Discuss Nutanix NCP-MCI Exam Topic 1 Question 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.

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?

Rosenda 11 months ago

High clock rate CPUs? Sounds like a solid plan!

Malcom 11 months ago

Not sure about reducing VMs, that seems risky.

Erinn 11 months ago

I think reducing vCPUs could help too.

Lashawnda 11 months ago

Definitely add more memory to the VMs.

Phung 11 months ago

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

Clay 12 months ago

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

Roosevelt 12 months ago

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%.

Kiley 1 year ago

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

Devora 1 year ago

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.

Yolando 1 year ago

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.

Kent 1 year ago

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

Adelle 1 year ago

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.

Tegan 1 year ago

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

Victor 1 year ago

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.

Hyman 1 year ago

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

Rosenda 1 year ago

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.

James 2 years ago

I think reducing the number of VMs on the hosts could also help improve performance by reducing resource contention.

Marge 2 years ago

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

Veronika 2 years ago

I agree with that. It can help improve VM performance by optimizing resource allocation.

Naomi 2 years ago

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

Mari 2 years ago

Yes, increasing memory can definitely improve performance.

Shayne 2 years ago

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

Alyce 2 years ago

I agree, that could help improve VM performance.

Gussie 2 years ago

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

Lacresha 2 years ago

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.

Nadine 3 years ago

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.

Adding more memory to the VMs might also be a good idea.

Agreed. That should help with the high CPU ready percentage.

A) Reduce the number of vCPUs assigned to VMs.

Elin 3 years ago

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.
