An organization is designing a highly available application and wants to understand the relationship between AWS Regions and Availability Zones (AZs). Which two statements correctly describe how these global infrastructure components are structured and connected?
- An Availability Zone consists of one or more discrete data centers with redundant power, networking, and connectivity.Answer
- An AWS Region contains multiple, physically separated and isolated Availability Zones.Answer
- CAvailability Zones in different AWS Regions are connected directly via low-latency private fiber links by default.
- DAn Availability Zone represents a large geographic area that contains multiple AWS Regions.
