Nutanix NCP-MCA Exam - Topic 5 Question 72 Discussion

Actual exam question for Nutanix's NCP-MCA exam

Question #: 72
Topic #: 5

Refer to the exhibit.

An administrator created the Playbook shown in the exhibit to allow for manual reduction of vCPU count on any selected VM within their environment. During a test run of the play on one of the VMs running in development, the administrator ran into an error that the Playbook cannot be completed against the selected VM.

Here are the details of the affected VM:

VM Name: VM2

vCPU: 4

RAM: 8 GB

OS: Windows 2016

Hypervisor: AHV

What caused this Playbook to fail?

AThis play cannot be executed against a VM on AHV.

BThe VM needs to be powered off before vCPU can be reduced.

CReduction of vCPU cannot be done on a VM with a running snapshot.

DThe play will cause the VM to go below the minimum vCPU.

Show Suggested Answer

Suggested Answer: A

A Category in Nutanix is a grouping of entities (such as VMs, hosts, clusters, etc.) into a key-value pair. Categories are used to organize and manage resources more effectively by tagging them with meaningful identifiers.

Seems odd, but could it really go below the minimum vCPU?

Wait, can you really not change vCPU with a snapshot running?

Definitely not AHV related, that's a common misconception.

I think it's because of the running snapshot issue.

The VM needs to be powered off before vCPU can be reduced.

I recall that reducing vCPU could cause issues if it goes below a certain threshold. Is there a minimum requirement for this VM?

I'm not entirely sure, but I feel like AHV might have specific limitations on vCPU adjustments. Maybe that's why it's failing?

I think I saw a similar question where it mentioned something about snapshots affecting vCPU changes. Is that relevant in this case?

I remember something about needing to power off the VM before making changes to the vCPU count. Could that be the issue here?

I'm a bit confused here. The details about the VM seem pretty straightforward, but I'm not sure which option best explains the failure. I'll need to think this through a bit more carefully.

The question also doesn't say anything about the VM having a running snapshot, so I don't think option C is correct either. I'm leaning towards option D, since the play might be trying to reduce the vCPU below the minimum.

Hmm, I'm not sure about this one. The question doesn't mention anything about the VM needing to be powered off, so I don't think option B is the right answer.

I'm pretty sure this has to do with the hypervisor. The question mentions the VM is running on AHV, so option A seems like the most likely cause of the failure.

I dunno, this whole thing sounds like a case of 'user error' to me. Maybe the admin needs to take a step back and read the manual a little more carefully. Or, you know, just ask Alexa for help. She's always down to troubleshoot some server shenanigans.

Yeah, they should double-check the requirements before running the Playbook.

A, huh? Nah, man, this is an AHV environment. Surely the play should work, right? Unless... the admin forgot to pay their hypervisor subscription. Gotta keep those licenses up to date, folks!

D? Really? Reducing vCPU below the minimum? That's like trying to take the engine out of a car while it's still running. Not gonna end well.

Yeah, trying to reduce vCPU below the minimum is definitely risky. It's like messing with the core functionality of the VM.

Hold up, are we sure it's not C? I mean, a snapshot could definitely throw a wrench in the works here. Gotta make sure that VM is clean before trying to mess with the hardware.

Hmm, I think the correct answer is B. The documentation clearly states that the VM needs to be powered off before reducing vCPU. Trying to do it on a running VM is a big no-no.
