Your question is Debugging Software vs Hardware. Take a moment with it on the right.
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).
How do you approach debugging a system where the issue might be in software or hardware?
Describe a practical, evidence-driven process for isolating the fault domain, coordinating with software and hardware owners, and minimizing disruption while testing hypotheses. Explain how you would document findings, decide when to escalate, and verify the fix.
