AWS Certified Cloud Practitioner — Question 898

Which of the following are aspects of the AWS shared responsibility model? (Choose two.)

Answer options

• A. Configuration management of infrastructure devices is the customer's responsibility.
• B. For Amazon S3, AWS operates the infrastructure layer, the operating systems, and the platforms.
• C. AWS is responsible for protecting the physical cloud infrastructure.
• D. AWS is responsible for training the customer's employees on AWS products and services.
• E. For Amazon EC2, AWS is responsible for maintaining the guest operating system.

Correct answer: B, C

Explanation

AWS is responsible for the security 'of' the cloud, which includes protecting physical data centers (C) and managing the infrastructure, OS, and platform layers for abstract services like Amazon S3 (B). Customers are responsible for security 'in' the cloud, which includes configuring their own guest operating systems on Amazon EC2 (making E incorrect) and managing their own configuration and staff training (making A and D incorrect).
