Exam NCA-AIIO Topic 3 Question 30 Discussion

Actual exam question for NVIDIA's NCA-AIIO exam
Question #: 30
Topic #: 3
How many distinct network fabrics are in an AI cluster?

Suggested Answer: A Vote an answer

An AI cluster typically employs three distinct network fabrics: one for management and client traffic (e.g., Ethernet), one for storage I/O (e.g., accessing datasets), and one for low-latency RDMA interconnects (e.g., InfiniBand or RoCE) between compute nodes for tasks like gradient synchronization. This separation optimizes performance, scalability, and reliability, distinguishing AI clusters from simpler setups.
