- It works independently of the OS.
Use case
An illustrative scenario, not a real incident.
A technician sets up each BMC first, so that later work can be remote.

Key point: The BMC comes first.
Why the other options are wrong
- B. GPU-to-GPU links for training
- That is NVLink.
- C. A file share for model data
- That is storage.
- D. Scheduling of cluster jobs
- That is a scheduler.
