  • 第3题：

    配置DHCP服务器IP地址池的地址为193.45.98.0/24，其中193.45.98.10～193.45.98.30用做静态地址分配，正确的配置语句是______。

    A．ip dhcp excluded-address 193.45.98.10.193.45.98.30 network 193.45.98.0 255.255.255.0

    C．ip dhcp excluded-address 193.45.98.10 193.45.98.30 network 193.45.98.0 0.0.0.255

    D．ip dhcp excluded-address 193.45.98.10 193.45.98.30 network 193.45.98.0 255.255.255.0


    正确答案：D
    解析：本试题中，地址块“193.45.98.0/24”的“/24”是子网掩码255.255.255.0的简化表达形式。在DHCP Pool配置模式下，使用命令networknetwork-number＞[mask|/prefix-length]配置分配给DHCP客户的有效IP地址池的子网地址和子网掩码。其中，子网掩码参数允许以点分十进制数、掩码前缀长度两种形式表达。因此，DHCP服务器IP地址池的地址为193.45.98.0/24的配置语句，如下所示：
      Router (dhcp-config)# network l93.45.98.0 255.255.255.0
      或：
      Router (dhcp-eonfig)# network 193.45.98.0/24
      在全局配置模式“Router(config)#”下，使用命令ip dhcp excluded-address low-address [high-address]将所要保留的IP地址从预定义的IP地址池中排除，使之成为不能动态分配的IP地址。若将IP地址池中 193.45.98.10～193.45.98.30用做静态地址分配，则相关的配置语句如下：
      Router (confiq)#ip dhcp excluded-address 193.45.98.10 193.45.98.30
      本试题选项A、选项B、选项C的配置语句，分别存在不符合以上两条命令的语法格式。
