NetApp Certified Design Engineer – SAN — Question 13

You want to ensure maximum performance of iSCSI LUNs on an AFF A220.
In this scenario, which two actions will accomplish this task? (Choose two.)

Answer options

• A. Disable flow control.
• B. Configure virtual LAN (VLAN).
• C. Enable flow control.
• D. Enable jumbo frames.

Correct answer: C, D

Explanation

Enabling flow control helps prevent packet loss during high traffic, while enabling jumbo frames allows larger packets to be transmitted, reducing overhead and improving throughput. Disabling flow control can lead to congestion and packet drops, and configuring VLANs, while beneficial for network segmentation, does not directly enhance iSCSI performance.
