Which component of the AWS global infrastructure is made up of one or more discrete data centers that have redundant power, networking, and connectivity?

Explanations:

An AWS Region is a geographical area that consists of multiple Availability Zones, not just data centers.

An Availability Zone is a distinct location within a region that has one or more data centers with redundant power and connectivity.

An Edge location is used for content delivery and caching, not for housing data centers.

AWS Outposts are fully managed services that extend AWS infrastructure and services to on-premises locations, not discrete data centers.
