Click the Exhibit button. A customer is testing a newly installed NetApp AFF A400 all-flash HA storage system. An SVM for FCP with a LUN on Node 1 has been configured, and a server has been connected as shown in the exhibit. For testing, the engineer plans to do a storage failover of Node 1. After the failover, what is the expected status of the marked path?

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

A.
Connect host and storage ports to the same switches.
Answers
A.
Connect host and storage ports to the same switches.
B.
Decrease the default queue depth on the host to eight.
Answers
B.
Decrease the default queue depth on the host to eight.
C.
Zone the host by using the host WWPNs.
Answers
C.
Zone the host by using the host WWPNs.
D.
Configure Jumbo frames In the entire data path.
Answers
D.
Configure Jumbo frames In the entire data path.
Suggested answer: A, D

Explanation:

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.
