QUESTION NO: 6
A single capacity disk fails within a vSAN 7.0 U1 cluster running with a "compression-only" configuration enabled. The vSAN administrator must recognize the platform impact that has occurred and take steps to correct it.
Which action should the vSAN administrator take?

A. The hardware failure will impact all disk groups within the ESXi host, so the vSAN administrator will need to manually remove the ESXi node from the vSAN Cluster, replace the failed capacity device, and then re-create the disk group. B. The hardware failure will impact the entire disk group, so the vSAN administrator will need to remove and recreate the disk group following the replacement of the failed storage device. C. The hardware failure will only impact the specific capacity disk, so the vSAN administrator will need to remove and replace the failed capacity device. D. The hardware failure will stop the running workloads, so the vSAN administrator will need to disable the compression-only configuration, replace the failed capacity device, and then re-create the disk group.

Correct Answer: C
