You are the network administrator for Ezonexam.
Ezonexam14 is one of 10 Windows NT Server 4.0 member servers in a Windows 2000 domain named marketing.Ezonexam.local. The marketing domain also has five Windows NT 4.0 backup domain controllers. The marketing.Ezonexam.local domain is the child domain of Ezonexam's root domain, Ezonexam.local.
You want to upgrade Ezonexam14 to Windows 2000 Server and change the role of Ezonexam14 from a member server to a domain controller in the same domain. You also want to be able to implement Universal Groups in the marketing domain.
What should you do? (Each correct answer presents part of the solution. Choose three)
A. Upgrade all of the Windows NT Server 4.0 member servers in the marketing domain to Windows 2000 Server.
B. Upgrade all of the Windows Server 4.0 backup domain controllers in the marketing domain to Windows 2000 Server.
C. Upgrade Ezonexam14 to Windows 2000 Server. Run the dcpromo command to make Ezonexam14 a domain controller in the marketing.Ezonexam.local domain.
D. Upgrade Ezonexam14 to Windows 2000 Server. Run the dcpromo command to make Ezonexam14 to a domain controller in the Ezonexam.local domain.

B,C,F 解析：Explanation: A backup domain controller (BDC) - In a Windows NT Server domain, a computer that receives a copy of the domain's security policy and domain database and authenticates network logons. It provides a backup if the primary domain controller (PDC) becomes unavailable.
Once a server has been installed with Windows Server 2000, you can upgrade it to a domain controller through the Dcpromo utility.
Native-mode domains have additional features that are unavailable to mixed-mode domains, but no longer support NT 4 domain controllers. In order to support universal groups, the domain must be configured for Windows 2000/2003 native mode. If the domain is configured for Windows 2000/2003 mixed mode (which supports Windows NT 4.0), then universal groups are not supported.
Incorrect answers:
A: You should be upgrading the domain controllers and not the member servers.
D: This option is faulty since it asks for the upgrading of the domain controllers in Ezonexam.local instead of marketing.Ezonexam.local.
E: This option is faulty as it should be changing the marketing.Ezonexam.local domain and not the Ezonexam.local domain.
