NCS-Core Nutanix Certified Services Core Infrastructure Professional Questions and Answers

An administrator is trying to correct high cluster IOPs and Cluster Controller Latency. Networking is the suspected issue.

Which networking parameters should be configured in the Nutanix cluster?

A systems administrator configures a protection domain replication between two Nutanix clusters. After the first successful replication , the administrator tests DR by clicking activate on the remote cluster.

While VMs are active on the remote cluster, the protection domain is marked as active on both clusters.

What steps are required to return both clusters to their original state?

Refer to the exhibit.

A Microsoft SQL 2016 deployment is shown in the exhibit. The administrator receives user reports that database queries take too long to return.

Which optimization should be made to this configuration to improve performance?

Refer to the exhibit.

An administrator notices a critical alert on the Metro Availability Protection Domain What is causing this alert?

A consultant is performing a Nutanix Cluster installation on Dell XC Core hardware. The consultant decides to use Foundation Portable for Mac to perform the installation. When the consultant arrives onsite, Foundation Portable is unable to locate the new nodes.

Which log should the consultant check to troubleshoot this issue?

Microsegmentation was recently enabled in a Nutanix environment. The administrator wants to leverage Prism Central to create a policy that will block all traffic, regardless of direction, between two groups of VMs identified by their category.

Which policy should be used to meet this requirement?

An administrator receives reports that VDI desktop performance in an 8-nodeNutanix VDI environment is poor. Opening applications takes between 1 and 2 minutes.

When investigating the issue, the following conditions are found:

• Cluster memory utilization: 80%

• Cluster SSD utilization: 70%

• Average VM CPU Wait Time: 11%

•CVM CPU utilization: 75%

Which action should be taken to improve VDI performance?

A consultant successfully installs the Foundation VM on a laptop and needs to ensure the VM can communicate externally.

Which two configuration changes should the consultant make next? (Choose two.)

An administrator is implementing a VDI solution. The workload will be a series of persistent desktops in a dedicated storage container withina four-node cluster. Storage optimizations should be set on the dedicated storage container to give optimal performance including during a node failure event.

Which storage optimizations should the administrator set to meet the requirements?

An organization subscribes to field advisories from the Nutanix support portal. An administrator receives an email about a rare problem that could cause cluster instability and affect the entire AOS cluster. The organization is running Vmware vsphere 6.x on Nutanix.

What action should be taken to resolve this issue?

An administrator needs to initiate a new VDI project within a couple of months. Prism Central reports there are no storage resources to accommodate such workloads.

The administrator sees many powered-off VMs and has the authority to delete test VMs powered off at least for 30 days. Test VMs belong to the Test category.

Using Prism Central, which steps are required to identify the correct VMs tobe deleted?

Asystems administrator needs to add more VMs to their Nutanix cluster.

Which two actions should the administrator perform to determine if the current cluster can accommodate the new VMs? (Choose two.)

Which subnet is reserved for internal connectivity within a Nutanix Cluster?

In a Nutanix cluster, a Protection Domain contains 50 entities that are replicated to a remote Single Node Replication Target.

The current schedule configuration is as follows:

• Repeat every 6 hours

• Local Retention Policy 1

• Remote Retention Policy 8

• Starting time 12 am

At 8 am on Monday, the administrator discovers that a protected VM is corrupted. The latest good state was Sunday 2 pm. The administrator needs to maintain current protection.

Which strategy should the administrator use to meet these requirements?

An administrator needs to configure snapshots for DRscenarios. The databases get refreshed on Friday nights regularly. The search service application re-indexes the new application on Saturday nights regularly. The remaining front-end and middle tier VMs are static but do get minor version updates weekly.

The administrator needs to have 2 weeks of daily snapshots for all the VMs in an app group and 2 weeks application consist local snapshots only on Fridays, Saturdays and Sundays on the same group of VMs.

Which two options should the administrator use to configure snapshots?

An administrator is updating disk firmware using LCM and receives the following message:

“there have been 10 or more cluster services restarts within 15 minutes in the Controller VM”

The message appears as each drive is upgraded.

What is the reason this message isbeing generated?

Refer to the exhibit.

An administrator has an existing cluster and needs to improve performance using AHV Turbo. Which two items are required to achieve even greater performance? (Choose two.)

An administrator deletes a large amount of data from a Volume Group presented to a Linux VM. The administrator notices that the deleted data has not been reclaimed as usable storage.

Whataction should be taken to reclaim the storage capacity?

An alert about RX errors on eth2 on a node is reported in the cluster. The administrator logs in to theCVM in question, checks the ping_* files in the data/logs/syststats folder, and notices intermittent ping loss.

The node in question has the following network configuration:

Which action should be used to troubleshoot without disrupting the VMs running on this node?

An administrator needs to maximize storage potential in a six-node cluster. The container is configured with the following:

• Post-process compression
• Capacity deduplication

What should the administrator configure to increase space savings?

After uploading a hypervisor ISO during the Foundation process, a consultant sees a message that the MD5 sum for the hypervisor is not found in the Whitelist file.

Which step should the consultant take next to resolve this issue?

After deploying an AHV cluster connected to Cisco Nexus 9k switches, unexpected network behavior is observed. The consultant needs to rule out physical network mis-cabling without returning to the datacenter.

Which command from the host should the consultant run?

What reference materials should be provided to the customer during the Knowledge Transfer?

A consultant is imaging a Nutanix cluster with VMware ESXi. Foundation returns an error that the media is not a supported ISO. The consultant checks the whitelist file in Foundation and confirms that the version of the ISO is not listed.

Which three actions should the consultant take to resolve this issue? (Choose three.)

Which Nutanix feature creation is described in the Knowledge Transfer?
