What should you do?

You work as the network administrator at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers on the Domain.com network run Windows Server 2008. Half the client computers run Windows XP Professional, and the rest run Windows Vista.
A number of domain controllers in the Domain.com network are configured to host the forest wide operations master roles. A new company directive states that all domain controllers hosting this master role be decommissioned. You thus decide to have the forest wide operations master roles transferred to a new domain controller named CERTKILLER-DC03 prior to taking down the domain controllers.
What should you do? (Choose all that apply.)

A.
You should consider transferring the Forest-wide server master roles.

B.
You should consider transferring the PDC Master.

C.
You should consider transferring the Schema master.

D.
You should consider transferring the Domain naming master.

E.
You should consider transferring the Secondary domain master.

Explanation:
In order to transfer all forest-wide operation master roles to another domain you need to transfer Domain naming master as well as the Schema master. Schema Master: The schema master domain controller controls all updates and modifications to the schema. To update the schema of a forest, you must have access to the schema master. There can be only one schema master in
the whole forest. Domain naming master: The domain naming master domain controller controls the addition or removal of domains in the forest. There can be only one domain naming master in the whole forest.
