    You are the network administrator for Ezonexam.

    ServerEzonexam14 is a Windows NT Server 4.0 computer. ServerEzonexam14 is also a member server in a Windows 2000 domain named marketing.Ezonexam.local. The marketing.Ezonexam.local domain also has five Windows NT Server 4.0 backup domain controllers.

    You want to upgrade ServerEzonexam14 to a Windows 2000 member server in the marketing.Ezonexam.local domain. You also want to be able to implement Universal Groups in the marketing.Ezonexam.local domain.

    What should you do? (Each correct answer presents part of the solution. Choose three)

    A. Reinstall Windows NT Server 4.0 on ServerEzonexam14 in the same WINNT folder, and make ServerEzonexam14 a BDC in the marketing domain.

    B. Run the Active Directory Installation Wizard to make ServerEzonexam14 a domain controller in the marketing.Ezonexam.local domain.

    C. Run the Active Directory Installation Wizard to convert ServerEzonexam14 to a domain controller in the fabrikam.local domain.

    D. Upgrade all the Windows NT Server 4.0 backup domain controllers in marketing.Ezonexam.local to Windows 2000 Server.

    E. Upgrade all the Windows NT Server 4.0 backup domain controllers in Ezonexam.local to Windows 2000 Server.

    F. Upgrade ServerEzonexam14 to Windows 2000 Server.

    G. Upgrade the marketing.Ezonexam.local domain to native mode.


    正确答案：DFG
    D,F,G 解析：Explanation: A member server is a Windows Server 200 server that has been installed as a non-domain controller and joined to a domain. This allows the server to operate as a file, print, and application server without the overhead of account administration. A domain controller is a Windows Server 2000 computer that is configured to store the domain database, commonly referred to as Active Directory. 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. Thus to comply with the requirements of having universal groups and upgrading ServerEzonexam14 to a Windows 2000 member server in the marketing.Ezonexam.local domain, options D, F and G is the solution.

    Incorrect answers:
    A: 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. A domain is not required to have a BDC. This is not what is required.

    B: Making ServerEzonexam14 a domain controller is not the same as upgrading it to a Windows 2000 member server. A member server must be upgraded to a domain controller.

    C: You should be upgrading ServerEzonexam14 to a Windows 2000 Member server in the marketing.Ezonexam.local domain and not the fabrikam.local domain.

    E: This option is faulty since it asks for the upgrading of the domain controllers in Ezonexam.local instead of marketing.Ezonexam.local.
