Question

Difficulty: MediumConfigure VMs for High Availability

Veloce Systems needs to deploy a two-tier application in the Germany West Central region. The web tier consists of two virtual machines named VM-Web1 and VM-Web2. To meet a 99.95%99.95\% uptime SLA, you plan to deploy the virtual machines in an Availability Set named AvSet-Web.

Which two configuration requirements must be met to deploy this high-availability solution? (Select two.)

  1. The virtual machines must be assigned to AvSet-Web during their creation process.Answer
  2. The virtual machines and AvSet-Web must be deployed in the same Azure region.Answer
  3. C
    The virtual machines can be assigned to AvSet-Web after their initial deployment is complete.
  4. D
    AvSet-Web must be configured to span across multiple Availability Zones in the Germany West Central region.
  5. E
    The virtual machines can be deployed in different Azure regions while sharing the same AvSet-Web.

Answer

The virtual machines must be assigned to the Availability Set during their creation process, and both the virtual machines and the Availability Set must be deployed in the same Azure region.
To configure virtual machines in an Availability Set, the VMs must be associated with the Availability Set during their creation. Once a virtual machine is created, it cannot be added to or removed from an Availability Set. Additionally, an Availability Set is a regional resource, meaning the virtual machines and the Availability Set must reside in the same Azure region.

Step-by-Step Solution

1
Ensure the Availability Set resource exists in the target region prior to deploying the virtual machines.
The Availability Set named AvSet-Web is created in the Germany West Central region.
Virtual machines can only reference an Availability Set that exists in the same region and resource group.
2
Configure the virtual machine deployment settings to associate VM-Web1 and VM-Web2 with AvSet-Web.
VM-Web1 and VM-Web2 are successfully deployed into AvSet-Web.
Azure requires the Availability Set membership to be specified during the VM creation workflow; post-deployment association is not supported.
