NetApp Certified Implementation Engineer – ONTAP v3 — Question 7

An administrator is configuring their existing Ethernet network switches to provide iSCSI LUNs to several servers. The network switches are also used for other traffic from various hosts.
In this scenario, which statement is true?

Answer options

• A. Use multiple VLANs to isolate iSCSI traffic from other network traffic.
• B. Configure the MTU size to be larger on the switch and storage than on the host.
• C. Increase the ratio of access ports to trunk ports to 2:1.
• D. NetApp recommends using the same LIFs for NFS and iSCSI traffic.

Correct answer: A

Explanation

The correct answer is A because using multiple VLANs effectively isolates iSCSI traffic from other types of network traffic, enhancing performance and security. Option B is incorrect as the MTU should be consistent across the network to avoid fragmentation issues. Option C does not address the isolation need and is not a standard recommendation. Option D is misleading as it suggests a combined approach that may not be optimal for traffic management.
