After installing GPUs, how do you confirm the hardware is sound?
Why A is the answer
Confirm the count, then run a diagnostic
Validate before handing the system to users.
In detail
- Confirm the count, then run a diagnostic.
- Validate before users arrive.
Use case
An illustrative scenario, not a real incident.
A technician confirms the GPU count, then runs a diagnostic before handover.

Key point: Count, then diagnose.
Why the other options are wrong
- B. Trust the packing list that came with the order
- A list is not a test.
- C. Start a production job and watch for failures
- Production is not a test.
- D. Check whether the server chassis is warm
- Heat proves nothing.
