Explanation
In AWS global infrastructure:
- AWS Regions are geographic areas that contain multiple Availability Zones
- Availability Zones (AZs) are physically separate data centers within a Region that contain one or more discrete data centers
- Edge Locations are endpoints for AWS CloudFront (CDN) that cache content closer to users
- Regional Edge Caches are larger CloudFront locations that sit between your origin server and the edge locations
The correct statement is that Availability Zones contain multiple data centers because:
- Each Availability Zone is designed as an isolated failure domain
- AZs consist of one or more discrete data centers with redundant power, networking, and connectivity
- This design provides high availability and fault tolerance within a Region
The other options are incorrect:
- Edge locations do NOT contain AWS Regions
- AWS Regions contain Availability Zones, not Regional edge caches
- Data centers do NOT contain edge locations (edge locations are separate CDN endpoints)
