AWS Certified Cloud Practitioner — Question 328

Which of the following are AWS Cloud design principles? (Choose two.)

Answer options

• A. Pay for compute resources in advance
• B. Make data driven decisions to determine cloud architectural design
• C. Emphasize manual processes to allow for changes
• D. Test systems at production scale
• E. Refine operational procedures infrequently

Correct answer: B, D

Explanation

AWS Well-Architected framework design principles recommend testing systems at production scale to simulate real-world workloads and using data to guide architectural decisions. In contrast, AWS encourages a pay-as-you-go consumption model rather than prepaying, automated processes instead of manual ones, and frequent refinement of operational procedures.
