How would you answer an interview scenario involving Azure availability and disaster recovery in Microsoft Azure?

For an interview scenario involving Azure availability and disaster recovery, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Azure resilience design uses availability zones, regional redundancy, backups, replication, and recovery planning to meet business continuity targets. In this scenario, given an RTO of 30 minutes and RPO of 5 minutes, explain how you would design and test recovery for an Azure web application, database, storage, and messaging dependencies. For production, define workload RTO/RPO first, map dependencies, use zone redundancy where appropriate, automate backups, test failover, document runbooks, and validate DNS and data recovery procedures. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
