AWS Certified Cloud Practitioner — Question 462

What is an Availability Zone?

Answer options

• A. A location where users can deploy compute storage, database and other select AWS services where no AWS Region currently exists
• B. One or more discrete data centers with redundant power, networking and connectivity
• C. One or more clusters of servers where new workloads can be deployed
• D. A fast content delivery network (CDN) service that securely delivers data videos applications and APIs to users globally

Correct answer: B

Explanation

An Availability Zone (AZ) consists of one or more isolated data centers designed with redundant power, networking, and connectivity within an AWS Region. Option D describes a Content Delivery Network like Amazon CloudFront, while Option A refers to AWS Local Zones. Option C is too generic and does not capture the high-availability infrastructure design of an AZ.
