Actual exam question for NetApp's NS0-521 exam

Question #: 21
Topic #: 5

A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.)

AConnect host and storage ports to the same switches.

BDecrease the default queue depth on the host to eight.

CZone the host by using the host WWPNs.

DConfigure Jumbo frames In the entire data path.

Show Suggested Answer

Suggested Answer: A, D

To ensure the best performance in an iSCSI SAN implementation:

Connect host and storage ports to the same switches: This minimizes latency and maximizes the efficiency of data paths by ensuring direct connections within the same network segment.

Configure Jumbo frames in the entire data path: Setting a larger Maximum Transmission Unit (MTU) size reduces the overhead for processing each packet, thus improving overall network performance. Ensuring Jumbo frames are configured end-to-end in the data path is crucial for optimal performance.

I think zoning the host by using the host WWPNs is crucial to ensure security and prevent unauthorized access.

Wait, is this a trick question? I'm pretty sure the correct answer is to unplug everything and see if it works better.
