AWS Certified Cloud Practitioner — Question 863

A company wants to use the AWS Cloud to define its entire infrastructure as code. The company wants to limit human error and activate consistent responses to events.

Which pillar of the AWS Well-Architected Framework does this plan support?

Answer options

• A. Security
• B. Operational excellence
• C. Cost optimization
• D. Reliability

Correct answer: B

Explanation

The Operational Excellence pillar focuses on running and monitoring systems to deliver business value, and continually improving supporting processes and procedures, which includes defining infrastructure as code and automating responses to events to reduce human error. While Security, Cost Optimization, and Reliability are important pillars, they do not primarily focus on the operational practices of automating infrastructure deployment and incident response procedures.
