Q29Network Design
A company runs a web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The ALB serves as the origin for an Amazon CloudFront distribution. The company wants to implement a custom authentication system that provides a token to authenticated customers. Before delivering content, the web application must ensure that GET/POST requests originate from authenticated customers. A network engineer must design a solution that enables the web application to identify authorized customers. What is the **MOST operationally efficient** solution that satisfies these requirements?
