Dell EMC Specialist – Implementation Engineer, ECS — Question 31

You are designing a VxRail Stretched Cluster for a company with two datacenters. The primary datacenter will host all the workloads; the secondary datacenter will be for disaster recovery.
Where should you host the witness virtual appliance?

Answer options

• A. Both datacenters
• B. Secondary datacenter only
• C. Primary datacenter only
• D. Cloud

Correct answer: B

Explanation

The witness virtual appliance should be hosted in the secondary datacenter to ensure that it can effectively provide quorum during failover scenarios. Hosting it in the primary datacenter would not be optimal, as it could lead to a single point of failure. Similarly, using both datacenters or the cloud would complicate the setup without providing the necessary reliability during a disaster recovery event.
