables the management connection through the sideband interface. Then, the mgmt-conn-state is set to enabled and the changes are committed to the buffer. References:

 To make a capture task persistent after a reboot, the command sequence in Option C should be used. This typically involves enabling the service to start at boot time using systemctl enable and then starting the service with systemctl start. This ensures that the capture task will automatically resume after the system is rebooted4

Cisco UCS Manager supports various types of authentication mechanisms for enhanced security. Option A (local) refers to the use of locally stored user credentials within the UCS Manager for authentication. Option B (LDAP) indicates that UCS Manager can integrate with LDAP (Lightweight Directory Access Protocol) directories for user authentication, allowing centralized management of user credentials. References: Cisco Data Center Core Technologies source documents or study guide

Option A is the correct command sequence to configure HTTPS secure management for Cisco UCS Manager using a key ring named kr2016 and a key size of 1024 bits. The other options have incorrect commands or syntax errors. For example, option B uses the wrong command to set the modulus size, option C uses the wrong command to create the key ring, and option D uses the wrong command to name the key ring. References:

 The device-alias confirm-commit command is used in Cisco MDS 9000 Series Switches to ensure that changes made to device aliases are confirmed before being committed to the database. This command prompts the user for confirmation and displays the pending changes explicitly on the console, which aligns with the requirements stated in the question.

References: For more detailed information, you would typically refer to the Cisco Data Center Core Technologies study guide or the official Cisco documentation for the MDS 9000 Series.

To monitor and export traffic to a Network Analyzer, particularly ingress traffic from Host-A and all traffic for VLAN 20 from Host-B, the engineer must implement a configuration that captures the specified traffic and directs it to the Network Analyzer tool. The correct configuration will depend on the capabilities of the network devices in use and the specifics of the Network Analyzer’s requirements.

 The configuration must include setting up a SPAN (Switched Port Analyzer) or RSPAN (Remote SPAN) session that mirrors the desired traffic to a port connected to the Network Analyzer. This would involve specifying the source interfaces or VLANs and the destination port for the mirrored traffic. Additionally, the configuration should ensure that the Network Analyzer is capable of receiving and processing the mirrored traffic, which may require additional settings on the Network Analyzer itself.

Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Public cloud services are offered over the internet and are available to anyone who wants to purchase or use them. They are ideal for an engineer with a small budget and limited technical knowledge because they provide a cost-effective, scalable infrastructure that can grow with customer demand2.

The Peer Gateway feature on Cisco Nexus switches is designed to address the exact scenario described. When enabled, it allows the vPC peer switches to forward traffic based on the SVI MAC address, even if it is not the HSRP MAC address. This is particularly useful in cases where end devices do not use the HSRP virtual MAC address for the gateway and instead use the physical MAC address of one of the HSRP routers1. By using the Peer Gateway feature, both N9K_1 and N9K_2 will be able to forward traffic for VLAN 23, ensuring that the packets are not dropped due to the vPC loop prevention mechanism123.

References: = This information is supported by Cisco’s documentation on Nexus 5500 Platform Layer 3 and vPC Operations, which explains the use of the peer-gateway command to allow Layer 3 forwarding in scenarios where the destination MAC of the incoming packet is the MAC of its vPC peer switch1. Additionally, discussions in the Cisco Community confirm the necessity of this feature when certain devices on the network do not properly send traffic to the MAC address specified in the ARP234

 A community cloud Infrastructure as a Service (IaaS) deployment model is suitable for several companies that need to operate the same application environment and integrate it with third-party protocols. It allows the development team to have control over the infrastructure, including the operating system, Python interpreter, and libraries

Option A is the correct configuration to meet the requirements of configuring system logging on the MDS switch. The commands set the console logging level to 5, which corresponds to the severity level of “warning” and above, and set the exec-timeout to 300 seconds, which means that the users will be logged out of the console after 5 minutes of inactivity. The other options are either incorrect or incomplete for the task. References:

To SPAN traffic in both directions from a vNIC on a VM deployed on a Cisco UCS blade server to a packet analyzer connected to UCS-A slot 2 port 12, commands A and D are required. Command A sets the direction of traffic monitoring to both receive and transmit directions, while command D activates the Ethernet traffic monitoring session. The other commands are not needed or incorrect for this configuration. Command B uses the wrong syntax for creating the destination interface, command C uses the wrong keyword for setting the direction, and command E uses the wrong syntax for creating the Ethernet traffic monitoring session. References:

The attribute that must be selected to implement microsegmentation of endpoints within the same IP subnet using a network-based attribute that allows IP subnet independence is the Tag attribute. The Tag attribute is a user-defined attribute that can be assigned to endpoints based on any criteria, such as location, function, or security level. The Tag attribute can be used to create microsegmentation policies in ACI, which define the rules for communication between endpoints within the same or different bridge domains. The Tag attribute enables IP subnet independence, which means that the microsegmentation policies are not tied to the IP subnet of the endpoints, and can be applied across different subnets or even different fabrics. The Tag attribute also simplifies the management and scalability of microsegmentation policies, as it does not require the use of IP addresses or MAC addresses to identify endpoints. References :=

• Cisco Application Centric Infrastructure Fundamentals, Chapter: Endpoint Groups and Microsegmentation, Section: Microsegmentation Using Tags

 Option C is the correct attribute to use to assign the servers to different microsegments based on their VM names. By doing this, IT security can enforce policies that isolate production from development database servers existing in the same EPG and IP subnet. This can be achieved by using the microsegmentation feature of Cisco ACI, which allows granular control over the communication between endpoints within an EPG. References:

 Configuring an ERSPAN session between N5K-1 and N5K-2 is the appropriate action to accomplish the goal of collecting traffic, including payload, for further investigation. ERSPAN will mirror the traffic from the source to the destination over an IP network, allowing the network engineer to capture and analyze the traffic at the headquarters.

