Microsoft Azure Fundamentals — Question 245

What is the most severe failure from which an Azure Availability Zone can be used to protect access to Azure service?

Answer options

• A. a physical server failure
• B. an Azure region failure
• C. a storage failure
• D. an Azure data center failure

Correct answer: D

Explanation

The correct answer is D, as Azure Availability Zones are designed to protect against failures that affect an entire data center, ensuring that services remain available. Options A, B, and C refer to less severe failures that do not warrant the need for Availability Zones, as they can often be resolved without impacting overall service availability.
