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

C. Add-AzImage Explanation: Since you generalized the VM to create an image, you need to upload it to Azure as a managed image. Add-AzImage is the PowerShell cmdlet used to add a VM image to Azure, making it available for creating new VMs. Why Not the Other Options? A. Add-AzVM → This is used to create a VM, not to upload an image. B. Add-AzVhd → Used for uploading a VHD file, but does not create an image from it. D. Add-AzImageDataDisk → Used to add a data disk, not a VM image.

By using Add-AzImage, you ensure that the image is available for selection when creating new Azure VMs.

To upload a generalized VM image and make it available for deployment in Azure, we need to use Add-AzImage. This cmdlet allows to register a VM image in Azure Compute Gallery (formerly Shared Image Gallery) or in the subscription's image repository. After we generalize the reference VM using Sysprep (Windows), we need to follow these steps: 1- Capture the image: * For Azure VMs, use Save-AzVmImage. * For on-premises VMs, create a VHD and upload it. 2- Upload the VHD to an Azure Storage account. 3- Create an image using Add-AzImage: $imageConfig = New-AzImageConfig -Location "EastUS" -SourceUri "https://yourstorageaccount.blob.core.windows.net/vhds/your-image.vhd" -OsType Windows Add-AzImage -Image $imageConfig -ResourceGroupName "YourResourceGroup" This ensures that the image is available for VM creation in Azure.

It is Add-AzVhd. This is one of the question in the Microsoft Learn mock test

B is correct

To upload a generalized VM image to Azure and make it available for creating new VMs, you would use a combination of the following PowerShell cmdlets: Add-AzVhd: This cmdlet uploads the generalized VHD file (your image) to an Azure storage account. Add-AzImage: This cmdlet creates a managed image from the uploaded VHD file, making it available for creating new Azure VMs.

for me B is correct

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"
