Question #: 29
Topic #: 6

A developer is designing a serverless application for a game in which users register and log in through a web browser The application makes requests on behalf of users to a set of AWS Lambda functions that run behind an Amazon API Gateway HTTP API

The developer needs to implement a solution to register and log in users on the application's sign-in page. The solution must minimize operational overhead and must minimize ongoing management of user identities.

Which solution will meet these requirements'?

ACreate Amazon Cognito user pools for external social identity providers Configure 1AM roles for the identity pools.

BProgram the sign-in page to create users' 1AM groups with the 1AM roles attached to the groups

CCreate an Amazon RDS for SQL Server DB instance to store the users and manage the permissions to the backend resources in AWS

DConfigure the sign-in page to register and store the users and their passwords in an Amazon DynamoDB table with an attached IAM policy.

Show Suggested Answer

Suggested Answer: A

Amazon Cognito User Pools:A managed user directory service, simplifying user registration and login.

Social Identity Providers:Cognito supports integration with external providers (e.g., Google, Facebook), reducing development effort.

IAM Roles for Authorization:Cognito-managed IAM roles grant fine-grained access to AWS resources (like Lambda functions).

Operational Overhead:Cognito minimizes the need to manage user identities and credentials independently.

Option D might work, but storing passwords in DynamoDB? That's a recipe for disaster. Better stick with the industry-standard solution in Option A.

Option A seems like the best choice here. Cognito user pools can handle user registration and authentication with minimal overhead, and the IAM roles provide the necessary access control.

I disagree, I believe option D is better as it involves storing user information in an Amazon DynamoDB table with an attached IAM policy for security.
