Nutanix NCP-MCI Exam - Topic 3 Question 38 Discussion

Actual exam question for Nutanix's NCP-MCI exam

Question #: 38
Topic #: 3

An administrator is preparing for a firmware upgrade on a host and wants to manually migrate VMs before executing the LCM upgrade. However, one VM is unable to migrate while others migrate successfully.

Which action would fix the issue?

AEnable Acropolis Dynamic Scheduling (ADS) at the cluster level.

BUpdate Link Layer Discovery Protocol (LLDP).

CDisable Agent VM within the VM configuration options.

DConfigure backplane port groups that are assigned to the CVM.

Show Suggested Answer

Suggested Answer: A

If a VM is unable to migrate, the most likely cause is that it is an Agent VM (such as a Nutanix Witness VM or a VM with special dependencies).

Option C (Disable Agent VM) is correct:

Some Agent VMs are configured to prevent migration due to critical roles (e.g., a Witness VM for Metro Availability).

Disabling Agent VM restrictions allows it to migrate before a host enters maintenance mode.

Option A (Enable ADS) is incorrect:

Acropolis Dynamic Scheduling (ADS) helps with VM placement after migration, but it does not force an unmigratable VM to move.

Option B (Update LLDP) is incorrect:

LLDP is used for network discovery, but it does not impact VM migration behavior.

Option D (Configure backplane port groups) is incorrect:

Backplane settings impact CVM communication, not VM migration.

Wait, why would disabling the Agent VM help? That seems odd!

Disabling the Agent VM? Sounds risky!

Definitely not B, LLDP isn't related to VM migration.

A is usually the go-to for migration issues.

Backplane port groups for the CVM? That seems a bit specific; I wonder if that could actually resolve the migration issue.

Disabling the Agent VM sounds familiar, but I can't recall if that would actually help with migration problems.

I think LLDP is more about network discovery, so it might not be the right fix for a migration issue.

I remember something about ADS helping with VM migrations, but I'm not entirely sure if it applies here.

I'm leaning towards option C, disabling the Agent VM, since that could potentially resolve any conflicts or compatibility issues preventing the migration.

Okay, based on the information provided, I think enabling ADS at the cluster level is the most likely solution to fix the issue with the one VM that couldn't migrate.

Hmm, the details about the failed VM migration are a bit unclear. I'll need to think through the possible causes and solutions carefully.
