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?
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.
did a test, the disk group has been removed but the cache (failed drive) and capacity drives still exist (as it was in the disk group) at the host level. the cache drive was marked as absent vSAN disk with state as dead / error
so i can’t find the correct answer from the options
Correct Answer: D

vSAN interprets the failure of a single flash caching device as a failure of the entire disk group.
When a flash caching device fails, vSAN evaluates the accessibility of the objects on the disk group that contains the cache device, and rebuilds them on another host if possible and the Primary level of failures to tolerate is set to 1 or more.
I think you are right.
