Answer: Availability Zones contain multiple data centers.
## 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)
