Nutanix Exam NCP-MCI Topic 1 Question 2 Discussion

Actual exam question for Nutanix's NCP-MCI exam
Question #: 2
Topic #: 1
[All NCP-MCI 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.)

Show Suggested Answer Hide 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 could also help improve performance by reducing resource contention.

Adding more memory to the VMs could also be a good option to enhance performance.

You know what, I think we're all on the right track here. Let's go with option B (adding more memory to the VMs) and option D (replacing the high core count CPUs with high clock rate CPUs). That should give us the best shot at improving the VM performance.

I agree, the high CPU ready percentage is concerning. That could be causing a lot of performance issues for the VMs. Adding more memory might help, but I think we need to look at the CPU utilization first.

Hmm, this is an interesting question. The key seems to be finding the bottleneck in the system and addressing it. The CPU ready percentage is quite high, so that's definitely an area to look into.
