An administrator is managing an Azure virtual machine named VM1 in the East US region. VM1 is currently configured with the Standard_D2s_v3 size and uses a Premium SSD disk for its operating system. To reduce monthly running costs, you attempt to resize VM1 to the Standard_D2_v3 size. The resize operation fails. What is the cause of this failure?
- The Standard_D2_v3 size does not support Premium SSD storage.Cevap
- BVM1 must be added to an Availability Set before it can be resized to a size in a different performance tier.
- CThe Recovery Services Vault configured to back up VM1 is located in a different Azure region, which blocks hardware configuration updates.
- DThe administrator lacks data-plane permissions, such as the Storage Blob Data Reader role, on the storage account hosting the virtual machine's OS disk.
Cevap
The Standard_D2_v3 size does not support Premium SSD storage.
The correct answer is correct because Azure virtual machine sizes without the 's' suffix (such as Standard_D2_v3) do not support Premium SSD storage. If a virtual machine currently has a Premium SSD disk attached, attempting to resize it to a size that only supports Standard storage will fail. To resolve this, you must change the disk type to Standard SSD or Standard HDD before resizing.
