Question #: 24
Topic #: 5

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

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.

I see where both of you are coming from. But I think option B is a good compromise. Creating users in IAM groups could provide a good balance of simplicity and security.

I disagree, I believe option D is the way to go. Storing users and passwords in DynamoDB with an attached IAM policy seems simpler and easier to manage.
