A retail company runs a customer-facing web application on EC2 instances in an Auto Scaling group across two Availability Zones in the us-east-1 Region. The application is behind an Application Load Balancer (ALB). The company wants to increase availability so that the application remains available even if an entire Availability Zone fails. Which change best meets this requirement?

Use an Amazon Route 53 failover routing policy to redirect traffic to a static website hosted in Amazon S3 during a failure.

Add a third Availability Zone to the Auto Scaling group and configure the ALB to route traffic to all three Availability Zones.

Increase the minimum and maximum size of the Auto Scaling group to ensure more instances are running.

Place the Auto Scaling group in a single Availability Zone and use a larger instance type to handle more traffic.
