AWS Certified Cloud Practitioner — Question 893

Which design principle is included in the operational excellence pillar of the AWS Well-Architected Framework?

Answer options

• A. Create annotated documentation.
• B. Anticipate failure.
• C. Ensure performance efficiency.
• D. Optimize costs.

Correct answer: B

Explanation

Anticipating failure is a key design principle of the operational excellence pillar, encouraging teams to test failure scenarios and practice recovery procedures. 'Ensure performance efficiency' and 'Optimize costs' align with other pillars of the framework, while 'Create annotated documentation' is a general framework-level design principle rather than one specific to operational excellence.
