Dell Technologies Proven Professional – Midrange Storage Solutions — Question 40

Which network option should be configured to provide the best iSCSI performance on a Dell Unity XT array?

Answer options

• A. Jumbo frames
• B. Disable flow control
• C. iSCSI offload
• D. Single VLAN for all traffic

Correct answer: C

Explanation

The correct choice, iSCSI offload, enhances performance by offloading iSCSI processing from the CPU to the network interface card, reducing latency. While Jumbo frames can improve throughput and disabling flow control can reduce delays, these options do not provide the same level of performance enhancement specific to iSCSI as offloading does. A single VLAN for all traffic may simplify management but does not inherently improve iSCSI performance.
