Exam 5V0-22.23 topic 1 question 19 discussion

When a host fails in a vSAN cluster with vSphere HA enabled, the impacted virtual machines are automatically restarted on alternative hosts in the cluster. vSphere HA will restart only the virtual machines that were running on the failed host, assuming that adequate resources are available on the other hosts in the cluster. The failed virtual machines will not be restarted until alternative hosts have been found, which ensures that the DR policy in the vSAN storage policy is still in place.

The impact to virtual machines running on a failed host using vSANPolicy1, which has a "Failures to Tolerate" setting of 1 failure with RAID-5 (Erasure Coding), will be as follows: B. Each virtual machine will be unavailable for up to 90 minutes while the automatic recovery process completes. With vSANPolicy1 and a "Failures to Tolerate" setting of 1 failure, vSAN will start the resynchronization process automatically to rebuild the data from the failed host. During this time, the virtual machines' data will be reconstructed, and the virtual machines themselves may be temporarily unavailable until the recovery process completes. The duration of the recovery process can vary depending on the amount of data that needs to be rebuilt and the overall cluster load, but up to 90 minutes is a reasonable estimate for recovery time.

D is relevant for policy 2. Considering policy 1 has FTT=1 there is a backup of data available, thus requiring only a restart on a working host

answer correct is A

vSANPolicy 1 FTT = 1 . Can tolerate 1 node failure.

A is answer

"D" answer is not necessarily true. The "vSANPolicy1" has FTT1 redundancy, and there´s enough available space in the vSAN cluster, so correct answer is "A": VMs from the failed host can be restarted with HA on another vSAN host of the cluster, there are no limitations.
