B and D are the answers

A. Turn on the sticky sessions feature (session affinity) on the ALB: Enabling sticky sessions on the Application Load Balancer (ALB) ensures that subsequent requests from a client are routed to the same backend EC2 instance. This helps maintain session continuity as all requests from the same client are directed to the same instance, allowing the session data to be stored and accessed consistently. D. Deploy an Amazon ElastiCache for Redis cluster to store customer session information: Amazon ElastiCache for Redis is an in-memory data store that can be used to store session information. By deploying an ElastiCache for Redis cluster, the company can store and manage customer session data in a fast and scalable manner. Redis provides durability by periodically persisting data to disk, ensuring session data is not lost even in the event of instance failures.

https://docs.aws.amazon.com/elasticloadbalancing/latest/application/sticky-sessions.html If your application has its own session cookie, then you can use application-based stickiness and the load balancer session cookie follows the duration specified by the application's session cookie. My choice is : A & B

Agree with B & D Sticky sessions mean that it send the traffic to the correct EC2 instance. It doesn't actually manage sessions, in my openion

A and D...
