Exam NCA-AIIO Topic 2 Question 11 Discussion

Actual exam question for NVIDIA's NCA-AIIO exam
Question #: 11
Topic #: 2
When should RoCE be considered to enhance network performance in a multi-node AI computing environment?

Suggested Answer: C Vote an answer

RoCE (RDMA over Converged Ethernet) enhances network performance by offloading data transport to the NIC via RDMA, bypassing CPU involvement. It's particularly valuable when high CPU utilization limits bandwidth usage, as it reduces overhead and unlocks full link capacity.
While RoCE can handle storage traffic, it's less effective with high packet loss (requiring reliable networks), making CPU- bound scenarios its prime use case.
