VMware App Volumes 4 Specialist — Question 25

A higher level of resiliency has been requested for an existing vSAN Stretched Cluster. A key requirement will be the addition of a third site to protect against a potential double site failure of the two mirrored sites in the stretched cluster.
What solution would meet the resiliency requirement?

Answer options

• A. Replicate to the third site at the VM level using vSphere Replication.
• B. Configure vSAN Stretched Cluster with FTT=2 to replicate to the third site.
• C. Add the third site to the existing vSAN Stretched Cluster.
• D. Replicate to the third site at the vSAN datastore level using Site Recovery Manager.

Correct answer: C

Explanation

The correct answer is C because adding the third site to the existing vSAN Stretched Cluster directly addresses the need for increased resiliency against double site failures. Options A and D involve replication methods that do not inherently increase the cluster's resiliency structure. Option B is incorrect because configuring FTT=2 would not integrate a third site but rather increase the number of copies of data within the existing sites.
