Dell EMC Specialist – Systems Administrator, PowerEdge Server — Question 21

When using TimeFinder SnapVX, why would a redirect-on-write be changed to a copy-on-write?

Answer options

• A. Snapshot delta has used 80% of the SRP
• B. Prevent a new write from being demoted to a lower tier
• C. Back-end utilization exceeds 80%
• D. Improve wear rates on flash disks

Correct answer: D

Explanation

The correct answer is D because switching to copy-on-write can help improve the wear rates on flash disks by reducing the number of write cycles. Options A, B, and C are incorrect as they do not directly address the goal of enhancing wear rates, but rather focus on storage resource utilization and write demotion.
