NetApp Certified Storage Associate (NCSA) — Question 27

A customer observes write latencies above 40 ms on a clustered Data ONTAP system with two FAS3220s for a period of several minutes each night. During performance analysis, you discover that several back-to-back Cps occur.
In this scenario, which two configuration changes will reduce the write latencies? (Choose two.)

Answer options

• A. Move the volume with the highest write load to an aggregate with faster disks.
• B. Migrate the LIF with the highest network receive rate to a faster port.
• C. Add more disks to the aggregate.
• D. Add flash cache cards to the nodes.

Correct answer: A, D

Explanation

Moving the volume with the highest write load to an aggregate with faster disks (A) will improve performance by reducing latency related to disk I/O. Adding flash cache cards to the nodes (D) enhances read and write performance by providing faster access to frequently used data. The other options, while potentially helpful, do not directly address the write latencies in the same effective manner.
