NetApp Certified Data Administrator (NCDA) – ONTAP v3 — Question 29

Several clients are accessing an ONTAP SnapMirror DP destination volume. Some clients frequently access the newest SnapMirror volume data. Accessing this data is much slower when compared to clients that directly access data on the source. You use the wafl scan status command against the destination.
What is a symptom of the problem in this scenario?

Answer options

• A. blocks used summary update
• B. active bitmap rearrangement
• C. container block reclamation
• D. volume deswizzling

Correct answer: D

Explanation

The correct answer, D (volume deswizzling), indicates that the data layout on the destination volume is not optimal for performance, leading to slower access times. Options A, B, and C refer to other processes or issues that do not directly relate to the performance problem observed in this scenario.
