Question 28

An 8-Node vSAN Stretched Cluster (4+4+1) with a single disk group has a policy with PFTT=1 (mirrored across sites) and SFTT=1/FTM Mirroring (Local

Protection) configured.

The administrator has been alerted that there is a problem with the cluster. The following has been observed:

✑ The vSAN Witness Host is offline.

✑ Two disk failures on two hosts have occurred in the preferred site.

This has resulted in a critical production virtual machine's vmdk becoming inaccessible.

Which step needs to be performed by the administrator to resolve the issue?

    Correct Answer: C

    When a critical production virtual machine's vmdk becomes inaccessible due to the vSAN Witness Host being offline and two disk failures on two hosts in the preferred site, the primary objective is to restore access to ensure data availability. Replacing or restoring access to the existing vSAN Witness Host is essential because it contains the necessary metadata for the impacted objects. Deploying a new vSAN Witness Host would not resolve the issue since it would lack the necessary metadata for the current configuration. Restoring access to the existing Witness Host will enable the cluster to regain quorum and make the objects accessible again.

Discussion
LazylinuxOption: C

C is correct..you need to restore access to witness host

FISJACOption: C

C is Correct. the vSAN Witness Host offline and 2 failures in the Preferred Site. In each of the above failure cases, restoring access to the existing vSAN Witness would make the object accessible. ... Deploying a new vSAN Witness would not because the components would not be present. https://core.vmware.com/resource/vsan-stretched-cluster-guide#sec7373-sub5

cursospcOption: B

But if the witness site is offline, how can you restore access to it? You shouldn't deploy a new witness to continue working with the secondary site?

wooseungminOption: C

Should be recovery

chatGTP select B

gazcorbOption: C

Restoring access (if possible) will give access to the data. Other solutions may result in data inaccessibility.

ChevellOption: C

Restoring access to the witness host will enable the missing components to be accessible. A new witness will not have any metadata for these objects.

Lundu1995Option: C

i go with c. the witness is offline, not crashed. this means the voting for the vmdk is lost which result in inaccessible vmdks. bring the witness back online

khannatOption: C

C is correct as if you deploy a new Witness host it doesn't have witness Metadata for the object(workloads) impacted in disk group failure. the best approach is to restore the access to existing Witness host
