A company has deployed a web service that runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The company has deployed the application in us-east-1. The web service uses Amazon Route 53 records for DNS requests for example.com. The records are configured with health checks that assess the availability of the web service. A second environment has been deployed into eu-west-1. The company requires traffic to be routed to the environment that provides the lowest latency for user requests. In the event of a regional outage, traffic should be directed to the alternate Region. Which configuration will achieve these requirements?
