Your question is HA Database Architectures. 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).
Describe your experience evaluating trade-offs between different database architectures in high-availability environments at scale.
Discuss how you compare relational databases, distributed SQL systems, NoSQL databases, replication strategies, consistency models, partitioning, failover behavior, and operational complexity. Explain how workload characteristics and availability, latency, durability, consistency, and recovery requirements influence the design.
