Question #1105
Which pillar of the AWS Well-Architected Framework emphasizes selecting the most appropriate resource types and sizes to meet workload requirements efficiently?
Reliability
Operational excellence
Performance efficiency
Sustainability
Explanation
The Performance Efficiency pillar of the AWS Well-Architected Framework emphasizes selecting the most appropriate resource types and sizes (e.g., compute instances, storage solutions, databases) to meet workload requirements efficiently. It ensures workloads can scale and adapt to changes in demand while optimizing performance.
Why other options are incorrect:
- A. Reliability: Focuses on fault tolerance, recovery, and ensuring workloads operate as intended, not resource selection.
- B. Operational Excellence: Deals with operational processes, automation, and continuous improvement, not resource optimization.
- D. Sustainability: Targets minimizing environmental impact through energy-efficient practices, not direct resource sizing or type selection.
Key Point: Performance Efficiency includes evaluating AWS services (e.g., EC2 instance types, S3 storage classes) to ensure cost-effective and scalable solutions.
Answer
The correct answer is: C
