VMware App Volumes (VCP-AM 2019) — Question 10

A single disk in a vSAN disk group suffers from an unrecoverable hardware failure. This causes vSAN to set the health status for all disks in the group to
Permanent disk loss, indicating disk failure.
Assuming all other disks have not suffered from a hardware failure, why would vSAN mark all disks in the group as failed?

Answer options

• A. The vSAN disk management service has failed.
• B. The affected vSphere host is offline.
• C. The key management server is offline.
• D. Deduplication and compression are enabled on the vSAN cluster.

Correct answer: D

Explanation

vSAN marks all disks in the group as failed due to the dependence on deduplication and compression, which requires all disks to be operational. If one disk fails, it affects the entire data integrity and availability, leading vSAN to categorize all disks in the group as permanently lost. The other options do not directly relate to the status of the disks within the group.
