Which FSMO role should you transfer to DC2?

Your network contains an Active Directory domain named contoso.com. The domain contains six domain controllers.

The domain controllers are configured as shown in the following table.

The network contains a server named Server1 that has the Hyper-v server role installed. DC6 is a virtual machine that is hosted on Server1. You need to ensure that you can clone DC6.

Which FSMO role should you transfer to DC2?
A . Rid master
B . Domain naming master
C . PDC emulator
D . Infrastructure master

Answer: C

Explanation:

The clone domain controller uses the security context of the source domain controller (the domain controller whose copy it represents) to contact the Windows Server 2012 R2 Primary Domain Controller (PDC) emulator operations master role holder (also known as flexible single master operations, or FSMO). The PDC emulator must be running Windows Server 2012 R2, but it does not have to be running on a hypervisor.
