What types of identities do Amazon Cognito identity pools support?
They support both authenticated and unauthenticated identities.
They support only unauthenticated identities.
They support neither authenticated nor unauthenticated identities.
They support only authenticated identities.
Explanations:
Amazon Cognito identity pools support both authenticated identities (users who have logged in via various identity providers) and unauthenticated identities (users who have not logged in). This allows developers to manage access for a range of user scenarios.
This option states that only unauthenticated identities are supported, which is not true. Cognito also supports authenticated identities.
This option claims that neither authenticated nor unauthenticated identities are supported, which is false. Cognito explicitly supports both types of identities.
This option suggests that only authenticated identities are supported, ignoring the capability for unauthenticated identities, which is a key feature of identity pools.
I rate that the answer is:
They support both authenticated and unauthenticated identities.
