AWS Certified Developer – Associate — Question 175

A developer is designing a web application in which new users will use their email addresses to create accounts. Millions of users are expected to sign up. The application will store attributes for each user.

Which AWS service or feature should the developer implement to meet these requirements?

Answer options

• A. Amazon Cognito user pools
• B. AWS Mobile Hub User File Storage
• C. AWS AppSync
• D. AWS Mobile Hub Cloud Logic

Correct answer: A

Explanation

Amazon Cognito user pools are specifically designed for handling user authentication and management, making them the ideal choice for the application's requirements. The other options, such as AWS Mobile Hub User File Storage and AWS Mobile Hub Cloud Logic, do not provide the necessary user management capabilities, while AWS AppSync is primarily focused on data synchronization and real-time updates.
