AWS Certified Cloud Practitioner — Question 302

Which of the following is a recommended design principle of the AWS Well-Architected Framework?

Answer options

• A. Reduce downtime by making infrastructure changes infrequently and in large increments.
• B. Invest the time to configure infrastructure manually.
• C. Learn to improve from operational failures.
• D. Use monolithic application design for centralization.

Correct answer: C

Explanation

"Learn from operational failures" is a fundamental design principle under the Operational Excellence pillar of the AWS Well-Architected Framework, encouraging organizations to treat events as opportunities to improve. In contrast, the framework advises against manual configurations, monolithic architectures, and large, infrequent changes, recommending instead automated infrastructure, decoupled services, and frequent, small, reversible deployments.
