参考答案和解析
正确答案：D
解析：Explanation:
The split horizon rule states:
* Never advertise a route out of the interface through which you learned it.

For instance, in Figure 4a below, if Router One is connected to Routers Two and Three through a single multipoint interface (such as Frame. Relay), and Router One learned about Network A from Router Two, it will not advertise the route to Network A back out the same interface to Router Three. Router one assumes that Router Three would learn about Network A directly from Router Two.


Incorrect Answers:
A: There is no such requirement

B: Distance vector protocols updates routing table at regular intervals instead of Topology changes

C: This is the definition of the poison reverse rule, not the split horizon rule.

  • 第2题：

    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.

    E. Use the Active Directory Domains and Trusts tool to change the Ezonexam.local domain mode to native mode.

    F. Use the Active Directory Domains and Trusts to change the marketing.Ezonexam.local domain mode to native mode.


    正确答案：BCF
    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.

    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.

    (A) which (C) that

    选B


    这句话貌似定语从句。而实际上，前面的部分就是状语，后半句与countries没有修饰关系（因为1.后半句缺主语，但空格的位置用countries不能替换，否则语义不对。2.后半句不缺宾语。）所以后半句的（)is called equality作主语.是主语从句。
    在选项中，只有what引导主语从句。

    It's said that he's looking for a new job, one_________ he can get more free time.

    A．when
    B．where
    C．that
    D．which

    答案：B
    解析：
    考查定语从句。one是a newjob的同位语，同时one是先行词，后面是个定语从句，由于定语从句he can get more free time不缺少任何成分，说明空格处在从句中作状语，需要用where引导，意为“从新工作中获得更多的自由时间”。如果选which的话，应该是one(a job)from which he can get more free time，故选B。
