AWS Certified Cloud Practitioner — Question 402

Which of the following are characteristics of AWS Regions and Availability Zones? (Choose two.)

Answer options

• A. Regions bring AWS services to on-premises facilities.
• B. Regions consist of multiple Availability Zones.
• C. An Availability Zone contains several Regions.
• D. Regions are within 100 km (60 miles) of each other.
• E. Regions are located around the world.

Correct answer: B, E

Explanation

AWS Regions are geographically isolated areas distributed globally, and each Region is designed to contain multiple, redundant Availability Zones to ensure high availability and fault tolerance. On-premises integration is achieved through services like AWS Outposts rather than Regions themselves, and Availability Zones exist within Regions, not vice versa. Additionally, AWS Regions are typically separated by vast distances, far exceeding 100 km, to mitigate the impact of regional disasters.
