A legacy web app was moved from on-premises to a single EC2 instance and must keep a fixed public IP for client traffic. Users access the app using example.com. You need a solution that requires minimal ongoing maintenance. Which two actions together satisfy these requirements? (Choose two.)

The correct options are to allocate an Elastic IP and associate it with the EC2 instance, and then create a Route 53 A record that points example.com to the instance’s public IP address. An Elastic IP provides a fixed public IP address that can be remapped to different instances, ensuring the web app always has the same external IP even if the underlying EC2 instance changes (e.g., due to stop/start cycles). A Route 53 A record maps a domain name directly to an IP address, fulfilling the requirement for users to access the app via example.com. Provisioning an Application Load Balancer is unnecessary for a single EC2 instance and adds complexity. A CNAME record cannot point directly to an IP address; it must point to another domain name. An Auto Scaling group is not required as the question specifies a single EC2 instance and doesn't mention scalability needs.
