AWS Certified Cloud Practitioner — Question 429

Which duty is a responsibility of AWS under the AWS shared responsibility model?

Answer options

• A. Identity and access management
• B. Server-side encryption (SSE)
• C. Firewall configuration
• D. Maintaining physical hardware

Correct answer: D

Explanation

Under the AWS shared responsibility model, AWS is solely responsible for the security 'of' the cloud, which includes managing and maintaining the physical hardware, global infrastructure, and facilities. In contrast, security 'in' the cloud is the customer's responsibility, which encompasses tasks like configuring firewalls, managing identity and access, and implementing encryption. Therefore, maintaining physical hardware is an AWS responsibility, while the other choices are customer duties.
