Question

A financial services company runs its primary application in a single cloud region. Regulatory requirements mandate a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 1 hour in the event of a full regional outage. The business wants to minimize ongoing cost while still meeting these targets. Which disaster recovery design best satisfies these requirements?

Accepted Answer

Deploy a warm standby in a second region with a scaled-down replica of the application tier and continuous asynchronous database replication, scaling up compute during failover

Answer

Use a backup-and-restore strategy that stores nightly snapshots in a second region and rebuilds the environment on demand after an outage

Answer

Deploy a fully active-active multi-region architecture with synchronous database replication and equal capacity in both regions

Answer

Rely on multi-AZ deployment within the primary region with synchronous replication across availability zones
