How to approach this question

Match the aggressive RTO/RPO metrics to the appropriate DR pattern (Hot, Warm, Cold).

Full Answer

C.A hot standby architecture in a secondary region with continuous asynchronous database replication.✓ Correct

A hot standby architecture in a secondary region with continuous asynchronous database replication.

RTO (Recovery Time Objective) is how fast you must recover. 15 minutes requires a 'Hot' standby where resources are already running. RPO (Recovery Point Objective) is how much data you can afford to lose. 5 minutes requires continuous replication, as daily or hourly backups would lose too much data.

Common mistakes

Confusing RTO and RPO, or selecting a cheaper option (Warm/Cold) that fails to meet the strict business metrics.

Your company is designing a disaster recovery (DR) plan for a critical application. The business requirements state a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 5 minutes. Which DR architecture should you implement?
