NetApp Certified Implementation Engineer – ONTAP v4 — Question 13

A customer has demanding database servers, which require larger I/O queue counts and queue depths.
What should be done to increase these parameters for certain hosts?

Answer options

• A. Add the hosts to the subsystem with high priority.
• B. Decrease the QoS policy for the volumes that are in use by the namespaces.
• C. Increase the QoS policy for the given namespace.
• D. Increase the queue depth for the given namespace.

Correct answer: D

Explanation

Increasing the queue depth for the given namespace directly allows for a higher number of I/O operations to be processed simultaneously, which is essential for demanding database servers. The other options either do not directly impact the queue depth or may reduce performance by lowering QoS policies or prioritizing hosts incorrectly.
