Question 930
An enterprise needs a business-continuity option for a regional natural disaster. Which ongoing practice BEST sustains the intended result?
Explanation
Correct Answer
Rehearse recovery and verify data replication rather than equating backups with instant failover. This continuing control fits because Separate Regions offer distinct geographic failure domains beyond one Region's AZs. The associated appropriate response is: Consider an appropriate multi-Region disaster-recovery approach for the business RTO and RPO. An observable check is: A documented regional failover exercise meets recovery time and recovery point objectives.
