AWS Certified Cloud Practitioner (CLF-C02) — Question 471

According to the AWS shared responsibility model, which task is the customer's responsibility?

Answer options

• A. Maintaining the infrastructure needed to run AWS Lambda
• B. Updating the operating system of Amazon DynamoDB instances
• C. Maintaining Amazon S3 infrastructure
• D. Updating the guest operating system on Amazon EC2 instances

Correct answer: D

Explanation

Under the AWS shared responsibility model, AWS is responsible for the security 'of' the cloud, which includes managing the infrastructure for services like AWS Lambda, Amazon DynamoDB, and Amazon S3. The customer is responsible for security 'in' the cloud, which includes managing and patching the guest operating system on Infrastructure as a Service (IaaS) resources like Amazon EC2. Therefore, updating the EC2 guest operating system is a customer responsibility, while the other tasks are managed by AWS.
