Microsoft Azure Administrator Associate AZ-104 Practice Question

To change the size of an existing Azure VM, you typically need to stop (deallocate) the VM first, then change its size using the Azure portal, PowerShell, or Azure CLI. This process allows you to select a new size that fits your requirements. Changing the VM size while it is running is generally not supported because the VM must be deallocated to switch sizes. Resizing the data disk does not affect the VM's compute size (CPU, memory). Deleting and recreating the VM is unnecessary and could result in data loss unless you've properly backed up and restored the VM.
