A company has migrated its legacy on-premises web application to an Amazon EC2 instance. The web application requires a single static public IP address to accept traffic and process requests. End users must be able to reach the web application through the example.com domain. A SysOps administrator must implement a solution that maintains the web application with the least amount of effort.

Which combination of actions will meet these requirements? (Choose two.)

A. Configure an Application Load Balancer (ALB). Add the EC2 instance to a target group that is associated with the ALB.
B. Create an Amazon Route 53 A record for the associated EC2 IP address.
C. Create an Amazon Route 53 CNAME record for the associated EC2 IP address.
D. Create an Elastic IP address, and associate it with the EC2 instance.
E. Create an Auto Scaling group with a minimum capacity of 1 and a maximum capacity of 2.

an EC2 instance -- remove what has 'group', remove A (target group), remove E (Auto Scaling group). --> B, C, or D? CNAME is not related to IP address. --> remove C. --> Choose B, D.

D. Create an Elastic IP address, and associate it with the EC2 instance. This will give your EC2 instance a static public IP address that does not change, even if you stop and start the instance or if there are underlying infrastructure changes. This is important to maintain the single static public IP address required by the web application. B. Create an Amazon Route 53 A record for the associated EC2 IP address. After obtaining the Elastic IP address from step 1, you can create a simple A record in Amazon Route 53 that points the example.com domain to the Elastic IP address. This will allow end users to reach the web application through the example.com domain.
