The 3rd command should be "Dismount-WindowsImage". As you can check on the links provided, "Save-WindowsImage" has no -save option but "Dismount-WindowsImage" has this option https://docs.microsoft.com/en-us/powershell/module/dism/save-windowsimage?view=win10-ps https://docs.microsoft.com/en-us/powershell/module/dism/dismount-windowsimage?view=win10-ps

Incorrect. Save-WindowsImage does NOT have the -save parameter. Correct answer is Dismount for 3rd option. Save-WindowsImage -Path <String> [-CheckIntegrity] [-Append] [-LogPath <String>] [-ScratchDirectory <String>] [-LogLevel <LogLevel>] [<CommonParameters>]

Save-WindowsImage DOES NOT HAVE A "-Save" parameter. There can not be correct answer for 3rd step.... Dismount-WindowsImage is correct. -Path <String> [-CheckIntegrity] [-Append] [-LogPath <String>] [-ScratchDirectory <String>] [-LogLevel <LogLevel>] [<CommonParameters>]

I guess the answer is "SAVE" not " DISMOUNT"... Because, if you see the 3rd part carefully, it asked for "SAVE" not " SAVE and DISMOUNT" . the SAVE option will only save the changes you made in image but wont dismount it. But the DISMOUNT option will save the changes and dismount the image. For the questions demand, i will pick SAVE instead of DISMOUNT. PS C:\> Save-WindowsImage -Path "c:\offline" This command saves the servicing changes made to the Windows image mounted to c:\offline. It does not unmounts the image. PS C:\> Dismount-WindowsImage -Path "c:\offline" -Save This command dismounts the Windows Image mapped to c:\offline and saves any changes that were made while servicing the image. https://docs.microsoft.com/en-us/powershell/module/dism/save-windowsimage?view=win10-ps https://docs.microsoft.com/en-us/powershell/module/dism/dismount-windowsimage?view=win10-ps

The question says: "You need to APPLY a cumulative update", it doesn't say you need to save. So, based on the given options, Dismount-WindowsImage makes sense.

Save-WindowsImage cmdlet applies the servicing changes made to a mounted image to its WIM or VHD file without unmounting it. 3rd command is correct.

Save-WindowsImage cmdlet is incorrect. -save is not used in de save-windowsimage cmdlet. https://docs.microsoft.com/en-us/powershell/module/dism/save-windowsimage?view=win10-ps Meaning Dismount is correct.

That's because the "Save-WindowsImage" cmdlet doesn't need a -save switch, it's sole function is save servicing changes without dismounting. So technically it is correct, the issue then becomes whether you need to dismount the image. Personally i think you and others are right, if I were doing this then I would Dismount -save to save and dismount at the same time but knowing MS questions I'm going to go with the save option as it is does what the question asks and I feel that will get me the mark. Fortunately you'll still get two points out of three either way. I just wish MS would give a point for any solution that accomplishes the goal unless it's wrong, not just the solution they want you to use.

Very true; however, the provided command does have the -save commend making it invalid. Correct answer is Dismount for third option.
