Your network contains an Active Directory domain named contoso.com. All domain controllers run
Windows Server 2012 R2.
You pre-create a read- only domain controller (RODC) account named RODC1. You export the settings of
RODC1 to a file named File1.txt.
You need to promote RODC1 by using File1.txt.
Which tool should you use?

A.
The Install-WindowsFeaturecmdlet

B.
The Add-WindowsFeaturecmdlet

C.
TheDism command

D.
TheDcpromo command

E.
The Install-ADDSDomainControllercmdlet

Explanation:
DCPromo is gone, HOWEVER, it is still used for unattend installations using unattended files. This allows
administrators the chance to get used to using powershell commands instead of the unattended file.

NB: http://technet.microsoft.com/en-us/library/jj205467.aspx Install-WindowsFeature Installs one or
more Windows Server roles, role services, or features on either the local or a specified remote serverthat is running Windows Server 2012 R2. This cmdlet is equivalent to and replaces AddWindowsFeature, the cmdlet that was used to install roles, role services, and features in Windows
Server 2008 R2. So the 2 first answers are the same and we only have one choice here…
