Nutanix Exam NCP-MCI Topic 2 Question 28 Discussion

Actual exam question for Nutanix's NCP-MCI exam

Question #: 28
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.

Yes, increasing memory could definitely help with performance.

I believe adding more memory to the VMs could also be beneficial.

High clock rate CPUs, huh? I wonder if they come with a built-in espresso machine. At least it'll keep the administrator awake during those long migration sessions.

Reducing the number of VMs on the hosts? That's like trying to fit a family of five into a studio apartment. Good luck with that one.

Adding more memory to the VMs seems like a no-brainer. Who doesn't love a little extra RAM? It's like giving your computer a big, juicy steak.

I think we should reduce the number of vCPUs assigned to VMs.

Hmm, 19% CPU utilization? Looks like the administrator has some serious hardware envy going on. Maybe they should just upgrade their CPU and call it a day.
