Which of the following is the responsibility of AWS?
A. Setting up AWS Identity and Access Management (IAM) users and groups
B. Physically destroying storage media at end of life
C. Patching guest operating systems
D. Configuring security settings on Amazon EC2 instances
Correct Answer: B
Media storage devices used to store customer data are classified by AWS as Critical and treated accordingly, as high impact, throughout their life-cycles. AWS has exacting standards on how to install, service, and eventually destroy the devices when they are no longer useful. When a storage device has reached the end of its useful life, AWS decommissions media using techniques detailed in NIST 800-88. Media that stored customer data is not removed from AWS control until it has been securely decommissioned.
