Microsoft Azure Fundamentals — Question 462

You plan to deploy a service to Azure virtual machines.
You need to ensure that the service will be available if a datacenter fails.
What should you use as part of the virtual machine deployment?

Answer options

• A. availability sets
• B. proximity placement groups
• C. host groups
• D. availability zones

Correct answer: D

Explanation

The correct answer is D, availability zones, as they provide high availability by distributing resources across multiple datacenters. Availability sets (A) protect against hardware failures within a single datacenter but do not ensure availability if the datacenter itself fails. Proximity placement groups (B) optimize the placement of resources for low latency, and host groups (C) are not directly related to high availability.
