A company wants to restrict access to the content of its web application. The company needs to protect the content by using authorization techniques that are available on AWS. The company also wants to implement a serverless architecture for authorization and authentication that has low login latency.

The solution must integrate with the web application and serve web content globally. The application currently has a small user base, but the company expects the application's user base to increase

Which solution will meet these requirements?

A.

Configure Amazon Cognito for authentication. Implement Lambda@Edge for authorization. Configure Amazon CloudFront to serve the web application globally

Answers
A.

Configure Amazon Cognito for authentication. Implement Lambda@Edge for authorization. Configure Amazon CloudFront to serve the web application globally

B.

Configure AWS Directory Service for Microsoft Active Directory for authentication. Implement AWS Lambda for authorization. Use an Application Load Balancer to serve the web application globally.

Answers
B.

Configure AWS Directory Service for Microsoft Active Directory for authentication. Implement AWS Lambda for authorization. Use an Application Load Balancer to serve the web application globally.

C.

Configure Amazon Cognito for authentication. Implement AWS Lambda for authorization Use Amazon S3 Transfer Acceleration to serve the web application globally.

Answers
C.

Configure Amazon Cognito for authentication. Implement AWS Lambda for authorization Use Amazon S3 Transfer Acceleration to serve the web application globally.

D.

Configure AWS Directory Service for Microsoft Active Directory for authentication. Implement Lambda@Edge for authorization. Use AWS Elastic Beanstalk to serve the web application globally.

Answers
D.

Configure AWS Directory Service for Microsoft Active Directory for authentication. Implement Lambda@Edge for authorization. Use AWS Elastic Beanstalk to serve the web application globally.

Suggested answer: A

Explanation:

Amazon Cognito provides scalable, serverless authentication, and Lambda@Edge is used for authorization, providing low-latency access control at the edge. Amazon CloudFront serves the web application globally with reduced latency and ensures secure access for users around the world. This solution minimizes operational overhead while providing scalability and security.

Option B (Directory Service): Directory Service is more suitable for enterprise use cases involving Active Directory, not for web-based applications.

Option C (S3 Transfer Acceleration): S3 Transfer Acceleration helps with file transfers but does not provide authorization features.

Option D (Elastic Beanstalk): Elastic Beanstalk adds unnecessary overhead when CloudFront can handle global delivery efficiently.
