Features Supported by Huawei NetEngine Routers:

Huawei NetEngine routers are designed for various use cases, including WAN, data center interconnect (DCI), and enterprise networking. However, not all models support every advanced feature.

Analysis of Features:

IPsec:Most NetEngine routers support IPsec for secure communication over public networks.

VXLAN:VXLAN support is limited to specific models optimized for data center or cloud environments.

MACsec:MACsec is supported only on certain high-end models for Layer 2 encryption.

FlexE:FlexE is a feature available only on select high-end NetEngine routers designed for 5G transport and DCI.

Conclusion:The statement is FALSE because not all NetEngine routers support all four features (IPsec, VXLAN, MACsec, and FlexE).

Option A:In traditional IP routing, each router in the network must maintain a routing table that contains network-wide routes or at least the routes relevant to its operation. This ensures that packets can be forwarded correctly to their destination.

Option B:Traditional IP routing operates on the principle of the "longest match rule." When a router receives a packet, it examines the destination IP address and matches it against the entries in its routing table. The longest prefix match determines the next hop for the packet.

Option C:Traditional IP networks are inherently connectionless, meaning there is no dedicated path established between the source and destination before data transmission. This lack of connection-oriented mechanisms makes it challenging to guarantee Quality of Service (QoS) across the entire network.

Option D:In traditional IP networks, packets are forwarded using a hop-by-hop mechanism. Each router along the path decapsulates the packet, inspects its headers, and forwards it to the next hop based on its routing table.

In Huawei's SD-WAN solution, the Route Reflector (RR) plays a critical role in distributing routing information across the network. However, the RR does not directly participate in service traffic forwarding. Its primary function is to facilitate efficient route exchange between SD-WAN nodes.

If the RR fails, it may temporarily disrupt the distribution of routing updates, but it will not interrupt service traffic on the entire network. Service traffic continues to flow through established paths until the RR is restored or redundancy mechanisms take effect.

To ensure high availability, the RR is often deployed in redundancy mode, but the claim that its failure will interrupt all service traffic is FALSE .

Redundancy Technologies for Leaf Switches:

To enhance redundancy in data center networks, technologies like stacking and M-LAG (Multi-Chassis Link Aggregation Group) are commonly used.

Huawei CloudEngine 6881 Capabilities:

TheCloudEngine 6881series switchesdo support M-LAG, enabling active-active redundancy between two switches. This ensures high availability and load balancing.

Conclusion:The statement is FALSE because the CloudEngine 6881 supports M-LAG.

MACsec (Media Access Control Security)is a Layer 2 encryption protocol that ensures secure and reliable communication over Ethernet links. Among Huawei'sNetEngine 8000 series routers, the following models support MACsec:

NetEngine 8000 M6:High-performance router with MACsec support for secure WAN connections.

NetEngine 8000 MIC:Modular interface card-based router with MACsec capabilities.

NetEngine 8000 F1A:Fixed configuration router supporting MACsec for secure access links.

TheNetEngine 8000 MIAdoes not support MACsec, making it unsuitable for scenarios requiring Layer 2 encryption.

The transition to all-Ethernet data center networks is driven by several IT transformations. Below is an analysis of each option:

PCIe is replaced : PCIe is a local bus standard used for high-speed device connections within servers. Its replacement does not directly contribute to the shift toward all-Ethernet networks.

Independent deployment : SecoManager can be deployed as a standalone solution for managing security devices across the network.

Integrated deployment with iMaster NCE-IP : SecoManager can integrate with iMaster NCE-IP to provide unified management of IP/MPLS networks and security policies.

Integrated deployment with iMaster NCE-Campus : This is not a supported deployment mode for SecoManager. SecoManager focuses on security management, while iMaster NCE-Campus is tailored for campus network management.

Integrated deployment with iMaster NCE-Fabric : SecoManager can integrate with iMaster NCE-Fabric to manage security policies in cloud data centers and intent-driven networks.

Thus, the correct answer is C , as SecoManager does not support integration with iMaster NCE-Campus.

A Wide Area Network (WAN) is designed to span large geographical areas, such as cities, regions, or even countries. WANs enable long-distance communication and are typically used to connect multiple Local Area Networks (LANs) or Metropolitan Area Networks (MANs). They rely on technologies like MPLS, SD-WAN, and leased lines to provide connectivity over vast distances.

The description provided in the question accurately reflects the characteristics and purpose of a WAN. Therefore, the statement is TRUE .

