Amazon Web Services Amazon AWS Certified Advanced Networking - Specialty ANS-C01 Question # 78 Topic 8 Discussion

ANS-C01 Exam Topic 8 Question 78 Discussion:
Question #: 78
Topic #: 8

A company hosts a web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The ALB is the origin in an Amazon CloudFront distribution. The company wants to implement a custom authentication system that will provide a token for its authenticated customers.

The web application must ensure that the GET/POST requests come from authenticated customers before it delivers the content. A network engineer must design a solution that gives the web application the ability to identify authorized customers.

What is the MOST operationally efficient solution that meets these requirements?
A.

Use the ALB to inspect the authorized token inside the GET/POST request payload. Use an AWS Lambda function to insert a customized header to inform the web application of an authenticated customer request.

B.

Integrate AWS WAF with the ALB to inspect the authorized token inside the GET/POST request payload. Configure the ALB listener to insert a customized header to inform the web application of an authenticated customer request.

C.

Use an AWS Lambda@Edge function to inspect the authorized token inside the GET/POST request payload. Use the Lambda@Edge function also to insert a customized header to inform the web application of an authenticated customer request.

D.

Set up an EC2 instance that has a third-party packet inspection tool to inspect the authorized token inside the GET/POST request payload. Configure the tool to insert a customized header to inform the web application of an authenticated customer request.
