VMware App Volumes Specialist (2021) — Question 88

Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to increase the cache size and overall capacity of the solution to support an unexpected change in the workload profile and increase the overall performance of the solution.

The current vSAN cluster has the following configuration:

• 6 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM
• 2 Disk Groups per vSAN node (2 x 400 GB, 6 x 3.84 TB)
• De-duplication and Compression is enabled.
• Encryption is enabled.
• vSAN Total Capacity is: ~112 TB RAID6/FTT=2 (80% utilized)

Following the administrator's recommendations, the service owner agrees to purchase 12 x 800 GB SSDs and 36 x 3.84 TB SSDs to upgrade the vSAN but would like to ensure that during the upgrade the availability of the workloads are not affected.

Which three actions should the administrator take to meet this requirement? (Choose three.)

Answer options

• A. Remove the old Disk Groups, and create a new Disk Group using all remaining cache and capacity devices.
• B. Migrate all existing workloads to the new Disk Group(s).
• C. Put each vSAN node into maintenance mode using the Ensure Accessibility option.
• D. Remove the old Disk Groups, and claim the original capacity drives equally across the remaining Disk Groups.
• E. Create two new Disk Groups (each with 1 x 800 GB, 3 x 3.84 TB per node) in the vSAN Cluster using the new storage devices.
• F. Create one new Disk Group (with 1 x 800 GB, 3 x 3.84 TB per node) on the vSAN Cluster using the new storage devices.

Correct answer: C, E, F

Explanation

The correct answer includes actions that maintain workload accessibility during the upgrade. By putting the vSAN nodes into maintenance mode with 'Ensure Accessibility', the administrator can safeguard workloads. Creating new Disk Groups with the new storage devices ensures that the system can handle the increased capacity without disrupting existing workloads. The other options either disrupt the current setup or do not adequately ensure workload availability.
