AWS Certified Developer Associate DVA-C02 Practice Question
A developer is tasked with enabling a mobile application to authenticate users via third-party social media platforms and subsequently authorize them to directly call cloud services. Which Amazon service should be utilized to fulfill this requirement?
You selected this option
Leverage the Security Token Service to build federated user sessions with external platforms.
You selected this option
Deploy an Amazon Cognito User Pool to directly manage external authentication and access.
You selected this option
Incorporate Amazon QuickSight for identity management and authorization of cloud service API calls.
You selected this option
Implement an Amazon Cognito Identity Pool to federate with external identity providers and acquire temporary credentials for service access.
Amazon Cognito Identity Pools (Federated Identities) give developers the ability to create unique identities for users and federate them with external identity providers, such as social media platforms (Facebook, Google, Amazon, etc.). With these unique identities, the application can secure temporary credentials allowing users to directly interact with cloud service APIs. This is necessary for direct access to cloud services post-authentication. In contrast, User Pools are mainly to create and manage a directory of app users and they don't directly facilitate access to cloud service APIs. While STS is indeed used for temporary credentials, it by itself doesn't cater to social identity provider federation nor provide directory services. AWS QuickSight is a business analytics service and not pertinent to identity management.
