Question 42

Refer to the exhibit.

An administrator is trying to put a node into maintenance mode but receives the message shown in the exhibit.

What is a potential reason for this dialog?

    Correct Answer: A

    The screenshot indicates that the VM is not live migratable. A probable reason for this is that the LinuxVM1 uses vDisks stored in an RF1 DataStore. VMs with RF1 (Replication Factor 1) vDisks do not support live migration due to their lack of redundancy, which requires them to be powered off during host maintenance or upgrades.

Discussion
Hotwired34Option: C

So this one is pretty tricky. I think it's the right answer, since none of the other options are viable. While Virtual GPUs are supported for live migrations, it's best effort and will not work if there's not enough GPU resources in the destination https://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-vpc_2023_3:mul-vgpu-live-migrate-pc-c.html

"While Virtual GPUs are supported for live migrations" eliminates C as a possible correct answer. "It will not work if there's not enough GPU resources" isn't any more compelling than "it will not work if there's not enough memory in the destination." Neither one flags a VM is not live migrateable. Definitely A, and the other comment's link to RF1 limitations confirms it.

sozeOption: A

A is the correct answer {If you want maintenance operations like upgrades and failure handling to be as efficient as possible, you need the ability to migrate your VMs. With AHV, you can live-migrate VMs with vGPU assignments.} https://portal.nutanix.com/page/documents/solutions/details?targetId=TN-2038-AHV:vgpu.html

MikeInITOption: A

For sure the answer is A. This is listed as a feature limitation of RF1 vDisks: https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e000000LUKeCAO

tdog2Option: A

I believe the answer is A. VMs with RF1 vDisks are required to shutdown and restart when the relevant node/cvm go into maintenance or upgrade.

but it isn't shown here if the storage is RF1 or not ??

Zippy12

It's because being on an RF1 datastore is the only of those four options that would generate this message.

headcaseOption: A

correct answer appears to be A. "What is a potential reason for this dialog?" is the key question here and if C said "LinuxVM1 uses a virtual GPU *AND is trying to migrate when no GPUs are available on another host." then that would be correct. But it doesn't say that.
