Answer: Set up an Amazon Cognito identity pool for unauthenticated access and role assumption through unique identity credentials., Define roles: one for authenticated users to access all content, another for unauthenticated users limited to sample content.

Option B is correct because configuring an Amazon Cognito identity pool to allow unauthenticated users enables guest users to access sample content. This configuration also allows the tracking of unauthenticated users who later authenticate if they create an account. Option D is also correct because it involves creating distinct roles for authenticated and unauthenticated users, ensuring that authenticated users have access to all content while guest users can only access sample content. This setup helps in identifying users who have created an account and tracking the transitions from guest to authenticated users.
