An administrator manages a Nutanix cluster with software data-at-rest encryption enabled using an external KMS. Several VMs are configured with vTPM to support Windows BitLocker encryption.
The administrator needs to perform a disaster recovery operation and restore the VMs on a different cluster. During the recovery, the administrator discovers that the encryption key backup file is unavailable.
What is the expected outcome for the vTPM-enabled VMs?

I’m leaning towards A. BitLocker won’t even ask for the recovery key.

I agree, option D makes sense. Without the keys, it's a dead end.

I think the VMs will fail to start. No backup file means no recovery.

C) is incorrect; the KMS won't help without the backup file.

Wait, are you saying the VMs just won't boot? That's wild!

D) makes sense. Without the backup, those keys are gone.

I think B) could be possible, but it seems unlikely.

A) is definitely the right choice. No recovery key means no start.

If the external KMS is not accessible, I think the VMs would definitely fail to start, which makes me think option D is the right choice.

I feel like the VMs might still start with a new vTPM, but I can't recall if that applies when the key backup is unavailable.

I think I came across a similar question in practice where the VMs wouldn't start without the recovery key. So, I might lean towards option D.

I remember studying about vTPM and how it interacts with BitLocker, but I'm not entirely sure what happens if the key backup is missing.
