Amazon Exam DVA-C02 Topic 6 Question 33 Discussion

Actual exam question for Amazon's DVA-C02 exam

Question #: 33
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.

Wait, you guys are actually considering anything other than Cognito? What is this, 2010? Cognito is the only sensible choice for a modern serverless app.

Ha! Imagine trying to manage an RDS database for user auth in a serverless app. Talk about overkill. Cognito is the clear winner here, folks.

Hmm, I'm not sure about Option D. Storing passwords in DynamoDB? That seems like a security nightmare waiting to happen. Cognito is definitely the way to go.

That's a valid point, but I still think using Amazon Cognito for user management is more secure and easier to manage in the long run.

I disagree, I believe option D is better as storing user information in DynamoDB with IAM policies provides a scalable and low operational overhead solution.

I think option A is the best choice because Amazon Cognito user pools can handle user registration and authentication efficiently.

I'm with Talia on this one. Cognito is the easiest and most secure way to handle authentication. Plus, you get all those social identity provider integrations out of the box!

Option A is the way to go! Cognito user pools are the perfect solution for managing user identities in a serverless app. Minimizes overhead and no need to manage users ourselves.
