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.
Install the DNS Server role.

B.
Enable the global catalog server.

C.
Install the Active Directory Certificate Services role.

D.
Transfer the schema master.

Explanation:
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.
