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

You discover that when you run Group Policy Results from Group Policy Management, the settings from site-linked Group Policy objects (GPOs) fail to appear in
the results.
You need to ensure that the settings from site-linked GPOs appear in the results.

A.
Run adprep on DC3 by using Windows Server 2012 R2 installation media.

B.
Transfer the infrastructure master role to DC3.

C.
Upgrade DC2 to Windows Server 2012 R2.

D.
Run adprep on DC1 by using Windows Server 2003 installation media.

Explanation:
In this scenario a Windows 2012 server has been added to a Windows 2003 network.

Note:
* Before adding your new Windows 2012 Domain Controller, or attempting to perform an inplace upgrade of an existing Windows 2008 or 2008 R2 DC, you must
make sure that the Schema is upgraded to support your new Windows 2012 DC, and that you prepare each domain where you plan to install Windows 2012 DCs.
To do this we can use the ADPREP.exe tool found in the support\\adprep folder on your installation media.
* Starting with Windows 2012 there is only one version of ADPREP available, and that is a 64-bit version.
* Adprep is the utility–included in the OS installation media–that performs several crucial functions to upgrade AD to support that OS. The utility has three major
options: /forestprep, /domainprep, and /rodcprep. The /forestprep option runs first, extending the AD schema with new object and attribute classes that the new AD
version needs.
The /domainprep option creates new well-known objects in AD, App1ies security changes, and miscellaneous other bits. Finally, /rodcprep makes forest-wide
security changes to allow read-only domain controller (RODC) functionality. The Windows Server 2012 R2 version of adprep.exe can run on any server that runs a
64- bit version of Windows Server 2008 or later. Reference: How to add a Windows Server 2012 R2 domain controller to an existing Windows 2008 domain

    There are some major problems with this question. First of all, the table show that the environment has a 2012 Domain Controller. This means that when they installed the 2012 server and added AD DS and promoted to a DC within an existing forest, it would have already run the adprep automatically because it would know that it is being added to a 2003 forest. It doesn’t give you an option to skip the ADprep when adding a server 2012 domain controller to a a lower environment. From this, we can rule out that A and D cannot be correct. C cannot be correct because you cannot have an in-place upgrade from 2003 to 2012. Therefore, the only answer left would be B.

    I don’t know why the answer is B so if someone could explain or explain why it is something else, please reply.

      adprep /domainprep /gpprep doesn’t run automatically when installing/promoting a 2012 DC.
      needs to run on infrastructure master.
      guess those 2003 servers are not 64bit.
      Only answer possible to me seems B…

      All of the questions I have seen so far assume that any OS before 2008R2 is not 64 bit even if it had the option to be

      When you automatically prepare an existing domain for Windows Server 2012 by using Windows Server 2012 Server Manager or the Install-AddsDomainController Windows PowerShell cmdlet, Group Policy preparation is not performed. Additionally, the following output is displayed very briefly when you use Install-AddsDomainController:

      Adprep successfully updated the forest-wide information.

      Adprep successfully updated the domain-wide information.

      The new cross domain planning functionality for Group Policy, RSOP Planning Mode, requires file system and Active Directory Domain Services permissions to be updated for existing Group Policy Objects (GPOs).

      Note This output is not visible when you install Active Directory Domain Services (AD DS) by using Server Manager, and the output is not logged.

      Although other adprep.exe commands are run automatically as part of the AD DS installation process beginning with Windows Server 2012, the adprep /domainprep /gpprep command is not run automatically. If the command has never been run in your environment, you may need to run it separately. For more information, see KB article 2737129.

        TL;DR: Technically you have to do what is stated in the selected answer, however the command is 64bit only and so you can’t run it on a server that isn’t 64-bit, and you have to run it with a switch that requires you to be running it from the Infrastructure Master.

        And so you have to make the only available server the Infrastructure Master and then run the command. The question is asking what to do first not what to do to fix the issue, you have to move the FSMO role over.

    I agree with John, adprep /domainprep /gpprep needs to be run on the infrastructure master, so you will need to either upgrade or move the role, moving the role is the easiest.
