Nutanix Nutanix Certifications NCP-MCI-6.5 Questions & Answers

• Question 161:

  An administrator is commissioning a Nutanix Enterprise Cloud. Once the user VMs have been deployed and are running, the administrator finds that VMs on the same host are able to communicate, but are unable to communicate between hosts.

  What must be changed to enable full inter-VM communications?

  A. Change the spanning-tree port type on the switch.

  B. Change the network the VMs are connected to

  C. Update the switch to specifically allow VLAN 15

  D. The VMs need to have static IP addresses.

  Correct Answer: C

• Question 162:

  Refer to exhibit:

  

  Why has an anomaly been triggered?

  A. Controller reached 2500 IOPS.

  B. Observed IOPS exceed normal values.

  C. Normal Controller behavior has increased.

  D. Observed values do not match predicted values.

  Correct Answer: D

  Explanation: Nutanix anomaly detection is a feature that monitors seasonal trends for time-series data (e.g. CPU usage, memory usage, latency, etc.) and establishes a "band" of expected values based on historical data12. Only values that

  hit outside the "band" will trigger an event / alert1.

  Nutanix leverages a method for determining the bands called `Generalized Extreme Studentized Deviate Test'. A simple way to think about this is similar to a confidence interval where the values are between the lower and upper limits

  established by the algorithm.

  Another web source3 shows an example of how anomaly detection works in Nutanix Prism Central. In the video, you can see that when the observed value of a metric deviates significantly from the predicted value based on historical data, an

  anomaly event is triggered and displayed on a chart.

  Therefore, by comparing the observed values with the predicted values based on historical data, Nutanix anomaly detection can identify abnormal behavior and alert you accordingly.

• Question 163:

  An administrator needs to shut down an AHV cluster to relocate hardware. The administrator upgrades NCC and runs health checks.

  Which steps should the administrator perform next?

  Item instructions: For each procedure, indicate the order in which that procedure must take place to meet the item requirements.

  Hot Area:

  

  Correct Answer:

  

• Question 164:

  Async DR is configured between two sites. A network outage occurs at the primary site.

  Which steps must the administrator perform to bring the VMs back into service at the backup site?

  Item instructions: For each procedure, indicate the order in which that procedure must take place to meet the item requirements.

  Not all procedures are valid. Identify any invalid procedures using the drop-down option.

  Correct Answer:

  

• Question 165:

  What is the proper sequence to perform a one-click upgrade to a Nutanix cluster?

  Item instructions: For each procedure, indicate the order in which that procedure must take place to meet the item requirements.

  Not all procedures are valid. Identify any invalid ures using the drop-down option.

  Hot Area:

  

  Correct Answer:

  

  Step 1 ---> Login into Prism Element.

  Step 2 ---> Select the Gear Icon at top right of the page.

  Step 3 ---> Click Upgrade Software.

  Step 4 ---> Select the component to upgrade.

  Step 5 ---> Click download.

  Step 6 ---> Once the download completes, select upgrade.

  Invalid:1 - Select Prism Central.

  2 - Select user login.

  3 - On left select upgrade Prism Central.

• Question 166:

  What is most likely the cause of this issue?

  A. There is a firewall rule blocking VLAN512 traffic

  B. VLAN512 is a reserved VLAN ID, and not usable for guest VMs.

  C. The VLAN was not created on the upstream switches.

  D. The administrator did not created the VLAN on all hosts

  Correct Answer: C

• Question 167:

  A cluster has RF2. The cluster loses two drives on different nodes in the same storage tier.

  What is the effect on the replicas of the VMs?

  A. Some VM data may be lost

  B. No VMs lose data if the node has two or more SSDs

  C. Some VMs may reboot and gain access to data

  D. No VMs lose data because of RF2

  Correct Answer: A

• Question 168:

  What Nutanix feature provides effective caching optimization In VDI environments?

  A. Remote Protection Group

  B. Local Protection Group

  C. Snap Clones

  D. Shadow Clones

  Correct Answer: D

• Question 169:

  The customer is seeing high memory utilization on a mission critical VM. Users report that the application is unavailable. The guest OS does not support hot add components.

  How should the administrator fix this issue?

  A. Access the CVM on the host that is running the VM: *Open acli *Run a command to increase the amount of RAM assigned to the VM

  B. From the Prism web console: *Go to the VM dashboard *Select the VM from the VMs list *Choose Update *Adjust the amount of memory assigned to the VM

  C. Go to Control Panel in the VM: *Select the Computer Properties *Increase the amount of RAM assigned

  D. During the next maintenance window: *Select the VM from the VMs list *Perform a graceful shutdown

  Correct Answer: D

• Question 170:

  An administrator migrates a VM onto a new Nutanix cluster- After the migration, the administrator observes the following conditions:

  Cluster memory utilization: 64%

  Cluster CPU utilization: 19%

  Cluster storage utilization. 32%

  Average VM CPU utilization: 25%

  Average VM CPU ready%: 24%

  Average VM memory utilization: 60%

  Which two changes should the administrator make to improve VM performance? (Choose two.)

  A. Reduce the number of vCPUs assigned to VMs.

  B. Add more memory to the VMs.

  C. Reduce the number of VMs on the hosts.

  D. Replace high core count CPUs with high clock rate CPUs.

  Correct Answer: CD
