Answer: Employ Amazon Cognito to grant unauthenticated users limited resource access via IAM roles.
The correct answer is D. Amazon Cognito allows you to create unique identities for users of your application and assign permissions to these identities using IAM roles. By using Cognito's unauthenticated identities (also known as guest users), you can grant limited AWS resource access to users without requiring them to log in. This approach is secure, scalable, and does not require the management of user credentials. Options A, B, and C do not provide the same level of efficiency and security for unauthenticated user access.
