Question #741
Which option represents a physical component of the AWS global infrastructure?
AWS Lambda
AWS Region
Amazon API Gateway
AWS CloudFormation
Explanation
The correct answer is B. AWS Region. AWS Regions are physical locations around the world where AWS clusters data centers. Each Region consists of multiple isolated and physically separate Availability Zones (AZs), which are connected via low-latency links. This makes Regions a core physical component of AWS's global infrastructure.
Why other options are incorrect:
- A. AWS Lambda: A serverless compute service, not a physical component.
- C. Amazon API Gateway: A managed service for API management, abstracted from physical infrastructure.
- D. AWS CloudFormation: An infrastructure-as-code tool, not a physical component.
Key Points:
- AWS's physical infrastructure includes Regions, Availability Zones, and Edge Locations.
- Services like Lambda, API Gateway, and CloudFormation are logical/abstracted resources built on top of AWS's physical infrastructure.
Answer
The correct answer is: B
