Topic 1 Question 210
A company has an application that is deployed to two AWS Regions in an active-passive configuration. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB) in each Region. The instances are in an Amazon EC2 Auto Scaling group in each Region. The application uses an Amazon Route 53 hosted zone for DNS. A SysOps administrator needs to configure automatic failover to the secondary Region.
What should the SysOps administrator do to meet these requirements?
Configure Route 53 alias records that point to each ALB. Choose a failover routing policy. Set Evaluate Target Health to Yes.
Configure CNAME records that point to each ALChoose a failover routing policy. Set Evaluate Target Health to Yes.
Configure Elastic Load Balancing (ELB) health checks for the Auto Scaling group. Add a target group to the ALB in the primary Region. Include the EC2 instances in the secondary Region as targets.
Configure EC2 health checks for the Auto Scaling group. Add a target group to the ALB in the primary Region. Include the EC2 instances in the secondary Region as targets.

Active / Standby = one region active at a time. Health checks and Route53.

To configure automatic failover to the secondary Region for an application that is deployed to two AWS Regions in an active-passive configuration, the following steps should be taken:
Configure Route 53 alias records that point to each ALB in the two Regions. Choose a failover routing policy, such as Failover or Geolocation. Set Evaluate Target Health to Yes to ensure that Route 53 only responds to DNS queries with healthy ALB endpoints.
