Nutanix Exam NCP-MCI Topic 2 Question 26 Discussion

Actual exam question for Nutanix's NCP-MCI exam

Question #: 26
Topic #: 2

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.

High clock rate CPUs, huh? Sounds like someone's been watching too many tech commercials. I'd go with reducing the vCPUs instead.

I think adding more memory to the VMs could also make a difference.

I agree, reducing the vCPUs seems like a good idea.

Hey, anyone else getting flashbacks to that old 'My CPU is a neural net processor' joke? No? Just me? Alright, moving on...

Adding more memory to the VMs sounds like a no-brainer to me. Those memory utilization numbers aren't exactly inspiring confidence.

Ah, the classic case of resource contention. I'd say reducing the number of VMs on the hosts is the way to go. Spread them out a bit, you know?

I think both suggestions make sense. We should consider making those changes.
