VMware App Volumes Specialist (2021) — Question 21

A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.
The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:
✑ Policy 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding
✑ Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring
✑ Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring
✑ Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring
During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:
✑ Preferred Site - Preferred Site workloads should run on DC1 hosts.
✑ Secondary Site - Secondary Site workloads should run on DC2 hosts.
Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred
Site? (Choose two.)

Answer options

• A. Change the Site Disaster Tolerance setting in Policy 3 to be ג€Dual Site Mirroringג€.
• B. Update vSphere DRS site affinity rules so that Preferred Site workloads should not run on hosts in DC1.
• C. Change the Site Disaster Tolerance setting in Policy 4 to be ג€None - Keep Data on Preferredג€.
• D. Change the FTT setting in Policy 3 to be ג€Erasure Codingג€.
• E. Update vSphere DRS site affinity rules so that Preferred Site workloads must run on hosts in DC2.

Correct answer: C, E

Explanation

Option C is correct because changing the Site Disaster Tolerance setting in Policy 4 to 'None - Keep Data on Preferred' allows workloads to maintain data on their preferred site, ensuring resilience during maintenance. Option E is also correct as it enforces that Preferred Site workloads shift to DC2 hosts, preventing disruptions. The other options either do not align with maintaining service availability or contradict the established policies.
