VMware App Volumes 4 Specialist — Question 40

A 3-node All-Flash vSAN cluster has this configuration:
✑ One disk group per host
✑ All disk groups have identical make & model disks of an 800GB NVMe SSD cache and 2x 4TB SAS SSDs each
An administrator has been tasked with expanding storage capacity by adding one additional disk group with this configuration:
✑ 1.6TB SAS SSD cache and 1x 4TB SAS SSDs
Assuming all the disks are compliant with the vSAN HCL, which is true?

Answer options

• A. The additional disk group would not be possible as vSAN would not allow it.
• B. The additional disk group would work and be fully supported by VMware support.
• C. The additional disk group will generate an "˜Advanced vSAN Configuration in sync' health check warning.
• D. The additional disk group would make this cluster an unsupported configuration.

Correct answer: D

Explanation

The correct answer is D because adding a disk group with different cache size violates the uniformity requirement for disk groups in a vSAN cluster. Options A, B, and C are incorrect as they do not address the fundamental compliance issues that arise from the differing specifications of the additional disk group.
