AWS Certified Developer Associate DVA-C02 Practice Question

Cognito Identity Pools, also known as federated identities, enable developers to set up unique identities for users and authenticate them for secure access to other cloud services. This includes both authenticated and unauthenticated (guest) access. They allow the creation of temporary credentials that allow users to assume roles with limited permissions directly, satisfying the requirement for access by both types of users. On the contrary, User Pools are primarily used as a user directory to manage user sign-up and sign-in functions for application users. Hence, for scenarios that require support for guest users and providing direct access to cloud services, the Identity Pools feature of Cognito is the appropriate solution.
