AWS Certified Developer Associate Practice Test 5

Correct answer - "The Load Balancer does not have stickiness enabled" : By default, a Classic Load Balancer routes each request independently to the registered instance with the smallest load. However, you can use the sticky session feature (also known as session affinity), which enables the load balancer to bind a user's session to a specific instance. This ensures that all requests from the user during the session are sent to the same instance.

"The application must have a bug" - Not possible because we established that it works with at least 1 server

"The EC2 instances log out users because they don't see their true IP's" - Elastic Load Balancing stores the IP address of the client in the X-Forwarded-For request header and passes the header to your server so you can read it if needed in your application

"The Load Balancer does not have TLS enabled" - SSL / TLS does not impact stickiness.
