Your network contains an Active Directory domain named contoso.com. The domain
contains several domain controllers. The domain controllers run either Windows Server 2012 or Windows Server 2008 R2.

The domain functional level is Windows Server 2008 R2. The forest functional level is Windows Server 2008.

using the following methods:
/ Enable-ADOptionalFeature Active Directory module cmdlet (This is the recommended method.) / Ldp.exe
