在Cisco路由器上建立一个名为zw246的DHCP地址池 地址池的IP地址是176.115.246.0／24 其中不用于动

在Cisco路由器上建立一个名为zw246的DHCP地址池，地址池的IP地址是176.115.246.0/24，其中不用于动态分配的地址有176.115.246.2～176.115.246.10，缺省网关为176.115.246.1，域名为tj.edu.cn，域名服务器地址为176.115.129.26，地址租用时间设定为6小时30分钟。下列DHCP地址池的配置，正确的是

A）Router (config)#ip dhcp pool zw246

Router (dhcp-config)#ip dhcp excluded-address 176.115.246.2 176.115.246.10

Router (dhcp-config)#network 176.115.246.0 255.255.255.0

Router (dhcp-config)#default-router 176.115.246.1

Router (dhcp-config)#domain-name tj.edu.cn

Router (dhcp-config)#dns-server address 176.115.129.26

Router (dhcp-config)#lease 0 6 30

B）Router (config)#ip dhcp excluded-address 176.115.246.2-10

Router (config)#ip dhcp pool zw246

Router (dhcp-config)#network 176.115.246.0 255.255.255.0

Router (dhcp-config)#default-router 176.115.246.1

Router (dhcp-config)#domain-name tj.edu.cn

Router (dhcp-config)#dns-server address 176.115.129.26

Router (dhcp-config)#lease 0 6 30

C）Router (config)#ip dhcp excluded-address 176.115.246.2 176.115.246.10

Router (config)#ip dhcp pool zw246

Router (dhcp-config)#network 176.115.246.0 255.255.255.0

Router (dhcp-config)#default-router 176.115.246.1

Router (dhcp-config)#domain-name tj.edu.cn

Router (dhcp-config)#dns-server address 176.115.129.26

Router (dhcp-config)#lease 0 6 30

D）Router (config)#ip dhcp excluded-address 176.115.246.2 176.115.246.10

Router (config)#ip dhcp pool zw246

Router (dhcp-config)#network 176.115.246.0 255.255.255.0

Router (dhcp-config)#default-router 176.115.246.1

Router (dhcp-config)#domain-name tj.edu.cn

Router (dhcp-config)#dns-server address 176.115.129.26

Router (dhcp-config)#lease 30 6 0
