AWS Certified Developer Associate DVA-C02 Practice Question
An application developer is tasked with enabling authentication through social media logins for a new mobile app and subsequently permitting access to specific cloud storage and database services on behalf of the authenticated user. Which Amazon Cognito feature should the developer leverage to achieve these requirements?
Amazon Cognito User Pools
Amazon Cognito Identity Pools
IAM roles with trust relationships
External identity provider integration with a token broker service
The developer should leverage Amazon Cognito Identity Pools to meet the requirements. Identity Pools support federated sign-in with social identity providers and exchange the resulting identity information for temporary, limited-privilege AWS credentials. These credentials allow direct, fine-grained access to services such as Amazon S3 or Amazon DynamoDB. By contrast, User Pools primarily provide user directory and authentication capabilities and do not directly issue AWS service credentials without an identity pool.
