AWS Certified Cloud Practitioner (CLF-C02) — Question 383

A company is launching a mobile app in the AWS Cloud. The company wants the app's users to sign in through social media identity providers (IdPs).

Which AWS service will meet this requirement?

Answer options

• A. AWS Lambda
• B. Amazon Cognito
• C. AWS Secrets Manager
• D. Amazon CloudFront

Correct answer: B

Explanation

Amazon Cognito provides authentication, authorization, and user management for web and mobile apps, supporting sign-in through social identity providers like Apple, Facebook, Google, and Amazon. AWS Lambda is a serverless compute service, AWS Secrets Manager is used to protect database credentials and API keys, and Amazon CloudFront is a content delivery network, making none of them suitable for user authentication.
