PowerCLI is a command-line interface for managing VMware vSphere, vSAN and other VMware products. RVC is the Ruby vSphere Console which is an interactive command-line tool for managing vSphere, vSAN, and other VMware products. Using PowerCLI and RVC, you can run commands to identify unassociated objects and take corrective action. For example, you can use PowerCLI to list all vSAN objects and RVC to perform a check on the objects to see if they are unassociated.

This is because vSAN maintains a copy of the object on each host that is a member of the vSAN cluster. When a host enters maintenance mode, the object's replica is moved to another host in the cluster. If another host in the cluster fails during this time, it's possible that the updated replica of an object may be lost. However, vSAN will still use the stale replica of the object on the host that exited maintenance mode to service read requests, and will update the stale replica with the latest writes from the remaining host after the host exits maintenance mode.

It is important to note that this scenario assumes that the host failure is a permanent failure and that vSAN does not have any additional data protection methods enabled such as RAID-5, RAID-6, or Erasure Coding.

The correct answer is D. The latest writes from Host-2 are applied to the stale components of Host-1 once the host exits maintenance mode. This is because vSAN utilizes a "write-order fidelity" mechanism which ensures that any writes that were committed to the other hosts in the cluster before Host-1 entered maintenance mode are applied to the stale components of Host-1 as soon as the host exits maintenance mode.
