  2. B
    Run sfc /scannow from an elevated command prompt to repair corrupted system assemblies
  3. C
    Use the Programs and Features Control Panel applet to disable User Account Control prompts
  4. D
    Open Computer Management and grant local administrator permissions to the background installation service

Cevap

Execute DISM from an elevated command prompt referencing the installation media source path
The option specifying DISM execution from an elevated prompt with the installation source path is correct. DISM (Deployment Image Servicing and Management) is designed to service Windows images and enable features like .NET Framework 3.5 in offline environments by retrieving source files directly from installation media (e.g., D:\sources\sxs) using the /source parameter.

Adım Adım Çözüm

1
Identify the installation error root cause
The target application requires .NET Framework 3.5, which is an optional Windows feature not enabled by default and unavailable online due to air-gapped environment constraints.
Air-gapped machines cannot query Windows Update servers directly to download feature-on-demand files.
2
Locate the feature payload on the local installation media
The required feature payload resides inside the Side-by-Side folder (sources\sxs) of the mounted Windows installation ISO on drive D:.
Windows installation media stores offline installation files for optional component features.
3
Run DISM command with elevated privileges
Executing 'dism /online /enable-feature /featurename:NetFx3 /all /source:D:\sources\sxs /limitaccess' installs the prerequisite feature offline without requiring internet connectivity.
DISM Services the active operating system image and points directly to local media assets.
