    在Linux 系统中配置DHCP服务器,该服务器配置文件的部分内容如下:

    subnet 192.168.1.0 netmask 255.255.255.0 {

    option routers 192.168.1.254;

    option subnet-mask 255.255.255.0;

    option broadcast-address 192.168.1.255;

    range 192.168.1.100 192.168.1.200;

    default-lease-time 21600;

    max-lease-time 43200;

    host webserver {

    hardware ethernet 52:54:AB:34:5B:09;

    fixed-address 192.168.1.100;

    }

    }

    在主机webserver 上运行ifconfig命令时显示如下,根据DHCP配置,填写空格中缺少的内容。

    该网段的网关IP地址为 (7) ,域名服务器 IP地址为 (8) 。

    [Huawei-ip-pool-x]next-server 192.168.2.2

    答案:A
    解析:
    此题主要考查对华为交换机的基础配置命令,显然错误提示为输入的网络没有在指定的地址池内。可以看到四个选项中,必须要求网关与地址池的地址在同一个子网,否则就会报错。因此答案是A。
