You have a server named Server1 that runs Windows Server 2012 R2.
You try to install the Microsoft .NET Framework 3.5 Features feature on Server1, but the installation
fails repeatedly.
You need to ensure that the feature can be installed on Server1.
What should you do?

A.
Run the Add-AppxProvisionedPackage cmdlet.

B.
Remove the .NET Framework 4.5 Features feature.

C.
Connect Server1 to the Internet.

D.
Install the Web Server (IIS) server role.

Explanation:
The files needed are no longer available on the local Hard drive. We need to connect the server to
the Internet.
Important to note that when starting with Windows Server 2012 R2 and Windows 8, the feature files
for .NET Framework 3.5 (which includes .NET Framework 2.0 and .NET Framework 3.0) are not
available on the local computer by default. The files have been removed. Files for features that have
been removed in a Features on Demand configuration, along with feature files for .NET Framework
3.5, are available through Windows Update. By default, if feature files are not available on the
destination server that is running Windows Server 2012 R2 R2 Preview or Windows Server 2012 R2,
the installation process searches for the missing files by connecting to Windows Update. You can
override the default behavior by configuring a Group Policy setting or specifying an alternate source
path during installation, whether you are installing by using the Add Roles and Features Wizard GUI
or a command line.
