Multiple Choice

Developers have requested a new Amazon Redshift cluster so they can load new third-party marketing data. The new cluster is ready and the user credentials are given to the developers. The developers indicate that their copy jobs fail with the following error message: "Amazon Invalid operation: S3ServiceException:Access Denied,Status 403,Error AccessDenied." The developers need to load this data soon, so a database specialist must act quickly to solve this issue. What is the MOST secure solution?

• C) Create a new IAM role with read-only access to the Amazon S3 bucket with the assume role action. Add this role to the developer IAM user ID used for the copy job that ended with an error message.
• D) Create a new IAM user with access keys and a new role with read-only access to the Amazon S3 bucket. Add this role to the Amazon Redshift cluster. Change the copy job to use the access keys created.
