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).
We notice a sudden metric drop in our real-time grid monitoring dashboard; what is your step-by-step process for identifying the root cause?
Explain how you would validate the metric definition, confirm the drop is real, localize the change across grid assets and time, and distinguish an operational event from a data pipeline or dashboard issue. Describe the checks, data sources, analyses, and communication steps you would use before recommending action.