 Changing the boot order during setup and applying new requirements multiple times can be achieved by setting the boot configuration directly through the BIOS. This allows the engineer to modify the boot order as needed, separate from the configured boot order in Cisco IMC. References: The DCCOR course discusses server boot order configuration and the use of BIOS settings for such purposes.

 In a VXLAN data center fabric, inter-VNI communication requires mapping Layer 2 (L2) VLANs to their respective L2 VNIs and associating them with the correct Layer 3 (L3) VNI that corresponds to the VRF. In this case, VLAN 100 is mapped to L2 VNI 2020, and for inter-VNI routing to occur, it must be associated with an L3 VNI that corresponds to the VRF, which is Test_Telco_VRF to L3 VNI 1010. References: For more detailed information, you can refer to the Cisco Programmable Fabric with VXLAN BGP EVPN Configuration Guide1 and the Data Center VXLAN EVPN guide

On a Cisco Nexus 7700 Series switch, secured MAC addresses can be removed by either manually deleting the address from the configuration or when the address ages out, which is determined by the age limit set for the interface. The other options do not apply to the deletion of secured MAC addresses.

Option B is the correct answer because it meets both requirements stated in the question. The configuration permits SSH connectivity from a jump host with an IP address of 10.10.10.10/24 and allows all switches to connect via SSH to other devices from the subnet of 10.20.20.0/24.

In this option, the access list acl-1 is configured to permit TCP traffic from host 10.10.10.10/32 (the jump host) on any port, and access list acl-2 is configured to permit TCP traffic from subnet 10.20.20.0/24 on any port.

The ‘line vty’ configuration applies these access lists for inbound (in) and outbound (out) SSH sessions respectively, ensuring that only the specified source IP addresses are allowed for remote SSH management connectivity1.

The DHCP snooping feature acts as a firewall between untrusted hosts and trusted DHCP servers. It validates DHCP messages received from untrusted sources and filters out invalid messages. To implement this on a Cisco Nexus 7000 Series Switch for VLAN 10, you would enable DHCP snooping for that VLAN and then configure the specific interface connected to the legitimate DHCP servers to be trusted. This ensures that DHCP responses from the legitimate servers are allowed, while responses from any other servers are blocked.

Option D is the recommended method to configure the SAN boot when the storage system maps the source WWPN to a unique LUN. This method creates a SAN boot policy in which every initiator is mapped to a different target LUN, which ensures that each server boots from its own LUN and avoids any conflicts or errors. The other options are either incorrect or incomplete for the task. References:

 To meet the requirements of using the secondary interface and then falling back to the primary interface when it becomes available again, the engineer should enable the Uplink failover option in the vNIC properties of the Cisco UCS Cisco Integrated Management Controller (CIMC) network adapter for a standalone Cisco C-Series server. The Uplink failover option allows the vNIC to switch to the secondary interface in case of a failure in the primary interface, and then switch back to the primary interface when it recovers. The Uplink failover option also allows the engineer to configure the Fallback Timeout value, which determines how long the vNIC waits before switching back to the primary interface. In this case, the Fallback Timeout value is set to 600 seconds, which means the vNIC will wait for 10 minutes before falling back to the primary interface. References :=

 Enabling the DHCP relay agent on a switch allows it to forward DHCP BOOTREQUEST packets from clients to a DHCP server, even if they are not on the same physical subnet. This is crucial for clients to obtain an IP address and other network configuration parameters from a DHCP server that is not locally present on the subnet.

To deploy a Cisco UCS C-Series Server with a single VIC 1455 integrated into a Cisco UCS Manager cluster without fabric extenders, the system should be reset to factory default settings using Cisco IMC. After the reset, VIC ports 1 and 3 should be attached to the Fabric Interconnects. This process ensures that the server is recognized by the UCS Manager and can be managed accordingly. The VIC 1455 supports multiple Ethernet and Fiber Channel over Ethernet speeds, making it suitable for direct connection to Fabric Interconnects1.

The virtual-service resize command (D) is used to modify the resource allocation for a Linux container on a Cisco Nexus Series Switch1. This command allows the administrator to specify the amount of CPU and memory allocated to the container, ensuring it has the necessary resources to run successfully. In this case, the command would be used to allocate 10 percent of the CPU and 1024 MB of RAM to the container1.

References: The usage of the virtual-service resize command for managing resources in a Linux container can be found in the Cisco Nexus 9000 Series NX-OS Programmability Guide1.

During the infrastructure firmware upgrade stage using the Auto Install feature, the I/O module is upgraded. The infrastructure firmware upgrade includes updates to the fabric interconnects and I/O modules, which are essential components of the UCS B-Series chassis network connectivity.

To monitor traffic between leaf switches in a Cisco ACI network and support filtering traffic from a Bridge Domain or VRF, the configuration must allow for specifying the traffic of interest based on tenant, application, and EPG. Option C, filter tenant t1 application app1 epg epg1, meets these requirements by defining a filter that targets traffic from a specific EPG within an application profile in the tenant ‘t1’. This filter can be applied to the monitoring session to capture the relevant traffic.

References := For detailed procedures on implementing monitoring sessions in Cisco ACI, refer to the Cisco Data Center Core Technologies documentation, particularly sections covering ACI traffic monitoring and filtering.

To schedule the firmware upgrade of the Red1 and Red2 leaf switches with the requirements of minimal upgrade time, no service impact, and parallel upgrade, SchedulerPolicy1 and SchedulerPolicy2 with a one-time window trigger that has maximum concurrent nodes 2 should be used. This allows both Red1 and Red2 to upgrade simultaneously within the same maintenance window, thus minimizing the time and avoiding any service disruption.
