Questions 14

An administrator has a 4-node vSAN cluster, and all virtual machine storage policies are configured as RAID-1 FTT-1. The administrator puts Host-1 in maintenance mode using "Ensure Accessibility".

During this time, Host-2, which is holding the updated object replica, fails permanently. A few moments later, Host-1 exits maintenance mode.

What happens to the writes that were committed on Host-2 after Host-1 enters this mode?

Options:

A.

Any writes to Host-2 that occurred after Host-1 entered maintenance mode are lost.

B.

The latest writes are retrieved from backups.

C.

The latest writes were also written on a third host and are applied to the stale components of Host-1 once the host exits maintenance mode.

D.

The latest writes from Host-2 are applied to the stale components of Host-1 once the host exits maintenance mode.
