Question

An alert fires for elevated errors, but every dashboard you open looks normal. How do you tell whether it's a real incident or a false alarm?

What a strong answer looks like

Stop the bleeding first (mitigate), then form hypotheses from real signals. Separate root cause from symptom, communicate status as you go, and close with what prevents a repeat.

Diagram & narrate the incident
