You work as a Network Administrator at ABC.com. The network contains a single Active Directory Domain
Services (AD DS) domain named ABC.com. All servers on the network run Windows Server 2008 R2 Service
Pack 1 (SP1).
You plan to migrate all servers to Windows Server 2012. One Windows Server 2008 R2 server is named ABC-
2008DC-1 and is configured as a domain controller for the ABC.com domain. You install Windows Server 2012
on a server, name it ABC-2012DC-1 and join it to the domain. You want to configure ABC-2012DC-1 as a
domain controller using the install from media (IFM) promotion method.
What should you do before attempting to promote ABC-2012DC-1?
A.
You should create a computer account for ABC-2012DC-1 in the domain.
B.
You should upgrade ABC-2008DC-1 to Windows Server 2012.
C.
You should back up the System State of ABC-2008DC-1.
D.
You should install the Active Directory Lightweight Directory Services role on ABC-2008DC-1.
Right because IFM does not work across different operating system versions. If you have a domain controller running Windows Server 2008 R2 and you want to promote a server running Windows Server 2012 or Windows Server 2012 R2 by using IFM, you need to upgrade the domain controller first.
