Answer: The Load Balancer does not have stickiness enabled
The Load Balancer does not have stickiness enabled - Sticky sessions are a mechanism to route requests to the same target in a target group. This is useful for servers that maintain state information to provide a continuous experience to clients. To use sticky sessions, the clients must support cookies. When a load balancer first receives a request from a client, it routes the request to a target, generates a cookie named AWSALB that encodes information about the selected target, encrypts the cookie, and includes the cookie in the response to the client. The client should include the cookie that it receives in subsequent requests to the load balancer. When the load balancer receives a request from a client that contains the cookie, if sticky sessions are enabled for the target group and the request goes to the same target group, the load balancer detects the cookie and routes the request to the same target.

You are managing a cloud-based file storage platform that utilizes an Internet-facing Application Load Balancer (ALB) to distribute incoming user requests across 10 registered Amazon EC2 instances. However, users are reporting an issue where they are required to re-authenticate every time they navigate to a different page on your website. This issue is not observed in your local machine or development environment.
What could be the cause of this problem?
A
Application Load Balancer is in slow-start mode, which gives ALB a little more time to read and write session data
B
The Load Balancer does not have TLS enabled
C
The Load Balancer does not have stickiness enabled
D
The EC2 instances are logging out the users because the instances never have access to the client IPs because of the Load Balancer
