Difficulty: MediumCreate and Configure Virtual Machines

An administrator is deploying a new virtual machine named VM1 to host a database. The database workload requires high-performance storage with low latency. The administrator deploys VM1 using the Standard_D2_v3 size. When attempting to attach a Premium SSD managed disk as a data disk to VM1, the administrator finds that Premium SSD is not available. What should the administrator do to enable Premium SSD support for VM1?

  1. Resize VM1 to Standard_D2s_v3.Answer
  2. B
    Convert the OS disk of VM1 from Standard SSD to Premium SSD.
  3. C
    Move VM1 to a different Availability Zone within the same region.
  4. D
    Redeploy VM1 using a Recovery Services Vault restore operation.

Answer

Resize VM1 to Standard_D2s_v3.
Resizing the virtual machine to Standard_D2s_v3 is correct because only Azure virtual machine sizes with the 's' suffix support Premium SSDs and Ultra Disks. The Standard_D2_v3 size does not support premium storage tiers.

Step-by-Step Solution

1
Identify the storage capabilities of the current virtual machine size Standard_D2_v3.
The Standard_D2_v3 size does not support premium storage (Premium SSD or Ultra Disk).
Azure VM sizes require the 's' suffix (e.g., Standard_D2s_v3) to support premium storage.
2
Select a compatible virtual machine size that supports premium storage.
Standard_D2s_v3 is identified as the premium-storage-capable equivalent size.
This size has the same CPU and memory specifications but includes premium storage support.
3
Resize the virtual machine VM1 to Standard_D2s_v3.
VM1 is resized, restarted, and can now successfully attach Premium SSD data disks.
Resizing updates the VM properties to allow premium disk attachments.
