Question 680

Explanation
Correct Answer
Separate Regions offer distinct geographic failure domains beyond one Region's AZs. This principle explains why the suitable decision is: Consider an appropriate multi-Region disaster-recovery approach for the business RTO and RPO. The confirming observation would be: A documented regional failover exercise meets recovery time and recovery point objectives. A useful continuing practice is: Rehearse recovery and verify data replication rather than equating backups with instant failover.
