A company has a three-tier web application. An Application Load Balancer (ALB) is in front of Amazon EC2 instances that are in the ALB target group. An Amazon S3 bucket stores documents.

The company requires the application to meet a recovery time objective (RTO) of 60 seconds.

Which solution will meet this requirement?

A.

Replicate S3 objects to a second AWS Region. Create a second ALB and a minimum set of EC2 instances in the second Region. Ensure that the EC2 instances are shut down until they are needed. Configure Amazon Route 53 to fail over to the second Region by using an IP-based routing policy.

B.

Use AWS Backup to take hourly backups of the EC2 instances. Back up the S3 data to a second AWS Region. Use AWS CloudFormation to deploy the entire infrastructure in the second Region when needed.

C.

Create daily snapshots of the EC2 instances in a second AWS Region. Use the snapshots to recreate the instances in the second Region. Back up the S3 data to the second Region. Perform a failover by modifying the application DNS record when needed.

D.

Replicate S3 objects to a second AWS Region. Create a second ALB and a minimum set of EC2 instances in the second Region. Ensure that the EC2 instances in the second Region are running. Configure Amazon Route 53 to fail over to the secondary Region based on health checks.
