Exam NCA-AIIO Topic 2 Question 2 Discussion

Actual exam question for NVIDIA's NCA-AIIO exam
Question #: 2
Topic #: 2
When using an InfiniBand network for an AI infrastructure, which software component is necessary for the fabric to function?

Suggested Answer: C Vote an answer

OpenSM (Open Subnet Manager) is essential for InfiniBand networks, managing the fabric by discovering topology, configuring switches and host channel adapters (HCAs), and handling routing. Without it, the fabric cannot operate. Verbs is an API for RDMA, and MPI is a communication protocol, but OpenSM is the critical software component for functionality.
