Answer: B. Availability Zone

The correct answer is B. Availability Zone. An Availability Zone (AZ) is a distinct data center within an AWS Region that is designed to be isolated from failures in other Availability Zones. Each AZ has its own power source, networking infrastructure, and connectivity. The purpose of having multiple AZs is to provide fault tolerance and high availability for applications and services hosted in the AWS cloud. By deploying resources across multiple AZs, organizations can ensure that their systems remain operational even if an individual AZ experiences an outage. The other options are incorrect because: A. AWS Region refers to a broader geographical area that contains multiple AZs; C. Edge location is part of AWS's global network of data centers that provide low-latency access to content and services; D. AWS Outposts is a fully managed service that extends AWS infrastructure, services, APIs, and tools to virtually any data center, co-location space, or on-premises facility for a truly consistent hybrid experience.
