AWS Certified Cloud Practitioner — Question 293

An Availability Zone consists of:

Answer options

• A. one or more data centers in a single location.
• B. two or more data centers in multiple locations.
• C. one or more physical hosts in a single data center.
• D. two or more physical hosts in multiple data centers.

Correct answer: A

Explanation

An Availability Zone (AZ) is defined as one or more discrete data centers with redundant power, networking, and connectivity within a specific region. Options B and D are incorrect because an AZ is isolated to a single location rather than being distributed across multiple regions or distinct locations. Option C is incorrect because an AZ represents entire data centers, not just individual physical hosts.
