   A healthcare company has a documented disaster recovery plan for its application that runs on EC2 instances in us-east-1. The plan uses AWS Backup to copy EBS snapshots and RDS snapshots to us-west-2. During a recent regional outage simulation, the recovery team discovered that the RTO was exceeded because the EC2 instances took too long to launch and configure. Which improvement would MOST effectively reduce the recovery time?

   • APre-create an Amazon Machine Image (AMI) in the secondary Region and use an EC2 Auto Scaling group with a launch template to deploy instances on demand.
   • BUse AWS CloudFormation to redeploy the entire stack in the secondary Region, including the EC2 instances and RDS database.
   • CIncrease the frequency of AWS Backup jobs from daily to hourly.
   • DEnable detailed CloudWatch monitoring on the EC2 instances to detect failures faster.
