Question 19

An administrator is responsible for managing a five-node vSAN cluster. The vSAN Cluster is configured with both vSphere High Availability (HA) and vSphere Distributed Resource Scheduler (DRS). The vSAN Cluster is currently hosting 150 virtual machines that have consumed 60% of the usable capacity.

Each virtual machine belongs to one of the following vSAN Storage Policies: vSANPolicy1:

Site Disaster Tolerance: None -

Failures to Tolerate: 1 failure - RAID-5 (Erasure Coding)

vSANPolicy2:

Site Disaster Tolerance: None -

Failures to Tolerate: No data redundancy

Following an unplanned power event within the data center, the administrator has been alerted to the fact that one host has permanently failed.

What will be the impact to any virtual machine that was running on the failed host using vSANPolicy1?

    Correct Answer: A

    Each virtual machine with vSANPolicy1, which has a Failures to Tolerate (FTT) of 1 with RAID-5 (Erasure Coding), can tolerate a single host failure. As long as vSphere High Availability (HA) and Distributed Resource Scheduler (DRS) are configured, vSphere HA will restart the affected virtual machines on the remaining hosts in the cluster, provided there are sufficient resources available. This ensures minimal downtime for the virtual machines, making option A the correct answer.

Discussion
libraboysgOption: A

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

VCIXOption: A

A is answer

goatbernardOption: A

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.

Ansari678Option: B

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.

ieee13940Option: A

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

JoaquinnnOption: A

"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.

answer correct is A
