Question 180
An enterprise needs a business-continuity option for a regional natural disaster. Which high-level AWS choice is MOST suitable for the business need?
Explanation
Correct Answer
Consider an appropriate multi-Region disaster-recovery approach for the business RTO and RPO. This choice addresses the specific business requirement: Separate Regions offer distinct geographic failure domains beyond one Region's AZs. A clear way to confirm success is: A documented regional failover exercise meets recovery time and recovery point objectives. To sustain the result: Rehearse recovery and verify data replication rather than equating backups with instant failover.
