AWS Certified Cloud Practitioner (CLF-C02)Cloud Technology and ServicesEasy
A company's cloud architecture diagram shows a single geographic location containing three physically separate data centers, each with independent power, cooling, and networking, connected by high-bandwidth, low-latency links. What does this diagram represent?
- AA single Availability Zone
- BA single data center with redundant racks
- CA Region containing multiple Availability Zones
- DAn Edge Location
Show answer & explanationAnswer & explanation
Correct answer: C. A Region containing multiple Availability Zones
An AWS Region is a geographic area containing multiple isolated Availability Zones (AZs), each consisting of one or more discrete data centers with independent power and networking, interconnected by high-bandwidth, low-latency links.
Why the other options are wrong
- A. A single Availability Zone is one (or more) data center, not three separate isolated locations within a geography.
- B. A single data center would not have the described independence and isolation of multiple AZs.
- D. Edge Locations are used for content caching (CloudFront), not primary compute infrastructure.
Regions and Availability Zones
An AWS Region is a geographic area containing multiple isolated Availability Zones (AZs), each made up of one or more data centers with independent infrastructure.
- Regions contain 2 or more AZs (most have 3+)
- AZs are physically separated but connected via low-latency links
- Edge locations are separate, used for CloudFront caching
Memory trick: Region = city; AZs = separate buildings in that city.
