VMware Carbon Black Cloud Enterprise EDR Specialist — Question 38

All of the virtual machines running on a hybrid vSAN datastore have this storage policy assigned:
Failures to Tolerate (FTT) rule is set to "2 Failures - RAID-1 (Mirroring)"
The vSAN administrator needs to reduce the amount of vSAN datastore capacity the virtual machines will consume.
Which action should the vSAN administrator take to meet this goal?

Answer options

• A. Modify the FTT rule to "2 Failures - RAID-5 (Erasure Coding)"
• B. Add the "Flash read cache reservation" rule to the storage policy, and set to 0%
• C. Disable Operations reserve and Host rebuild reserve and click "Apply"
• D. Change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs

Correct answer: D

Explanation

The correct answer is D because reducing the FTT from '2 Failures' to '1 Failure' decreases the data redundancy, thus lowering the capacity consumed by the virtual machines. Option A would maintain the same level of redundancy but change the RAID type, which does not reduce capacity. Options B and C do not directly address the FTT setting, which is the key factor in reducing capacity.
