AWS Certified Cloud Practitioner — Question 73

A company is using an Amazon RDS DB instance for an application that is deployed in the AWS Cloud. The company needs regular patching of the operating system of the server where the DB instance runs.
What is the company's responsibility in this situation, according to the AWS shared responsibility model?

Answer options

• A. Open a support case to obtain administrative access to the server so that the company can patch the DB instance operating system.
• B. Open a support case and request that AWS patch the DB instance operating system.
• C. Use administrative access to the server, and apply the operating system patches during the regular maintenance window that is defined for the DB instance.
• D. Establish a regular maintenance window that tells AWS when to patch the DB instance operating system.

Correct answer: D

Explanation

According to the AWS shared responsibility model, AWS manages the infrastructure while the customer is responsible for managing the software, including the DB instance's operating system. Therefore, the company must establish a maintenance window (option D) for AWS to perform the necessary OS patching. The other options incorrectly suggest that the company should seek administrative access or request AWS to perform actions outside their shared responsibilities.
