Exam AZ-104 topic 1 question 22 discussion

"New-AzVM" is for creating new VMs, not uploading images. "Add-AzImage" does not exist. the correct command is "New-AzImage". "Add-AzImageDataDisk" Adds a data disk to an image object. "Add-AzVhd" seems to be the correct option, sing the it "Uploads a virtual hard disk from an on-premises machine to Azure (managed disk or blob)." (https://docs.microsoft.com/en-us/powershell/module/az.compute/add-azvhd?view=azps-8.3.0)

Correct answer. Example for how you do this: Add-AzVhd -ResourceGroupName $resourceGroup -Destination $urlOfUploadedImageVhd ` -LocalFilePath $localPath

B is corerct

Based on the reference the best option is B: Before you upload a Windows virtual machine (VM) from on-premises to Azure, you must prepare the virtual hard disk (VHD or VHDX). reference https://learn.microsoft.com/en-us/azure/virtual-machines/windows/prepare-for-upload-vhd-image

Uploads a virtual hard disk from an on-premises machine to Azure (managed disk or blob). https://learn.microsoft.com/en-us/powershell/module/az.compute/add-azvhd?view=azps-11.5.0

B is correct

B is correct

The correct PowerShell cmdlet to use for uploading the generalized VM image to Azure is C. Add-AzImage. This cmdlet is used to create a new image in Azure. After generalizing the VM to create an image, you can use the Add-AzImage cmdlet to upload the image to Azure, ensuring that it is available for selection when creating new Azure VMs

"Add-AzImage" can create a new image from managedisk only( -ManagedDiskId parameter is required). That means your VHD image should be uploaded first. Add-AzVHD is used to upload image

Add-AzImage: Purpose: This cmdlet is used to create a managed image from an existing virtual machine (VM) or from a generalized VM image. Usage: You typically use this cmdlet after capturing a VM image, and it creates a generalized or specialized image that you can use to deploy new VMs. Example: Copy Add-AzImage -ImageName "MyImage" -ResourceGroupName "MyResourceGroup" -SourceVirtualMachineId $vm.Id Add-AzVhd: Purpose: This cmdlet is used to copy a virtual hard disk (VHD) file to an Azure Storage Account, making it available for use in creating or configuring VMs. Usage: You might use this cmdlet when you have a VHD file that you want to use to create a new VM, and you need to copy it to Azure storage before attaching it to a VM. Example: Copy Add-AzVhd -LocalFilePath "C:\Path\To\Your\VHD.vhd" -ResourceGroupName "MyResourceGroup" -Destination "https://mystorageaccount.blob.core.windows.net/vhds/MyVHD.vhd"

Add-AzVhd Uploads a virtual hard disk from an on-premises machine to Azure (managed disk or blob). https://learn.microsoft.com/en-us/powershell/module/az.compute/add-azvhd?view=azps-10.4.1&viewFallbackFrom=azps-7.3.0

https://learn.microsoft.com/en-us/azure/devtest-labs/devtest-lab-upload-vhd-using-powershell Check upload a VHD file process: To upload a VHD file by using PowerShell: In a text editor, paste the generated PowerShell script you copied from the Azure portal. Modify the -LocalFilePath parameter of the Add-AZVHD cmdlet to point to the location of the VHD file you want to upload. At a PowerShell command prompt, run the Add-AZVHD cmdlet with the modified -LocalFilePath parameter. The process of uploading a VHD file might be lengthy depending on the size of the VHD file and your connection speed. The correct answer is Add-AzVHD

Vote for B Add-AzVhd https://learn.microsoft.com/en-us/previous-versions/azure/virtual-machines/windows/sa-upload-generalized#start-the-upload

To upload a generalized virtual machine image to Azure for use in creating new Azure VMs, you should use the following PowerShell cmdlet: **C. Add-AzImage** Here's a brief explanation of each option: A. `Add-AzVM` is used to create a new Azure virtual machine, not to upload images. B. `Add-AzVhd` is used to upload a virtual hard disk (VHD) to Azure. It's not used for creating generalized VM images. C. `Add-AzImage` is specifically designed for uploading generalized VM images to Azure. This is the cmdlet you should use for your scenario. D. `Add-AzImageDataDisk` is used to add a data disk to an existing Azure virtual machine, not for uploading generalized images. So, in your case, you should use `Add-AzImage` to upload your generalized VM image to Azure so that it can be used to create new Azure VMs.

Option B is correct
