A. B. C. D.Correct Answer - C.
Regions consist of 2 or more Availability Zones within a specific geographical area.
These Availability Zones are physically isolated & connected via a low latency redundant link.
Option A is incorrect because Logical Data Center within each region is called an Availability Zones instead of a Data Center.
Option B is incorrect because Edge locations are used by CloudFront CDN to deliver content to users with low latency.
Option D is incorrect because Regional Caches are used by CloudFront which sit between edge locations & origin servers providing additional caching.

AWS Regions are physical locations around the world where AWS provides infrastructure. Each Region consists of multiple Availability Zones (AZs), which are physically separate data centers within a region. These AZs are interconnected with high-bandwidth, low-latency links to provide redundant and low-latency connectivity within the region.
Edge Locations are also part of the AWS global infrastructure but are separate from AWS Regions and AZs. They are endpoints for AWS services that are located closer to end-users to reduce latency and improve performance. Edge Locations are used by AWS CloudFront, AWS's content delivery network (CDN), to cache and distribute content to end-users.
Regional Cache is not a component of the AWS global infrastructure. It is a feature of AWS ElastiCache, which is a web service that makes it easy to deploy and operate an in-memory cache in the cloud.
In summary, while Data Centers, Edge Locations, and Regional Cache are all important components of the AWS ecosystem, Availability Zones within an AWS Region provide low latency redundant connectivity.
