Your question is AuthN and AuthZ in Distributed Systems. 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 do you handle authentication and authorization in a distributed system? Explain how you would define service boundaries, select an identity model, manage credentials and tokens, and coordinate implementation across teams. Discuss rollout sequencing, failure handling, observability, and security trade-offs.
