Your network contains an Active Directory forest named contoso.com. All domain controllers currently
run Windows Server 2008 R2.
You plan to install a new domain controller named DC4 that runs Windows Server 2012 R2.
The new domain controller will have the following configurations:
 Schema master
 Global catalog server
 DNS Server server role
 Active Directory Certificate Services server role
You need to identify which configurations cannot be fulfilled by using the Active Directory Domain
Services Configuration Wizard.Which two configurations should you identify? (Each correct answer presents part of the solution.
Choose two.)

A.
Enable the global catalog server.

B.
Transfer the schema master.

C.
Install the Active Directory Certificate Services role.

D.
Install the DNS Server role.

Explanation:
AD Installation Wizard will automatically install DNS and allows for the option to set it as a global catalog
server. ADCS and schema must be done separately.
