Hotspot Question
Your network contains a two-domain on-premises Active Directory Domain Services (AD DS) forest named contoso.com. The forest contains the domain controllers shown in the following table.

All domain controllers are backed up by using Azure Backup.
You create an Active Directory site named Site3. Site1, Site2, and Site3 each has a dedicated site link to the Hub site.
In Site3, you install a new server named Server1.
You need to promote Server1 to an RODC in child.contoso.com by using the Install from Media (IFM) option. The solution must minimize network traffic.
What should you do? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation:
Box 1: DC2
You create IFM by using Windows Azure Backup on DC2.
Box 1: Ntdsutil.exe
Windows Server 2008 and Windows Server 2008 R2 include an improved version of the Ntdsutil tool that you can use to create installation media for an additional domain controller. You can use Ntdsutil.exe to create installation media for additional domain controllers that you are creating in a domain. The IFM method uses the data in the installation media to install AD DS, which eliminates the need to replicate every object from a partner domain controller.
