Difficulty: EasyCreate and Configure Virtual Machines

You plan to deploy a new Azure virtual machine. You need to ensure the virtual machine is protected against power, cooling, or network failures that affect an entire datacenter building within an Azure region. Which availability option should you configure when creating the virtual machine?

  1. A
    Availability Sets
  2. Availability ZonesAnswer
  3. C
    Virtual Machine Scale Set autoscale policy
  4. D
    Isolated App Service Plan

Answer

Availability Zones
Availability Zones provide physically separate locations within an Azure region, which protects virtual machine deployments from datacenter-level outages such as power, cooling, or networking issues.

Step-by-Step Solution

1
Determine the scope of failure protection needed.
The requirement is to protect against failures affecting an entire datacenter building.
This tells us that logical separation within a single datacenter is insufficient, and physically separate locations are required.
2
Compare availability features available during virtual machine creation.
Availability Zones represent physically separate datacenters within an Azure region, each with independent power, cooling, and networking. Availability Sets distribute virtual machines across physical servers, storage units, and network switches within a single datacenter.
We must select the feature that maps to physical building-level redundancy.
3
Select the correct option that matches the physical redundancy requirement.
Select Availability Zones.
This guarantees that the virtual machine will be hosted in a separate physical building from resources in other zones, satisfying the requirement.

Key Concept

Distinguishing between Availability Zones (physical datacenter-level redundancy) and Availability Sets (rack-level redundancy inside a single datacenter) when creating Azure Virtual Machines.
