Difficulty: MediumCreate and Configure Virtual Machines

An administrator is planning to deploy a new Azure virtual machine named VM-DB1 to host a high-performance database workload. The database requires the use of Azure Ultra Disks for its data volume to achieve sub-millisecond latency. Which of the following configurations must be set during the creation of VM-DB1 to support the use of Ultra Disks? (Select TWO).

  1. Enable Ultra Disk compatibility on the virtual machine.Answer
  2. Deploy the virtual machine into a supported Availability Zone.Answer
  3. C
    Deploy the virtual machine within an Availability Set.
  4. D
    Associate the virtual machine with a Recovery Services vault located in a different Azure region.

Answer

Enable Ultra Disk compatibility on the virtual machine, and deploy the virtual machine into a supported Availability Zone.
To successfully deploy a virtual machine that uses Ultra Disks, you must select an Availability Zone during creation (since Ultra Disks are zonal resources) and enable the 'Ultra Disk compatibility' setting on the virtual machine. This ensures that the VM is placed in a cluster that can support Ultra Disk attachments.

Step-by-Step Solution

1
Identify the storage requirements for the database workload.
The database workload requires Azure Ultra Disks to achieve sub-millisecond latency.
Ultra Disks have specific deployment prerequisites that must be configured during virtual machine provisioning.
2
Determine the availability and placement requirements for Ultra Disks.
The virtual machine must be deployed in a supported Availability Zone within the target region.
Ultra Disks are zonal resources and cannot be associated with virtual machines in Availability Sets.
3
Determine the virtual machine capabilities setting required for Ultra Disks.
Enable the Ultra Disk compatibility capability on the virtual machine.
By default, virtual machines do not have Ultra Disk support enabled, which prevents attaching Ultra Disks as data disks.

Key Concept

Deploying and configuring virtual machines with Ultra Disk compatibility and zonal placement.
