Difficulty: EasyCreate and Configure Virtual Machines

You are creating a new Azure virtual machine (VM). You need to configure the VM's infrastructure options to protect the hosted application from datacenter-wide power, cooling, or network failures within an Azure region. Which availability option should you select during the VM creation process?

  1. A
    Availability Sets
  2. Availability ZonesAnswer
  3. C
    A Recovery Services Vault in a different region
  4. D
    A Basic Load Balancer backend pool

Answer

Availability Zones
Selecting Availability Zones ensures that the virtual machine is deployed in physically separate datacenters within an Azure region. Each zone has independent power, cooling, and networking, protecting the application from datacenter-wide failures.

Step-by-Step Solution

1
Analyze the requirement for VM infrastructure redundancy.
The requirement specifies protection against datacenter-wide failures within an Azure region.
Datacenter-wide failures require physical isolation between the nodes within the region.
2
Evaluate the capability of Availability Zones.
Availability Zones place VMs in physically separate datacenters (each with independent power, cooling, and network) within the same region.
This aligns exactly with the requirement for protection against datacenter-wide failures.
3
Identify why alternative options like Availability Sets are insufficient.
Availability Sets distribute VMs across fault and update domains within a single datacenter, failing to protect against datacenter-wide outages.
Ensures the correct infrastructure option is selected.

Key Concept

Availability Zones provide infrastructure redundancy and high availability within a region by placing VMs in physically separate datacenters.
