Use case
An illustrative scenario, not a real incident.

Key point: BMC sensors show hardware state.
Why the other options are wrong
- A. The Slurm user list
- That holds no sensor data.
- C. The NGC catalog entry for the server model
- A catalog holds no sensor data.
- D. The Docker image layers
- Those hold no sensor data.
