You need to configure SERVER1 as a new domain controller in a new forest named contoso.test

***
Your network contains an Active Directory domain named contoso.com.
The domain contains Domain Controllers that run either Windows Server 2003, Windows Server 2008 R2, or
Windows Server 2012.
You plan to implement a new Active Directory forest. The new forest will be used for testing and will be isolated
from the production network.
In the test network, you deploy a server named SERVER1 that runs Windows Server 2012.
You need to configure SERVER1 as a new domain controller in a new forest named contoso.test.
The solution must meet the following. Select two options below.

A.
There is no need to set the Forest Functional Level.

B.
Set Forest Functional Level to Windows 2003.

C.
Set Forest Functional Level to Windows 2008

D.
Set Forest Functional Level to Windows 2008 R2.

E.
Set Forest Functional Level to Windows 2012.

F.
There is no need to set the Domain Functional Level.

G.
Set Domain Functional Level to Windows 2003.

H.
Set Domain Functional Level to Windows 2008

I.
Set Domain Functional Level to Windows 2008 R2.

J.
Set Domain Functional Level to Windows 2012.

Explanation:
When you deploy AD DS, set the domain and forest functional levels to the highest value that your environment
can support.
This way, you can use as many AD DS features as possible.
For example, if you are sure that you will never add domain controllers that run Windows Server 2003 to the
domain or forest, select the Windows Server 2008 functional level during the deployment process.
However, if you might retain or add domain controllers that run Windows Server 2003, select the Windows
Server 2003 functional level.
When you deploy a new forest, you are prompted to set the forest functional level and then set the domain
functional level.
You cannot set the domain functional level to a value that is lower than the forest functional level.
