How would you determine whether the issue is with the application, database, infrastructure, network, or downstream services?
Tests whether you'd triage top-down using distributed traces to localize which hop in the call chain is slow or erroring, then correlate with each layer's own metrics (DB query time, infra CPU/network, downstream SLA) instead of guessing based on symptoms alone.
