A workload requires recovery from a complete AWS Region failure with an RPO measured in minutes. Which combination BEST meets that target?
AStoring logs in CloudWatch Logs with default retention
BA single EC2 instance with a Reserved Instance commitment
CMulti-region active-passive deployment with continuous cross-region data replication (e.g. Aurora Global Database, S3 Cross-Region Replication, DynamoDB Global Tables)
DMulti-AZ deployment in a single Region with EBS snapshots taken weekly
Answer & Solution
Correct answer: C. Multi-region active-passive deployment with continuous cross-region data replication (e.g. Aurora Global Database, S3 Cross-Region Replication, DynamoDB Global Tables)
Multi-Region with cross-Region replication is what survives a Region-wide outage with minute-scale RPO. Multi-AZ does not. Reserved Instances are a pricing model. CloudWatch log retention has nothing to do with cross-Region DR.
