How would you answer an interview scenario involving disaster recovery and business continuity in Cloud Architecture?

For an interview scenario involving disaster recovery and business continuity, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Disaster recovery restores service and data after major failure according to business-defined recovery time and recovery point objectives. In this scenario, a business requires a one-hour RTO and fifteen-minute RPO. Explain the architecture choices those objectives drive. For production, define RTO and RPO first, choose backup or warm/hot standby patterns accordingly, automate recovery, and run regular exercises. 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.
