An Ecommerce Company Is Running an Application on AWS

An ecommerce company is running an application on AWS. The company wants to create a standby disaster recovery solution in an additional Region that keeps the current application code. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB) . The instances run in an EC2 Auto Scaling group across multiple Availability Zones. The database layer is hosted on an Amazon RDS MySQL Multi-AZ DB instance. Amazon Route 53 DNS records point to the ALB. Which combination of actions will meet these requirements with the LOWEST cost? (Choose three.)

A) Configure a failover routing policy for the application DNS entry.
B) Configure a geolocation routing policy for the application DNS entry.
C) Create a cross-Region RDS read replica in the new standby Region.
D) Migrate the database layer to Amazon DynamoDB and enable global replication to the new standby Region.
E) Provision the ALB and Auto Scaling group in the new standby Region and set the desired capacity to match the active Region.
F) Provision the ALB and Auto Scaling group in the new standby Region and set the desired capacity to 1.
