VMware App Volumes 4 Specialist — Question 46

A 4-node vSAN cluster has a single disk group per host. An administrator wants to increase the capacity of the vSAN datastore by adding a second disk group to each host in the cluster. The newer drives intended for the second disk group are certified and in compliance with VMware Compatibility Guide (VCG). However, the newer devices procured are of a different make and model than the existing disk group composition.
Considering the scenario, which statement is true?

Answer options

• A. This configuration is supported, however performance may vary across disk groups.
• B. The Capacity Tier devices need to be the same make and model as other disk groups.
• C. The Cache Tier devices need to be the same make and model as other disk groups.
• D. This configuration is supported, however a separate controller is mandatory for each disk vendor.

Correct answer: B

Explanation

The correct answer is B because in a vSAN environment, the devices in the Capacity Tier must be identical in make and model to ensure consistent performance and behavior. Other options are incorrect as they either misrepresent vSAN requirements or suggest configurations that are not mandatory.
