Designing Cisco Data Center Infrastructure (DCID) — Question 77
An engineer is operating data center environment that hosts data-intensive financial applications. The applications are mostly processing HTTP/HTTPS data with large data segments, which results in a CPU contention due to the significant network processing.
Which set of Ethernet adapter policies must be selected to resolve the issue?
Answer options
- A. Receive Checksum Offload field set to Disabled TCP Segmentation Offload field set to Disabled Transmit Queues field: 32 - Ring Size field: 256
- B. Receive Checksum Offload field set to Enabled TCP Segmentation Offload field set to Disabled Transmit Queues field: 64 - Ring Size field: 128
- C. Receive Checksum Offload field set to Enabled TCP Segmentation Offload field set to Enabled Transmit Queues field: 128 - Ring Size field: 64
- D. Receive Checksum Offload field set to Disabled TCP Segmentation Offload field set to Enabled Transmit Queues field: 256 - Ring Size field: 128
Correct answer: C
Explanation
The correct answer is C because enabling both Receive Checksum Offload and TCP Segmentation Offload helps reduce CPU load by offloading these tasks to the network adapter. Options A and B disable necessary offloading features, which can lead to higher CPU utilization, while option D disables Receive Checksum Offload, hindering performance.
