Your network contains an Active Directory forest named contoso.com. The forest contains
three domains named contoso.com, childl.contoso.com, and child2.contoso.com. The
childl.contoso.com domain contains five domain controllers. The domain controllers are
configured as shown in the following table.

You plan to decommission the child1.contoso.com domain.
You need to identify which two FSMO roles can be moved from childl.contoso.com to
child2.contoso.com.
Which two FSMO roles should you identify? (Each correct answer presents part of the
solution. Choose two.)

A.
Domain naming master
B.Schema master
C.Infrastructure master
D.PDC emulator
E.RID master

Explanation:
Forestwide Operations Master Roles
The schema master and domain naming master are forestwide roles, meaning that there is
only one schema master and one domain naming master in the entire forest.
Note:
* Operations Master Roles
The five operations master roles are assigned automatically when the first domain controller
in a given domain is created. Two forest-level roles are assigned to the first domain
controller created in a forest and three domain-level roles are assigned to the first domain
controller created in a domain.
* The five FSMO roles [in Windows 2003] are:
Schema master – Forest-wide and one per forest.
Domain naming master – Forest-wide and one per forest.
RID master – Domain-specific and one for each domain.
PDC – PDC Emulator is domain-specific and one for each domain.
Infrastructure master – Domain-specific and one for each domain.
