VMware App Volumes 4 Specialist — Question 11

A company is using vSAN Data At Rest Encryption. vCenter is placed on a separate management cluster with external storage. The external storage system has suffered from a disk error and the vCenter Server restore from backup has been unsuccessful, due to media errors.
Considering the scenario, which statement is true?

Answer options

• A. All encrypted disk groups become unmounted and remain offline until vCenter Server is back online.
• B. The data within the vSAN datastore is lost, if the hosts are powered off.
• C. The VMs on the vSAN datastore need to be migrated to another datastore as quickly as possible to prevent data loss.
• D. A new vCenter can be deployed using the existing KMS profile and associated with the existing vSAN encrypted clusters.

Correct answer: C

Explanation

The correct answer is C because migrating the VMs off the vSAN datastore is crucial to avoid data loss in this situation. Option A is incorrect as encrypted disk groups do not unmount simply due to vCenter being offline. Option B is misleading since the data is not lost if hosts are powered off; it remains intact unless there are further issues. Option D is also incorrect because while a new vCenter can be deployed, it cannot access the current vSAN encrypted clusters without a proper restore process.
