CLF-C02 practice question: Well-Architected Framework (4 of 4)
Cloud Concepts A free question from our original CLF-C02 practice exam. Try it, then open the answer to see why each option is right or wrong.
A team plans to try different instance types and storage configurations regularly, to consume advanced technologies such as machine learning as managed services instead of building that expertise itself, and to choose databases based on how its data will be accessed. Which Well-Architected pillar's design principles is the team following?
Choose one answer.
- AA. Cost Optimization
- BB. Reliability
- CC. Operational Excellence
- DD. Performance Efficiency
Show the answer and explanation
Answer: D
- A. Wrong: Cost Optimization principles focus on cloud financial management, adopting a consumption model and attributing spend, not on experimenting to find the best-performing resources.
- B. Wrong: Reliability principles focus on recovering from failure, testing recovery and scaling horizontally.
- C. Wrong: Operational Excellence principles focus on operations as code, small reversible changes and learning from failures.
- D. Right: Correct. 'Experiment more often', 'democratize advanced technologies' and 'consider mechanical sympathy' are Performance Efficiency design principles.
Explanation
The Performance Efficiency pillar is about using computing resources efficiently to meet requirements. Its design principles are: democratize advanced technologies, go global in minutes, use serverless architectures, experiment more often, and consider mechanical sympathy (choosing the approach that fits how data is accessed). It is easy to confuse with Cost Optimization, which is about avoiding unnecessary spend.
