QuestionQ56

Networking and Content Delivery

A company operates a microservice on a group of Amazon EC2 instances. The EC2 instances are positioned behind an Application Load Balancer (ALB).

A CloudOps engineer must use Amazon Route 53 to create a record that maps the ALB URL to example.com.

Which record type meets this requirement?

Explanation

An Amazon Route 53 alias record can point to an Elastic Load Balancing Application Load Balancer and lets the zone-apex domain example.com resolve to the load balancer. Route 53 automatically follows changes to the load balancer’s underlying IP addresses; a CNAME record cannot be created at the zone apex.
