Which of the following consists of one or more isolated data centers in the same regional area that are interconnected through low-latency networks?
Availability Zone
Edge location
AWS Region
Private networking
Explanations:
An Availability Zone is defined as one or more isolated data centers within a single region, interconnected through low-latency networks. Each Availability Zone is designed to be isolated from failures in other Availability Zones, providing redundancy and high availability.
An Edge location is a site that is designed for caching content and providing low-latency access to users. Edge locations are part of the AWS content delivery network (CDN) and are not data centers connected in a regional area like Availability Zones.
An AWS Region is a geographical area that consists of multiple Availability Zones. While it encompasses these data centers, it does not refer to the isolated data centers themselves or their interconnections directly, but rather the broader geographical context.
Private networking refers to network configurations that allow secure communication within private IP address spaces. It does not specifically describe a set of interconnected data centers like Availability Zones do.
