Question
What are the five pillars of the AWS Well-Architected Framework?
A. Operational Excellence, Elasticity, Scalability, Reliability, Cost Optimization
B. Operational Excellence, Scalability, Reliability, Performance Efficiency, Cost Optimization
C. Operational Excellence, Reliability, Security, Performance Efficiency, Cost Optimization
D. Operational Excellence, Workload Insights, Security, Scalability, Elasticity
Answer
C. Operational Excellence, Reliability, Security, Performance Efficiency, Cost Optimization
Explanation
The correct response option is: Operational Excellence, Reliability, Security, Performance Efficiency, Cost Optimization.
The other responses are incorrect because scalability, elasticity and workload insights are not a separate pillar of the AWS Well-Architected Framework. The are components of the other pillars, but not separate pillars.
The AWS Well-Architected Framework provides architectural best practices across five pillars for designing and operating reliable, secure, efficient, and cost-effective systems in the cloud. The five pillars are:
- Operational Excellence – Focus on running and monitoring systems to deliver business value, and continually improving processes and procedures. Key topics include automating changes, responding to events, and defining standards to manage daily operations.
- Security – Protect information & systems. Key topics include confidentiality and integrity of data, identifying and managing who can do what with privilege management, protecting systems, and establishing controls to detect security events.
- Reliability – Prevent, and quickly recover from failures to meet business and customer demand. Key topics include foundational elements around setup, cross-project requirements, recovery planning, and how we handle change.
- Performance Efficiency – Use IT and computing resources efficiently. Key topics include selecting the right resource types and sizes based on workload requirements, monitoring performance, and making informed decisions to maintain efficiency as business needs evolve.
- Cost Optimization – Run systems to deliver business value at the lowest price point. Key topics include understanding and controlling where money is being spent, selecting the most appropriate and right number of resource types, analyzing spend over time, and scaling to meetbusiness needs without overspending.
So in summary, the correct five pillars are Operational Excellence, Reliability, Security, Performance Efficiency, and Cost Optimization. The other options listed are incorrect, as they include terms like Elasticity, Scalability, and Workload Insights which are not part of the five pillars of the Well-Architected Framework.
