Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe a CLI command you would use to inspect the status of an Infiniband network interface.
Keep your answer focused on the exact command, what status fields you would check, and how you would tell whether the link is healthy, degraded, or down. If useful, mention one follow-up command for deeper troubleshooting.
