Difficulty: EasyCreate and Configure Virtual Machines

A company plans to deploy a web application on virtual machines in the East US region. The application must remain online even if an entire datacenter building experiences a power outage.

Which configuration should be used to protect the virtual machines against datacenter-wide failures?

  1. Deploy the virtual machines across multiple Availability ZonesAnswer
  2. B
    Deploy the virtual machines in an Availability Set
  3. C
    Deploy the virtual machines and configure backups to a Recovery Services vault in a different region
  4. D
    Deploy the virtual machines in a virtual machine scale set and configure an autoscale rule

Answer

Deploying the virtual machines across multiple Availability Zones provides protection against datacenter-wide failures.
Deploying the virtual machines across multiple Availability Zones protects the application against datacenter-wide failures because Availability Zones are physically separate locations within an Azure region, each equipped with independent power, cooling, and networking.

Step-by-Step Solution

1
Identify the scope of redundancy required by the scenario.
The requirement specifies protection against a datacenter-wide power outage.
This helps filter out high availability options that only protect against local rack or server failures.
2
Compare Availability Zones and Availability Sets.
Availability Zones locate virtual machines in physically separate datacenters with independent power and cooling, whereas Availability Sets locate them within the same datacenter.
Understanding the architectural boundaries of each feature determines which one survives a datacenter failure.
3
Select the option that meets the datacenter-wide redundancy requirement.
Deploying across multiple Availability Zones is the correct configuration.
This aligns with the requirement to keep the application online when an entire datacenter building goes down.
