How many distinct network fabrics are in an AI cluster?

The correct answer is A. 3. 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…

Explanation

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.
