Information is pulled from an S3 bucket depending on the user type. Which approaches are recommended to provide access to both user types? (Choose TWO)
 
-- [x] Provide a different access key and secret access key in the application code for registered users and guest users to provide read access to the objects.
-- [x] Use S3 bucket policies to restrict read access to specific IAM users.
-- [ ] Use Amazon Cognito to provide access using authenticated and unauthenticated roles.
