Discuss Amazon DVA-C02 Exam Topic 2 Question 66

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.

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.

I would pick A because the tricky part is using a managed user directory with social providers to handle sign in, reducing auth overhead.

That wording clearly points to A as the choice.

Exactly! Security and ease of use are key.

Jolanda 26 days ago

A just feels like the most secure option.

D is risky, storing passwords in DynamoDB? No thanks.

Alisha 1 month ago

C is overkill, RDS adds unnecessary management.

Jolanda 1 month ago

B seems too complex, managing IAM groups is a hassle.

Alyssa 2 months ago

Right! No need to manage passwords directly.

Alisha 2 months ago

Plus, social logins make it easier for users.

Jolanda 2 months ago

A sounds good, less overhead for sure.

Alyssa 2 months ago

Agreed! Cognito simplifies user management.

Alisha 2 months ago

I think option A is the best choice.

D) sounds risky, storing passwords in DynamoDB? Really?

Willodean 3 months ago

Wait, why would you use RDS? Seems overkill.

Heike 3 months ago

B) sounds too complicated for this use case.

Ora 3 months ago

Totally agree, Cognito simplifies things!

A) is the best choice for user management.

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

Earlean 3 months ago

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

Micah 4 months ago

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?

Bonita 4 months ago

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.
