AWS Certified Cloud Practitioner — Question 849

What is a customer responsibility under the AWS shared responsibility model when using AWS Lambda?

Answer options

• A. Maintenance of the underlying Lambda hardware.
• B. Maintenance of the Lambda networking infrastructure.
• C. The code and libraries that run in the Lambda functions.
• D. The Lambda server software.

Correct answer: C

Explanation

Under the AWS shared responsibility model for serverless services like AWS Lambda, AWS manages the physical infrastructure, virtualization layer, operating system, and execution environment. The customer remains responsible for the code they write, the configuration of their functions, and any third-party libraries they import. Consequently, managing the application code and libraries is a customer responsibility, while AWS handles the hardware, networking, and server software.
