Show Suggested Answer Hide 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.

Wait, why would you use RDS? Seems overkill.

I recall discussing DynamoDB in relation to user data storage, but I'm not convinced that option D is secure enough for handling passwords.

I feel like option C is overkill for this scenario. Using RDS just to manage user identities seems unnecessary when there are simpler solutions.

I'm not entirely sure, but I remember something about IAM roles and groups. Option B might be too complex for just user registration, right?

I think option A sounds familiar because we talked about using Amazon Cognito for user management in our last study group. It seems like a good fit for minimizing overhead.
