NetApp Certified Storage Associate (NCSA) — Question 9

A Linux client is experiencing low throughput when reading a very large file using NFS. Network counters suggest there is packet drop in the network. To confirm whether dropped packets affect the Linux client, you are collecting network traces from the affected systems.
In this scenario, which two actions would be used? (Choose two.)

Answer options

• A. Use the tcpdump command on the Linux system.
• B. Use the pktt command on the NetApp controller.
• C. Use the traceroute command on the network switch.
• D. Use the tcptrace command on a Windows client in a separate subnet.

Correct answer: B, C

Explanation

The correct actions are B and C. Using the pktt command on the NetApp controller allows you to analyze packet traffic relevant to the NFS operations, while the traceroute command on the network switch can help identify routing issues or delays. Options A and D are not suitable because tcpdump is not as effective for this scenario, and tcptrace on a Windows client would not provide relevant information for the Linux client's NFS performance.
