AWS Certified Cloud Practitioner (CLF-C02) — Question 123

Which responsibility belongs to AWS when a company hosts its databases on Amazon EC2 instances?

Answer options

• A. Database backups
• B. Database software patches
• C. Operating system patches
• D. Operating system installations

Correct answer: D

Explanation

AWS is responsible for the underlying infrastructure, including the hardware and virtualization layer, but when it comes to EC2 instances, the customer is responsible for managing the operating system and applications. Therefore, AWS does not handle operating system installations, making option D correct, while options A, B, and C are responsibilities of the customer.
