Nutanix Nutanix Certifications NCM-5.15 Questions & Answers

• Question 61:

  An administrator is deploying an application using Nutanix Volumes. After configuring the volume group and connecting the guest's iSCSI initiator to the volume group, they begin performance testing. The administrator learns that performance on the virtual disk attached to the iSCSI initiator is far less than that of a virtual disk connected directly to the VM.

  Which situation is causing this condition?

  A. The VM's iSCSI traffic is being routed to the data services IP subnet

  B. The performance test is generating small block random 10

  C. The duster data services IP address is a bottleneck, shared with other iSCSI traffic

  D. Data Locality ensures that VM attached disks are always faster than iSCSI volumes

  Correct Answer: C

• Question 62:

  A systems administrator needs to add more VMs to their Nutanix cluster. Which two actions should the administrator perform to determine if the current cluster could accommodate the new VMs? (Choose two.)

  A. Perform an Inventory with Life Cycle Management.

  B. Determine utilization with Cluster Runway.

  C. Enable Deduplication and Erasure Coding.

  D. Utilize Optimize Resources for VM efficiency.

  Correct Answer: BD

• Question 63:

  An administrator has two clusters: Site A and Site B. Async DR is configured between the clusters as follows: Site A is the Primary Site Site B is the Secondary inactive Site, no VMs running Site A is fully in Production Site B used as Backup/Disaster Recovery

  The customer wants to perform a planned failover between the sites. How should the administrator accomplish this?

  A. Click Activate on the Secondary site within the Data Protection Dashboard

  B. Click Activate on the Secondary site and run deactive NCLI command on Primary site

  C. Choose Migrate on the Secondary site within the Data Protection Dashboard

  D. Choose Migrate on the Primary site within the Data Protection Dashboard

  Correct Answer: D

• Question 64:

  A customer with a four-node RF2 cluster is adding application VMs to their system. After adding these Vms, the Prism dashboard shows 81% storage utilization.

  What is the consequence of running the cluster at 81% storage utilization?

  A. The customer has the ability to add more VMs up to the 100% storage utilization.

  B. There is available capacity in the storage fabric and the cluster is resilient.

  C. Node failure is imminent due to storage utilization.

  D. The cluster is not resilient in the storage fabric

  Correct Answer: D

• Question 65:

  An administrator learns that some security settings in a cluster have been changed. The environment is out of compliance with required policies.

  Which function should be used to revert any settings that have changed from the defaults and prevent further violations?

  A. Cluster Lockdown with strong password enforcement

  B. Advanced Intrusion Detection Environment (AIDE)

  C. Security Configuration Management Automation (SCMA)

  D. Defense Information Systems Agency STIG enforcement

  Correct Answer: C

• Question 66:

  An administrator deploys Exchange on a Nutanix cluster. The administrator creates two containers with RF2 configuration: One container for Exchange One container for the other VMs

  The Exchange VM is experiencing I/O performance issues.

  Which changes to Storage Optimization should be used on the Exchange container to enhance I/O performance?

  A. No data reduction

  B. Post process Deduplication only

  C. Inline compression and EC-X

  D. Inline compression and Deduplication

  Correct Answer: A

• Question 67:

  An administrator needs to deploy an application with a large amount of data connected via Nutanix Volumes.

  Which two actions should the administrator take when designing the Volume Group? (Choose two.)

  A. Use multiple subnets for iSCSI traffic

  B. Enable RSS (Receive Side Scaling)

  C. Enable thick provisioning on the Volume Group(s)

  D. Distribute workload across multiple virtual disks

  Correct Answer: BD

• Question 68:

  An administrator has an existing Nutanix seven-node cluster running at RF2 that must be changed to have the following capabilities: RF3 set for the cluster Performance tier deduplication

  What is the minimum memory needed on the CVMs to allow for these capabilities?

  A. 24GB

  B. 28GB

  C. 32GB

  D. 20GB

  Correct Answer: B

  Controller VMs must be configured with a minimum of 28 GB (20 GB default + 8 GB for the feature) of memory.
