NEW 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?

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

Answer: C

Explanation:
VLANs offer specific benefits, such as increased security and improved network reliability that you might want to leverage in iSCSI.
