Use an RDS Cross-Region Read Replica.
C.
Configure AWS Backup to take continuous backups (Point-in-Time Recovery) and copy them to the DR region.
D.
Use AWS Database Migration Service (DMS) to replicate data to an S3 bucket in the DR region.
How to approach this question
Look for the native RDS feature that provides 5-minute RPO without running a replica.
Full Answer
C.Configure AWS Backup to take continuous backups (Point-in-Time Recovery) and copy them to the DR region.✓ Correct
Configure AWS Backup to take continuous backups (Point-in-Time Recovery) and copy them to the DR region.
RDS Point-in-Time Recovery (PITR) provides continuous backups, allowing restoration to any point within the last 35 days (typically meeting a 5-minute RPO). AWS Backup can manage this and copy the backups cross-region, satisfying the RPO/RTO without the cost of a running replica.
Common mistakes
Choosing Read Replica despite the explicit constraint against it.
