Answer is B and E. Refer url : https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Cookies.html You can configure each cache behavior to do one of the following: Forward all cookies to your origin – CloudFront includes all cookies sent by the viewer when it forwards requests to the origin. https://docs.aws.amazon.com/elasticloadbalancing/latest/application/sticky-sessions.html By default, an Application Load Balancer routes each request independently to a registered target based on the chosen load-balancing algorithm.

B & E is correct answer. Enable sticky session + forward Cookie because ALB sticky session works based on cookie.

D. Enabling group-level stickiness on the ALB listener rule does not exist as an option. While ALB supports sticky sessions through target group settings, there is no concept of group-level stickiness at the listener rule level.

Option C (header forwarding in the CloudFront distribution) could potentially help if the application uses headers to maintain session state. However, the question suggests that this is a cookie-based issue. Hence Options B & E are correct.

im sticking with CE with this one...again might be wrong, but logically, the questions says "Stateful" web application, meaning it comes from one host, header can be set from the one stateful web application to route to only one destination...configuring cookie based might overload the process, which explains the logout issue...but i maybe wrong, just a suggestion Header based caching: https://aws.amazon.com/premiumsupport/knowledge-center/configure-cloudfront-to-forward-headers/ cookie based caching: https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Cookies.html
