Amazon DVA-C02 Exam - Topic 5 Question 24 Discussion

Actual exam question for Amazon's DVA-C02 exam

Question #: 24
Topic #: 5

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, can you really store passwords in DynamoDB? That seems risky.

C sounds like overkill for just user management.

I think B is a bit too complex for this scenario.

A is definitely the way to go with Cognito!

I feel like option C is overkill for just user registration and login, but I can't quite recall why we wouldn't use a database for this purpose.

I practiced a similar question where using DynamoDB for user storage seemed like a good idea, but I wonder if it really minimizes management as required here.

I think option B sounds familiar, but I recall that managing IAM groups manually can lead to more overhead, which we want to avoid.

I remember studying about Amazon Cognito and how it simplifies user management, but I'm not entirely sure if it's the best fit for this scenario.

I'm not sure about the DynamoDB option. Storing user passwords directly in a database doesn't seem very secure. I think I'll need to rule that one out and focus on the Cognito and IAM role options.

Hmm, I'm a bit confused by the options here. I'm not sure if creating IAM roles for identity pools or managing permissions through an RDS database is the best approach for a serverless application. I'll need to think this through carefully.

This looks like a pretty straightforward question about implementing a user authentication solution for a serverless application. I think the key is to find the solution that minimizes operational overhead and ongoing management of user identities.

Ah, I see! Using Amazon Cognito user pools with social identity providers seems like the way to go. That would handle the user management for us and integrate nicely with the serverless architecture. I'm confident that's the right solution for this scenario.

I think the subcommand to start a new container is 'run'. That's the one I usually use for that.

I'm not entirely sure about this one. The wording is a bit convoluted, and I'm not confident I fully understand the relationship between the old and new equipment depreciation. I'll give it my best shot, but I may need to come back to this question.

I remember discussing practical kaizen training, but isn't that more about processes than specifically eliminating errors?

Okay, let me think this through step-by-step. The NTFS format program needs to reserve some space for the boot sectors and bootstrap code, so it's likely one of the answer choices. I'll eliminate the ones that seem too small or too large, and then decide between the remaining options.

From our practice questions, executing unit tests was often highlighted as crucial, but does the tester really fit into that role?

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.
