AWS Certified Cloud Practitioner (CLF-C02) — Question 489

Which option is AWS responsible for under the AWS shared responsibility model?

Answer options

• A. Network and firewall configuration
• B. Client-side data encryption
• C. Management of user permissions
• D. Hardware and infrastructure

Correct answer: D

Explanation

Under the AWS shared responsibility model, AWS is responsible for the security 'of' the cloud, which encompasses the physical hardware, facilities, and global infrastructure running the services. Customers are responsible for security 'in' the cloud, which includes configuring firewalls, managing user permissions, and encrypting their own data. Therefore, maintaining hardware and infrastructure is the responsibility of AWS, while the other options are customer responsibilities.
