You need to promote Server1 to a domain controller by using install from media (IFM)

Your network contains an Active Directory domain named contoso.com. All domain controllers run Windows
Server 2008 R2. One of the domain controllers is named DCI.
The network contains a member server named Server1 that runs Windows Server 2012.
You need to promote Server1 to a domain controller by using install from media (IFM).
What should you do first?

A.
Create a system state backup of DC1.

B.
Create IFM media on DC1.

C.
Upgrade DC1 to Windows Server 2012.

D.
Run the Active Directory Domain Services Configuration Wizard on Server1.

E.
Run the Active Directory Domain Services Installation Wizard on DC1.

Explanation:
A: Backs up system state data to be restored
B: ???
C: Only valid option. You could install ADDS role on Server 1 and run ADDS configuration wizard andaddDC to
existing domain
D: Need to add ADDS role first
E: Wrong server
Installation from media does not work across different operating system versions. In other words, you must use
a Windows Server 2012 domain controller to generateinstallation media to usefor another Windows Server
2012 domain controller installation.
We can use the Install from media (IFM) option to install an Additional Domain Controller in an existing
domainis the best option such as a branch office scenario where network is slow, unreliable and costly.
IFM will minimize replication traffic during the installation because it uses restored backup files topopulate
theAD DS database. This will significantly reduce the amount of traffic copied over the WAN link.
Things to remember:
If you are deploying your first Domain Controller in the domain, you cannot use IFM. The OS will need to match
the IFM media. (If you create a 2008 R2 IFM, promote a 2008 R2 DC)
If you are creating a DC that will be a Global Catalog Server, create your IFM on a Global Catalog Server.
If you are creating a DC that will be a DNS Server,create your IFM on a DNS Server. If you want to copy the
SYSVOL, the DC on which you generate the installation media and the new DC mustbe at least running
Windows Server 2008 with Service Pack 2 or Windows Server 2008 R2.
Membership of the Domain Admins group is the minimum required to complete IFM.

Media used by the IFM option is created with Windows Server Backup or Ntdsutil.exe from another
existingWindows Server 2012 computer only
You cannot use a Windows Server 2008 R2 or previousoperating system to create media for a Windows
Server 2012 domain controller.
