The correct answer is A. Deploy the EC2 instances in an Auto Scaling group across multiple Availability Zones. Configure E. Configure ALB health checks to monitor the target EC2 instances. Spreading your EC2 instances across multiple Availability Zones (AZs) in an Auto Scaling group and placing them behind the ALB ensures that if one AZ goes down, traffic is automatically routed to healthy instances in the other AZs.

Question
A company runs an application on Amazon EC2 instances that are behind an Application Load Balancer (ALB). The application supports customers in Europe and runs in a single Availability Zone in the eu-west-1 Region. The company hosts its DNS records in Amazon Route 53. A SysOps administrator needs to implement a solution to make the application highly available. The solution must minimize application downtime. Which combination of actions will meet these requirements? (Choose two.)
Options
- ADeploy the EC2 instances in an Auto Scaling group across multiple Availability Zones. Configure
- BDeploy the EC2 instances in multiple Availability Zones. Configure Route 53 latency-based routing.
- CConfigure Route 53 health checks to monitor the ALB.
- DConfigure Route 53 health checks to monitor the target EC2 instances.
- EConfigure ALB health checks to monitor the target EC2 instances.

Explanation
Spreading your EC2 instances across multiple Availability Zones (AZs) in an Auto Scaling group and placing them behind the ALB ensures that if one AZ goes down, traffic is automatically routed to healthy instances in the other AZs. ALB health checks on the target EC2 instances make sure the load balancer only sends traffic to healthy instances, minimizing downtime due to unhealthy or unreachable backends.
