VMware vSphere 6 Beta Foundations — Question 3

A six-node all-flash vSAN cluster has been deployed. Deduplication and compression are enabled. All virtual machines are produced by policies with the rule
Primary level of failures to tolerate set to 1.
How is a vSAN disk group impacted when the cache device belonging to that disk group fails?

Answer options

• A. The capacity devices are automatically reassigned to another disk group in the same host.
• B. The cache device is marked "Absent". A capacity device is automatically promoted to a cache device to minimize downtime.
• C. The cache device is marked "Degraded". The disk group remains online with lower performance levels.
• D. The disk group is taken offline.

Correct answer: A

Explanation

When the cache device fails, the capacity devices in the same disk group are automatically reassigned to another disk group on the same host, which helps maintain availability. The other options are incorrect because marking the cache device as 'Absent' or 'Degraded' does not occur in this scenario, and taking the disk group offline would not be a desirable outcome in a functioning vSAN cluster.
