What does BCM use to give compute nodes a consistent operating system?
Why C is the answer
Software images
Nodes are provisioned from images.
In detail
- Nodes are provisioned from software images.
- Change the image, not each node.
Use case
An illustrative scenario, not a real incident.
Each compute node boots from one software image, so all nodes match.

Why the other options are wrong
- A. Prompt templates
- That is an LLM term.
- B. Docker tags alone
- Those label containers.
- D. Partition keys
- That is an InfiniBand term.
