AWS Certified Developer Associate Practice Test 6

Correct answer - "Cognito User Pools" : After successfully authenticating a user, Amazon Cognito issues JSON web tokens (JWT) that you can use to secure and authorize access to your own APIs, or exchange for AWS credentials.

Incorrect:

"API Gateway" - If you are processing tokens server-side and using other programming languages not supported in AWS it may be a good choice other than that go with a service already providing the functionality

"Cognito Identity Pools" - A way to authorize your users to use the various AWS services vs authorization in your application

"Cognito Sync" - You can use it to synchronize user profile data across mobile devices and the web without requiring your own backend
