AWS Certified Cloud Practitioner (CLF-C02) — Question 269

Which of the following is an AWS Well-Architected Framework design principle for operational excellence in the AWS Cloud?

Answer options

• A. Go global in minutes.
• B. Make frequent, small, reversible changes.
• C. Implement a strong foundation of identity and access management
• D. Stop spending money on hardware infrastructure for data center operations.

Correct answer: B

Explanation

Making frequent, small, and reversible changes is a core design principle of the Operational Excellence pillar because it reduces the impact of failures and allows for rapid recovery. The other choices represent principles from different pillars: 'Go global in minutes' belongs to Reliability, 'Implement a strong foundation of identity and access management' belongs to Security, and 'Stop spending money on hardware infrastructure' belongs to Cost Optimization.
