Nutanix NCP-MCI Exam - Topic 1 Question 2 Discussion

Actual exam question for Nutanix's NCP-MCI exam

Question #: 2
Topic #: 1

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.

Wait, 24% CPU ready? That's kinda high, right?

High clock rate CPUs? Sounds like a solid plan!

Definitely add more memory to the VMs.

I feel like replacing CPUs might be overkill; the CPU utilization is pretty low at 19%, so maybe we should focus on memory instead.

I practiced a similar question where reducing the number of VMs helped with performance issues, but I’m not confident if that applies here.

I’m not entirely sure, but I think adding more memory to the VMs might improve performance since their memory utilization is already at 60%.

I remember that high CPU ready times can indicate resource contention, so maybe reducing the number of vCPUs could help?

This is a tough one, but I think I'll start by trying to reduce the number of vCPUs assigned to the VMs. That seems like the most straightforward approach based on the data.

Based on the information provided, I'd say reducing the number of VMs on the hosts and replacing the CPUs with higher clock rates could be good options to try.

I'm a bit confused by the CPU ready percentage. That seems pretty high, so I might consider looking into that as well.

Okay, let's see. The CPU and memory utilization seem a bit high, so I'm thinking either reducing vCPUs or adding more memory could help improve performance.

Hmm, this looks like a tricky one. I'll need to carefully analyze the utilization metrics to determine the best course of action.

This seems like a straightforward problem that can be solved using equivalence partitioning. I'll focus on testing the three key partitions for the vehicle power ranges.

Wait, do I need to select more than one image to enable the Group button? I better double-check the instructions.

I think A and E are the way to go here. The admin needs to be able to manage the CapEx app itself, including security and dimensions, but doesn't need the broader access of a Planning Server admin or other specialized roles.

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.
