  • 第6题:

    阅读以下说明,回答问题1至问题4,将解答填入答题纸对应的解答栏内。   【说明】   某公司的IDC(互联网数据中心)服务器Server1采用Windows Server 2003操作系统,IP地址为172.16.145.128/24,为客户提供Web服务和DNS服务;配置了三个网站,域名分别为www.company1.com、www.company2.com和www.company3.com,其中company1使用默认端口。基于安全的考虑,不允许用户上传文件和浏览目录。company2和company3对应的网站目录分别为company1-web、company2-web和company3-web,如图3-1所示。



    【问题1】(2分,每空1分)
    为安装Web服务和DNS服务,Server1必须安装的组件有(1)、(2)。  (1)~(2)备选答案:  A.网络服务 B.应用程序服务器 C.索引服务 D.证书服务 E.远程终端【问题2】(4分,每空2分)
    在IIS中创建这三个网站时,在图3-2中勾选读取(3)和执行,并在图3-3所示的文档选项卡中添加(4)为默认文档。




    【问题3】(6分,每空1分)1.为了节省成本,公司决定在一台计算机上为多类用户提供服务。使用不同端口号来区分不同网站,company1使用默认端口(5),company2和company3的端口应在1025至(6)范围内任意选择,在访问company2或者company3时需在域名后添加对应端口号,使用(7)符号连接。设置完成后,管理员对网站进行了测试,测试结果如图3-4所示,原因是(8)。



    (8)备选答案:
      A.IP地址对应错误  B.未指明company1的端口号  C.未指明company2的端口号  D.主机头设置错误  2.为便于用户访问,管理员决定采用不同主机头值的方法为用户提供服务,需在DNS服务中正向查找区域为三个网站域名分别添加(9)记录。网站company2的主机头值应设置为(10)。【问题4】(8分,每空2分)
    随着company1网站访问量的不断增加,公司为company1设立了多台服务器。下面是ping网站www.company1.com后返回的IP地址及响应状况,如图3-5所示。 从图3-5可以看出,域名www.company1。com对应了多个IP地址,说明在图3-6所示的DNS属性中启用了(11)功能。



    在图3-6中勾选了“启用网络掩码排序”后,当存在多个匹配记录时,系统会自动检检查这些记录与客户端IP的网络掩码匹配度,按照(12)原则来应答客户端的解析请求。如果勾选了“禁用递归”,这时DNS服务器仅采用(13)查询模式。当同时启用了网络掩码排序和循环功能时,(14)优先级较高。
      (14)备选答案:  A.循环 B.网络掩码排序



    答案:
    解析:
    【问题1】(2分,每空1分)(1)B (2)A 这两个答案 可互换位置
    【问题2】(4分,每空2分)(3)运行脚本(如 ASP)(S)
    (4)index.html 【问题3】(6分,每空1分)(5)80 (6)49151 (7): (8)C (9)主机记录或者A
    (10)www.company2.com
    【问题4】(8分,每空2分)启用循环
