Question #1378
Which design principle is associated with the Performance Efficiency pillar according to the AWS Well-Architected Framework?
Test recovery procedures
Experiment more often
Implement a strong identity foundation
Practice cloud financial management
Explanation
The Performance Efficiency pillar of the AWS Well-Architected Framework focuses on using resources efficiently and adapting to changes. One of its core design principles is to Experiment more often (B), as it encourages testing new technologies, architectures, and configurations to achieve optimal performance.
- Why other options are incorrect:
- A. Test recovery procedures: Relates to the Reliability pillar, which ensures systems recover from failures.
- C. Implement a strong identity foundation: Part of the Security pillar, focusing on access control and authentication.
- D. Practice cloud financial management: Belongs to the Cost Optimization pillar, emphasizing cost-effective resource usage.
Key Points: Performance Efficiency prioritizes experimentation (e.g., serverless, auto-scaling) to maintain efficiency as workloads evolve. Memorize the pillars and their associated principles to avoid confusion.
Answer
The correct answer is: B
