A link is up, but its error counters climb. What is the concern?
Why C is the answer
Signal quality
A link can be up and still marginal.
In detail
- A link can be up and still have poor signal quality.
- Up does not mean healthy.
Use case
An illustrative scenario, not a real incident.
A link shows up, but its errors climb, so its signal quality is marginal.

Key point: Rising errors mean weak signal quality.
Why the other options are wrong
- A. Container image size
- That is about images.
- B. Prompt length
- That is about LLMs.
- D. Slurm fairshare
- That is about job priority.
