Your question is Minimizing Latency Globally. 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).
What strategies do you employ to minimize latency in a globally distributed system?
Discuss the architectural, networking, data-serving, and ML inference techniques you would consider. Explain how you would measure latency, handle regional failures, and balance performance against consistency, cost, and model quality.
