Correct Answer: D

Explanation: You do not need to rotate IAM Role Access Keys because AWS will do it on your behalf. Through the use of the security credentials linked to the role, the application is given access to the actions and resources that you have defined for the role. We automatically rotate these temporary security credentials. At least five minutes before the old credentials expire, we make fresh credentials available.
