A company runs a web application on Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). The application stores data in an Amazon Aurora MySQL DB cluster. The company needs a disaster recovery (DR) solution. The acceptable recovery time objective is up to 30 minutes. The DR solution does not need to serve customers while the primary infrastructure is healthy. Which solution meets these requirements?

The correct solution establishes a pilot light disaster recovery strategy, which aligns with the 30-minute RTO. Deploying a minimal Auto Scaling group and ALB in a second region means core infrastructure is ready to scale up quickly. An Aurora global database provides fast, asynchronous replication of the database across regions, enabling rapid failover with minimal data loss. Route 53 active-passive failover directs traffic to the DR region only when the primary fails, ensuring the DR site isn't active during normal operations. Incorrect options: Updating the Auto Scaling group to include EC2 instances from a second region is not how cross-region DR is typically implemented; separate Auto Scaling groups are used. Active-active failover is unnecessary given the requirement that the DR solution does not need to serve customers while the primary is healthy, and it's more complex. Relying on AWS Backup for Aurora data restore would likely exceed the 30-minute RTO due to the time required for restoration. Setting the Auto Scaling group desired capacity to zero means no instances are running, which would increase recovery time beyond 30 minutes to provision and launch new instances.
