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).
Describe the trade-offs between different database architectures for a high-traffic application.
Clarify how traffic patterns, consistency requirements, data relationships, availability targets, and operational constraints influence the choice. Discuss how the design should evolve as traffic and data volume grow, including replication, partitioning, caching, failure recovery, and observability.
