AWS Certified Cloud Practitioner — Question 341

Which design principles support the reliability pillar of the AWS Well Architected framework? (Choose two.)

Answer options

• A. Perform operations as code
• B. Enable traceability
• C. Automatically scale to meet demand
• D. Deploy resources globally to improve response time
• E. Automatically recover from failure

Correct answer: C, E

Explanation

The Reliability pillar of the AWS Well-Architected Framework includes design principles such as automatically recovering from failure and scaling horizontally (automatically scaling to meet demand) to prevent capacity issues. In contrast, performing operations as code is part of the Operational Excellence pillar, enabling traceability is a Security principle, and deploying globally for better response times falls under Performance Efficiency.
