Question

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.

Answer

A. Configure an Application Load Balancer (ALB). Add the EC2 instance to a target group that is associated with the ALB.
D. Create an Elastic IP address, and associate it with the EC2 instance.

Explanation

Option A allows the web application to be served through the ALB, which can distribute incoming traffic across multiple instances. The target group associates the EC2 instance with the ALB, ensuring that incoming requests are routed to the appropriate instance.

Option D creates a static public IP address (Elastic IP address) that can be associated with the EC2 instance. This ensures that the web application can be accessed through the example.com domain and has a static IP address for inbound traffic.

Option B (creating an Amazon Route 53 A record) and Option C (creating an Amazon Route 53 CNAME record) are not necessary for this scenario, as the web application already has a static public IP address that can be used to route traffic.

Option E (creating an Auto Scaling group) is not relevant to this scenario, as it does not address the requirements of the web application.
