Difficulty: MediumCreate and Configure Virtual Machines

You are planning to deploy a new Azure virtual machine named VM1 to host a database workload. The database requires extremely high I/O throughput and sub-millisecond latency. You decide to use Ultra Disk storage for the database data. Which two settings must you configure during the creation of VM1 to support the attachment of Ultra Disks? (Select two.)

  1. Enable Ultra Disk compatibility in the disk configuration.Answer
  2. Deploy the virtual machine in a specific Availability Zone.Answer
  3. C
    Place the virtual machine in an Availability Set.
  4. D
    Select Ultra Disk as the operating system (OS) disk type.

Answer

To support Ultra Disks, you must deploy the virtual machine in a specific Availability Zone and enable Ultra Disk compatibility in the disk configuration.
To successfully deploy an Azure virtual machine with Ultra Disks, you must configure two key settings during creation. First, you must enable Ultra Disk compatibility in the virtual machine disk configuration settings. Second, because Ultra Disks are zonal resources, the virtual machine must be deployed in a specific Availability Zone.

Step-by-Step Solution

1
Determine the availability options for the virtual machine.
Identify that Ultra Disks require the virtual machine to be deployed in an Availability Zone.
Ultra Disks are zonal resources and do not support Availability Sets.
2
Configure the disk capabilities for the virtual machine.
Enable the 'Ultra Disk compatibility' setting under the Advanced disk configuration.
Ultra Disks cannot be attached to a virtual machine unless compatibility is explicitly enabled during virtual machine creation.
3
Select the correct disk type for the operating system (OS) disk.
Ensure the OS disk uses Standard HDD, Standard SSD, or Premium SSD.
Operating system (OS) disks do not support the Ultra Disk type.

Key Concept

Configuring virtual machine storage and availability settings during creation to support Ultra Disks.
