Explanation:
A Windows Server 2012 Server running the PDC emulator is required.
The requirements for virtualized DC cloninginclude:
The PDC emulator must run Windows Server 2012. You can clone PDC emulator if it is virtualized.

The virtualized DC that is used as a source for cloning must run Windows Server 2012 and be a

member of the Cloneable Domain Controllers group.
Note: Using virtualized domain controller cloning in Windows Server 2012 to expedite forest recovery Virtualized domain controller (DC) cloning simplifies and expedites the process for installing additional virtualized DCs in a domain, especially in centralized locations such as datacenters where several DCs run on hypervisors. After you restore one virtual DC in each domain from backup, additional DCs in each domain can be rapidly brought online by using the virtualized DC cloning process. You can prepare the first virtualized DC that you recover, shut it down, and then copy that virtual hard disk as many times as is necessary in order to create cloned virtualized DCs to build out the domain.
