AWS Certified Cloud Practitioner — Question 676

According to the AWS shared responsibility model, who is responsible for the virtualization layer down to the physical security of the facilities in which AWS services operate?

Answer options

• A. It is the sole responsibility of the customer
• B. It is the sole responsibility of AWS
• C. It is a shared responsibility between AWS and the customer
• D. The customer's AWS Support plan tier determines who manages the configuration

Correct answer: B

Explanation

Under the AWS shared responsibility model, AWS is responsible for the security 'of' the cloud, which encompasses the physical infrastructure, facilities, hardware, and the virtualization hypervisor. Customers are responsible for security 'in' the cloud, meaning support plans or shared duties do not shift the ownership of the underlying physical and virtualization infrastructure away from AWS.
