AWS Certified Cloud Practitioner (CLF-C02) — Question 285

Which of the following are pillars of the AWS Well-Architected Framework? (Choose two.)

Answer options

• A. Resource scalability
• B. Performance efficiency
• C. System elasticity
• D. Agile development
• E. Operational excellence

Correct answer: B, E

Explanation

Performance efficiency and Operational excellence are two of the six official pillars of the AWS Well-Architected Framework, which also includes Security, Reliability, Cost Optimization, and Sustainability. While resource scalability and system elasticity are important architectural concepts, they are not standalone pillars, and Agile development is a software development methodology rather than an AWS framework pillar.
