What should you do?

You are working as an enterprise administrator at Domain.com. The Domain.com network consists of a single Active Directory forest. The servers on the Domain.com network runs Windows Server 2008 and Windows server 2003.
Domain.com has its headquarters in Chicago and a branch office in Dallas. Domain.com contains a server that has Active Directory Domain Services (AD DS) installed. The Dallas office does not have an administrator or IT personnel. You have received instruction from the CIO to setup a Read-Only Domain Controller (RODC) on the Server Core installation computer in Dallas.
What should you do?

A.
You need to run an unattended installation of AD DS.

B.
You need to run an attended installation of AD DS.

C.
You need to run RODC through AD DS.

D.
You need to run AD DS by using the image of AD DS.

Explanation:
You need to run an unattended installation of AD DS to setup RODC at the branch office. Domain Controllers can be installed very easily by using RODC. You can also install RODC on a Server Core installation of Windows Server 2008. However, you need to be a member of the Domain Admins group or authority to perform installation in order to install RODC. You should not perform an attended installation of AD DS because you won’t be able to install RODC on a Server Core installation. Only unattended installations of AD D S can be performed to install RODC.
