Which of the following statements best describes AWS regions?

AWS regions are geographically distinct locations that host AWS data centers and form the foundational architecture of the global network on which AWS services operate. Each region is designed to be isolated and independent from other regions, providing customers the ability to deploy applications and services in multiple geographic locations. This separation enhances resilience, compliance with local data regulations, and allows for lower latency access to services for users in specific areas.

The reference to AWS regions as the "global infrastructure backbone" underscores their role in enabling users to manage resources effectively across the globe without being limited by physical constraints. Regions serve as a way to organize AWS's global infrastructure, which includes many available services that are accessible from those regions.

Options that focus solely on aspects like backup and recovery or local access miss the broader scope of what AWS regions represent, which is a comprehensive framework for global cloud resource management.
