VMware App Volumes Specialist (2021) — Question 8

Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster.
The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.
The current vSAN cluster has the following configuration:
✑ 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM
✑ 1 Disk Group per vSAN node
- 1 x 400 GB
- 4 x 1.8 TB
✑ De-duplication and Compression is enabled.
✑ vSAN Capacity is currently:
- Total: 72 TB
- Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).
As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.
Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)

Answer options

• A. Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.
• B. Update the existing Disk Group, and claim the newly installed drives for each node.
• C. Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.
• D. Install an additional 3 x 1.8 TB SSDs per vSAN node.
• E. Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.

Correct answer: A, C

Explanation

Option A is correct because adding additional SSDs per node increases the storage capacity, thereby doubling usable capacity while maintaining service availability. Option C is also correct as creating a new Disk Group with new drives allows for better management of data and redundancy, which enhances availability. The other options either do not provide sufficient capacity increase or compromise service availability.