Dynamic Routing Protocols Overview:

Dynamic routing protocols enable routers to exchange routing information dynamically, allowing them to adapt to changes in the network topology automatically.

Explanation of Each Protocol:

OSPF (Open Shortest Path First):A link-state routing protocol that uses the Dijkstra algorithm to calculate the shortest path to destinations. It is widely used in enterprise networks.

IS-IS (Intermediate System to Intermediate System):Another link-state routing protocol, similar to OSPF, but primarily used in service provider networks.

RIP (Routing Information Protocol):A distance-vector routing protocol that uses hop count as its metric. It is simple but less scalable compared to OSPF and IS-IS.

BGP (Border Gateway Protocol):A path-vector routing protocol used for inter-domain routing (e.g., between autonomous systems). It is the backbone of the Internet.

Conclusion:All four options (OSPF, IS-IS, RIP, and BGP) are dynamic routing protocols.

MPLS (Multiprotocol Label Switching) is a tunneling technology that enables fast, efficient data forwarding based on labels rather than traditional IP routing. It providesconnection-orientedforwarding using label-switched paths (LSPs), ensuring reliableQuality of Service (QoS).

(A) True– MPLS is connection-oriented and enhances QoS by predefining LSPs through traffic engineering.

(B) True– MPLS useslabel switching, eliminating the need for IP lookups at each hop, significantly improving forwarding efficiency.

(C) False– MPLS is not connectionless; rather, it establishes virtual circuits (LSPs) for traffic. It providesend-to-end QoSthrough traffic prioritization.

(D) True– Labels in MPLS can be eithermanually assignedordynamically allocatedusing protocols likeLDP (Label Distribution Protocol)orRSVP-TE.

The Huawei AC6805 is a high-performance wireless access controller designed for large-scale enterprise networks. It supports up to 120 Gbps of forwarding capacity, enabling it to handle high-density Wi-Fi deployments and demanding applications like video streaming and IoT.

The other options (60 Gbps, 40 Gbps, and 100 Gbps) do not match the specifications of the AC6805. While lower-end models in the AC series may have reduced forwarding rates, the AC6805 is specifically designed to deliver exceptional performance for large-scale networks.

Thus, the correct answer is A .

Understanding Multi-GE Switches:

Multi-GE switches support ports with speeds higher than 1 Gbps but lower than 10 Gbps, such as 2.5 Gbps or 5 Gbps. These switches are ideal for high-density Wi-Fi 6 deployments and other bandwidth-intensive applications.

Analysis of Each Series:

S5731-H:This series includes multi-GE ports, making it suitable for high-speed access and aggregation scenarios.

S5736-S:This series does not include multi-GE ports; it primarily supports standard 1 Gbps and 10 Gbps interfaces.

S5732-H:This series includes multi-GE ports and is optimized for enterprise campus and branch networks.

Conclusion:The S5731-H, S6730-H, and S5732-H series switches are multi-GE switches.

Huawei'sSD-WAN multi-fed and selective receiving technologyis not limited to5G links. This technology can be applied to various types of WAN links, including MPLS, Internet, LTE, and 5G, to optimize traffic steering and improve reliability.The multi-fed feature allows multiple links to be used simultaneously, while selective receiving ensures that the best path is chosen for each application based on real-time conditions. This flexibility makes the technology applicable across diverse network environments, not just 5G.

Comprehensive and Detailed in Depth Explanation:An MPLS (Multiprotocol Label Switching) network uses Label Switched Paths (LSPs) to forward packets. However, an LSP is unidirectional , not bidirectional. This means that the path is established in one direction only, from the ingress Label Edge Router (LER) to the egress LER. For bidirectional communication, two separate LSPs are required—one for each direction.

This concept is critical in understanding MPLS architecture, as it ensures efficient packet forwarding based on labels rather than IP addresses. The unidirectional nature of LSPs allows for better traffic engineering and control over data flow in MPLS networks.

Comprehensive and Detailed in Depth Explanation:Huawei IoT APs support multiple methods for integrating IoT modules or functionalities:

Option A: The USB interface allows external IoT modules to be connected to the AP, enabling flexible expansion.

Option B: Some Huawei IoT APs come with built-in IoT chips, providing native support for IoT protocols like RFID and Bluetooth.

Option C: The PCIe interface is another method for integrating IoT modules, offering high-speed connectivity for advanced IoT applications.

Option D: The PoE out port is used to power external devices but does not directly integrate IoT functionality.

These integration methods ensure that Huawei IoT APs can adapt to various IoT use cases, such as asset tracking, environmental monitoring, and smart building management.
