Your network contains an Active Directory domain named contoso.com.
The domain contains two domain controllers.
The domain controllers are configured as shown in the following table.

In the perimeter network, you install a new server named Server1 that runs Windows Server 2012.
Server1 is in a workgroup.
You need to perform an offline domain join of Server1 to the contoso.com domain. What should you do first?

A.
Run the djoin.exe command.

B.
Run the dsadd.exe command.

C.
Transfer the PDC emulator role to DC1.

D.
Transfer the infrastructure master role to DC1.

Explanation:
There do not appear to be any requirements on operations master roles for this specific requirement.

moreover, ODJ is available on both 2008R2 and 2012
and if there was to deal with a FSMO, RID would be concerned as it’s needed to create an AD object (inthis
case, creating the computer account) but it’s not an answer here.
so i’ll keep djoin even if i’m not 100% sure
