Additional explanation for question

[CarlosQ]

In the question with this scenario:

“A food delivery company plans to host a stateful web application that
runs on Amazon EC2 instances in an Auto Scaling Group (ASG). An
Application Load Balancer (ALB) is configured to distribute traffic with
a single target group. For faster content delivery, the ALB is set as
the origin for an Amazon CloudFront distribution. Few hours after
deployment, users started reporting erratic behavior on the web
application where they are logged out randomly.”

The incorrect answer “Activate group-level stickiness on the ALB listener rule.” should have a link to this AWS page: “Choosing a stickiness strategy for your load balancer” (https://docs.aws.amazon.com/prescriptive-guidance/latest/load-balancer-stickiness/welcome.html) that explains “Sticky sessions” vs “Target group stickiness“

Hi CarlosQ,

Thanks for posting here. We have overhauled the explanation, and the change will be reflected in our practice exams soon. Thanks again, and we wish you all the best in your upcoming AWS exam!
