Nutanix Exam NCP-MCI Topic 2 Question 16 Discussion

Actual exam question for Nutanix's Nutanix Certified Professional - Multicloud Infrastructure v6.5 exam

Question #: 16
Topic #: 2

[All Nutanix Certified Professional - Multicloud Infrastructure v6.5 Questions]

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.)

AReduce the number of vCPUs assigned to VMs.

BAdd more memory to the VMs.

CReduce the number of VMs on the hosts.

DReplace high core count CPUs with high clock rate CPUs.

Show Suggested Answer

Suggested Answer: A, C

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 % can lead to VM performance problems, such as slow response time or application latency. To improve VM performance, the administrator should reduce the number of vCPUs assigned to VMs or reduce the number of VMs on the hosts, so that there is less contention for CPU resources.

I think reducing the number of VMs on the hosts might also help.

Replacing the CPUs might be a bit overkill if the current ones are only at 19% utilization. I'd focus on optimizing the existing resources first.

I agree, let's start by reducing the number of vCPUs assigned to VMs.

Hmm, reducing the number of vCPUs seems like a logical step to improve performance if the CPU utilization is already low. But adding more memory could also help if the VMs are memory-constrained.
