Amazon Web Services SAA-C03 Question Answer

A company hosts an ecommerce application on AWS by using Amazon EC2 instances. The EC2 instances are spread across three Availability Zones behind an Application Load Balancer ALB. The EC2 instances are in an Auto Scaling group.

Some application users report that the application occasionally directs users who have already authenticated to the login page. The users must log in again.

The company needs a solution that will prevent the application from redirecting authenticated users to the login page.

Which solution will meet this requirement?

Manually terminate the EC2 instances. Wait for the Auto Scaling group to launch new EC2 instances automatically.

Configure the ALB to direct user activities to the appropriate EC2 instance through the IPv4 IP address of the instance that is registered as a target in the target group.

Apply session affinity with application-based stickiness at the target group level.

Configure the ALB to direct user activities to just one EC2 instance that is registered as a target in the target group.
