VMware App Volumes 4 Specialist — Question 21

An architect has been asked to plan the impact of a storage policy change to one of the production All-Flash based vSAN datastores. The change will reduce the failures to tolerate value from 2 to 1 for objects with a RAID-1 (Mirroring) layout in the existing policy. This change will be applied to multiple VMs.
Which statement is correct in this scenario?

Answer options

• A. FTT-2 requires another change to apply a RAID-6 configuration.
• B. The policy will need to be recreated and applied with an additional tag.
• C. There will be no objects rebuilt that impact performance.
• D. There will be an object rebuild impact on performance.

Correct answer: D

Explanation

The correct answer is D because reducing the failures to tolerate from 2 to 1 will result in a rebuild of the objects, which can negatively impact performance. Options A and B are incorrect as they discuss unnecessary changes or requirements that do not pertain to the scenario described. Option C is also incorrect since the change in the failure tolerance does indeed lead to object rebuilding.
