Microsoft 365 Endpoint AdministratorDeploy Windows client (25-30%)Hard
An IT administrator is preparing a custom Windows 11 image for deployment using Microsoft Deployment Toolkit (MDT). The image needs to include specific drivers for a new line of laptops and several mandatory applications. The administrator wants to modify the image (.WIM file) directly without performing a full installation and re-capture. Which DISM command-line operation should be used to add drivers and applications to the offline image?
- ADISM /Apply-Image /ImageFile:path\install.wim /Index:1 /ApplyDir:C:\
- BDISM /Add-Driver /Image:C:\Mount /Driver:path\driver.inf
- CDISM /Mount-Image /ImageFile:path\install.wim /Index:1 /MountDir:C:\Mount
- DDISM /Add-Package /Image:C:\Mount /PackagePath:path\app.msi
Show answer & explanationAnswer & explanation
Correct answer: C. DISM /Mount-Image /ImageFile:path\install.wim /Index:1 /MountDir:C:\Mount
To modify a .WIM file directly, it must first be mounted to a local directory using `DISM /Mount-Image`. Once mounted, other DISM commands (like /Add-Driver or /Add-Package) can be used to inject drivers and packages into the offline image.
Why the other options are wrong
- A. This command applies an image to a drive, which is for deployment, not for modifying the image itself.
- B. This command adds a driver, but it requires the image to be already mounted, so it's a subsequent step, not the initial action to enable modification.
- D. This command adds a package (like an update or feature), but it also requires the image to be already mounted.
DISM Image Mounting
The process of making a Windows Imaging Format (.WIM) file accessible for offline servicing by mounting its contents to a local folder, allowing for direct modification.
- Required first step for offline WIM modification.
- Uses `DISM /Mount-Image` command.
- Allows injection of drivers, updates, and packages.
Memory trick: Mount the image, then modify.
