AWS Certified Cloud Practitioner — Question 475

Which activity is a customer responsibility in the AWS Cloud according to the AWS shared responsibility model?

Answer options

• A. Ensuring network connectivity from AWS to the internet
• B. Patching and fixing flaws within the AWS Cloud infrastructure
• C. Ensuring the physical security of cloud data centers
• D. Ensuring Amazon EBS volumes are backed up

Correct answer: D

Explanation

Under the AWS shared responsibility model, AWS is responsible for the security 'of' the cloud, which includes physical data center security, infrastructure patching, and global network connectivity. The customer is responsible for security 'in' the cloud, which encompasses managing their own data and configurations, such as backing up Amazon EBS volumes. Therefore, creating and maintaining backups of EBS volumes is entirely the customer's duty.
