VMware App Volumes 4 Specialist — Question 20

Which two storage policy changes require a full rebuild of all components for an object? (Choose two.)

Answer options

• A. Increase the number of disk stripes for an object from 2 to 3.
• B. Increase the IOPS limit for an object.
• C. Reduce the Primary Failures to Tolerate from 2 to 1 for an object using a failure tolerance method of RAID-1 (Mirroring.)
• D. Disable object checksum on an object.
• E. Change the failure tolerance method of an object from RAID-1 (Mirroring) to RAID-5 (Erasure Coding).

Correct answer: C, E

Explanation

The correct answers, C and E, require a full rebuild because they fundamentally change the failure tolerance and redundancy aspects of the object. Reducing the Primary Failures to Tolerate alters how data is replicated, while changing the failure tolerance method affects the underlying storage architecture. Options A, B, and D do not necessitate a full rebuild as they do not impact the structural redundancy of the object.
