The correct answer is C. Changing the virtual machine size only. Changing the VM size (D2s_v4 to D4s_v4) requires deallocating (stopping) the VM, which constitutes downtime. Azure must move the VM to different underlying hardware to accommodate the new size. In contrast, both detaching a data disk and attaching a new standard SSD are…
Question
You have an Azure virtual machine named VM1 that runs Windows Server and has the following configurations:
Size: D2s_v4 Operating system disk: 127-GiB standard SSD Data disk 128-GiB standard SSD Virtual machine generation: Gen 2 You plan to perform the following changes to VM1:
Change the virtual machine size to D4s_v4. Detach the data disk. Add a new standard SSD. Which changes require downtime for VM1?
Options
- ADetaching the data disk only and adding a new standard SSD.
- BDetaching the data disk only.
- CChanging the virtual machine size only.
- DAdding a new standard SSD only.

Explanation
Changing the VM size (D2s_v4 to D4s_v4) requires deallocating (stopping) the VM, which constitutes downtime. Azure must move the VM to different underlying hardware to accommodate the new size. In contrast, both detaching a data disk and attaching a new standard SSD are hot-swap operations supported on Gen 2 VMs running Windows Server - they can be performed while the VM is running without any downtime. Therefore, only the size change requires downtime.
