Designing Cisco Data Center Infrastructure (DCID) — Question 206

A network engineer is configuring an Ethernet Adaptor Policy for a server in Cisco UCS. The CPU must be able to process large TCP packets, and RSS network receive processing must be shared across processors whenever possible. How must the policy be configured?

Answer options

• A. Enable TCP Large Receive Offload and Receive Side Scaling.
• B. Disable TCP Large Receive Offload and enable Receive Side Scaling.
• C. Disable TCP Large Receive Offload and Receive Side Scaling.
• D. Enable TCP Large Receive Offload and disable Receive Side Scaling.

Correct answer: A

Explanation

The correct choice, A, is appropriate because enabling TCP Large Receive Offload allows the CPU to efficiently handle large packets, while Receive Side Scaling distributes the processing load across multiple processors. Options B and C do not leverage these features, which could hinder performance, and option D disables a crucial feature that aids in processing large TCP packets efficiently.
