AWS Certified Cloud Practitioner — Question 282

A company stores data in an Amazon S3 bucket.

Which task is the responsibility of AWS?

Answer options

• A. Configure an S3 Lifecycle policy.
• B. Activate S3 Versioning.
• C. Configure S3 bucket policies.
• D. Protect the infrastructure that supports S3 storage.

Correct answer: D

Explanation

Under the AWS Shared Responsibility Model, AWS is responsible for the security 'of' the cloud, which includes protecting the global infrastructure, hardware, and virtualization layer that hosts Amazon S3. In contrast, managing data-level controls such as S3 Lifecycle policies, S3 Versioning, and S3 bucket policies is the customer's responsibility as part of security 'in' the cloud.
