Your question is Design for Traffic Spikes. 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 would you design a highly available service to handle a massive spike in traffic at X Development?
Explain how you would clarify the workload, protect dependencies, scale stateless and ML-serving components, and preserve availability when capacity or downstream systems are constrained. Cover traffic admission, graceful degradation, observability, and recovery. State assumptions explicitly rather than relying on unstated product or traffic details.
