AWS Certified Cloud Practitioner — Question 8

Which design principle is achieved by following the reliability pillar of the AWS Well-Architected Framework?

Answer options

• A. Vertical scaling
• B. Manual failure recovery
• C. Testing recovery procedures
• D. Changing infrastructure manually

Correct answer: C

Explanation

The correct answer is C, as testing recovery procedures ensures that systems can effectively recover from failures, which is a key aspect of reliability. Options A, B, and D do not directly align with the principles outlined in the reliability pillar, as they focus on scaling and manual processes rather than systematic testing and recovery strategies.
