VMware App Volumes 4 Specialist — Question 38

A vSAN disk group contains one cache drive and four capacity drives. A drive that belongs to this disk group has failed. The entire disk group containing the failed drive is offline.
What are two possible reasons the entire disk group is offline? (Choose two.)

Answer options

• A. Deduplication and compression is enabled on the cluster.
• B. RAID-5/6 (Erase Coding) is one of the failure tolerance methods in use.
• C. The failed drive is configured as a cache drive for the disk group.
• D. Data-at-rest encryption is enabled for the disk group.
• E. Two capacity drives in the disk group are offline.

Correct answer: C, E

Explanation

The correct answer is C because if the cache drive fails, the entire disk group becomes offline since the cache drive is critical for performance and data operations. E is also correct as having two capacity drives offline means there aren't enough drives to sustain the disk group's operations. The other options do not directly cause the entire disk group to go offline.
