NetApp Certified Implementation Engineer – ONTAP v3 — Question 50

You have a two-node NetApp ONTAP cluster that is hosting FC LUNs for 90 SAN hosts. The hosts are experiencing occasional performance problems and receiving QFULL responses from the cluster nodes.
Which action would solve this issue?

Answer options

• A. Increase the queue depth on the target ports.
• B. Increase the queue depth on the initiator ports.
• C. Configure additional FC target ports.
• D. Configure additional FC ports on the hosts.

Correct answer: A

Explanation

Increasing the queue depth on the target ports allows more outstanding I/O requests to be processed simultaneously, which can alleviate QFULL conditions. Options B, C, and D do not directly address the root cause of the queue depth limitation on the target ports, making them less effective solutions for this specific performance issue.
