2007年春，ARP木马大范围流行。木马发作时，计算机网络连接正常却无法打网页。由于ARP木马发出大量欺骗数据包，导致网络用户上网不稳定，甚至网络短时瘫痪。 在以太网中，源主机以 (1) 方式向网络发送含有目的主机IP地址的ARP请求包；目的主机或另一个代表该主机的系统，以 (2) 方式返回一个含有目的主机IP地址及其MAC地址对的应答包。源主机将这个地址对缓存起来，以节约不必要的ARP通信开销。ARP协议 (3) 必须在接收到ARP请求后才可以发送应答包。 ARP木马利用感染主机向网络发送大量虚假ARP报文，主机 (4) 导致网络访问不稳定。例如，向被攻击主机发送的虚假ARP报文中，目的IP地址为 (5) ，目的MAC地址为感染木马的主机MAC地址，这样会将同网段内其他主机发往网关的数据引向发送虚假ARP报文的机器，并抓包截取用户口令信息。 备选答案： (1)A) 单播 B) 多播 C) 广播 D) 任意播 (2)A) 单播 B) 多播 C) 广播 D) 任意播 (3)A) 规定 B) 没有规定 (4)A) 只有感染ARP木马时才会 B) 没有感染ARP木马时也有可能 C) 感染ARP木马时一定会 D) 感染ARP木马时一定不会 (5)A) 网关TP地址 B) 感染木马的主机IP地址 C) 网络广播IP地址 D) 被攻击主机II)地址
IIS(Internet Information Server)是微软公司推出的 [16] 服务器程序。安装Windows Server 2003时，将自动安装IIS并建立默认的站点．IIS只能运行在基于 [17] 技术的Windows平台上，因此不能在 Windows98或Windows ME上安装。IIS的安装步骤如下： (1)准备好Windows Server 2003安装光盘，放置于光盘驱动中。 (2)选择“开始”→“设置”→“控制面板”命令，打开“控制面板”窗口，然后再打开“添加/删除程序”对话框。 (3)单击 [18] 按钮，弹出“Windows组件向导”对话框。在这里，可以看到目标系统中已经安装和没有安装的各种Windows组件。目前打勾的选项是已经安装的组件，空白的是没有安装的组件，打勾但是颜色发灰的是部分安装的组件．这里将要安装的是“Internet信息服务(IIS)”。 (4)用鼠标选中 [19] ，然后单击右下角的 [20] 按钮。 (5)确认所有必需的组件前都已打勾后，单击“确定”按钮，返回到“添加/删除Windows组件”窗口，单击“下一步”按钮，这时安装程序开始从Windows安装光盘复制所需的文件到硬盘上。
