NCP-MCI-6.5 Free Practice Test

An administrator has been notified by a user that a Microsoft SQL Server instance is not performing well.
When reviewing the utilization metrics, the following concerns are noted: Memory consumption has been above 95% for several months
Memory consumption has been spiking to 100% for the last five days Storage latency is 2ms.
When logging into Prism Central, how could the administrator quickly verify if this VM has performance bottlenecks?

1. A. See Capacity Runway.
2. B. Filter VM by Efficiency.
3. C. Update Capacity Configurations.
4. D. Perform Entity Sync

Correct Answer: B
This will allow the administrator to quickly identify VMs that are overprovisioned or underutilized based on their performance metrics. https://www.nutanix.com/support-services/training-certification/certifications/certification- details-nutanix-certified-professional-multicloud-infrastructure-6_5

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.)

1. A. Reduce the number of vCPUs assigned to VMs.
2. B. Add more memory to the VMs.
3. C. Reduce the number of VMs on the hosts.
4. D. Replace high core count CPUs with high clock rate CPUs.

Correct Answer: AC
According to the CPU (%) - VMware Docs web search result2, one of the possible causes of high CPU ready % is over-provisioning vCPUs for a VM or having too many VMs on a host. CPU ready % indicates the percentage of time that the VM was ready, but could not get scheduled to run on the physical CPU. High CPU ready

In Nutanix clusters, which feature ensures VMs can be migrated and restarted on another host in case of failure?

1. A. High Availability
2. B. Protection Domain
3. C. Host Affinity Rules
4. D. Availability Zone

Correct Answer: A

In a default configuration of an AHV cluster, a single node fails. What happens to the running VMs on that node?

1. A. The cluster restarts all VMs in the event of a host failure
2. B. The VMs do a live migration to the master node in the cluster
3. C. The VMs do a live migration to any other node in the cluster
4. D. The cluster attempts to restart VMs on other hosts

Correct Answer: D
Reference: https://portal.nutanix.com/page/documents/details?targetId=Web-Console- Guide-Prismv5_16:Web-Console-Guide-Prism-v5_16

An administrator has an AHV cluster that is comprised of 4 nodes with the following configuration in each node:
CPU:2 each 2.4GHz, 12 core Memory: 256GB
Disk: 6 each 1.92 SSD
A VM with 16 vCPUs and 96GB of RAM is being created on the cluster.
How should the administrator configure the VM to assure optimal performance?

1. A. With an affinity policy
2. B. With memory overcommit
3. C. With 2 vNUMA nodes
4. D. With Flash Mode enabled

Correct Answer: C
The best way to configure the VM for optimal performance is to set it up with 2 vNUMA nodes. This will ensure that the VM is configured to take advantage of the CPU and memory resources available in each node, and it will also ensure that all of the cores are utilized for the best performance. Additionally, the administrator should ensure that the VM has an affinity policy set up so that the vCPUs are evenly distributed across the four nodes. Finally, Flash Mode should be enabled in order to take advantage of the high- performance SSDs that are available in the cluster
