AWS Certified Cloud Practitioner — Question 659

Which pillar of the AWS Well Architected Framework includes the design principle of defining workloads, applications, and infrastructure as code (IaC)?

Answer options

• A. Operational excellence
• B. Reliability
• C. Performance efficiency
• D. Security

Correct answer: A

Explanation

The Operational Excellence pillar focuses on running and monitoring systems to deliver business value, and its key design principle is to 'perform operations as code' by defining workloads and infrastructure as IaC. While other pillars benefit from IaC, this specific design principle is officially anchored in the Operational Excellence pillar. The other options represent different pillars of the framework with their own distinct design principles.
