Q85 Single choice

A company is building a new application that will run on Amazon EC2 instances in one AWS Region. The EC2 instances will use Amazon EBS volumes. The business continuity plan requires the ability to fail over to a secondary Region. The failover must have a recovery time objective (RTO) of 4 hours and a recovery point objective (RPO) of 1 hour.

Which solution will meet these requirements MOST cost-effectively?

A
Deploy the application on a smaller number of EC2 instances in the secondary Region. Configure the secondary Region to synchronize with the primary Region.
B
Refactor the application to use an active-active strategy across both Regions. Use Amazon Route 53 and health checks to route requests to the lowest-latency Region.
C
Use AWS Backup to create a backup plan for the EC2 instances that includes cross-Region backups to the secondary Region. Restore the EC2 instances in the secondary Region in case of failover.
D
Deploy a similar number of EC2 instances in the secondary Region. Use AWS DataSync to transfer the data on the EBS volumes from the primary Region to the secondary Region.
