问题 在Cisco路由器上建立一个名为zwl00的DHCP地址池,地址池的IP地址是176.1 15.100.0/24,其中不用于动态分配的地址有176.1 15.100.2.176.115.100.10,缺省网关为176.1 15.100.1,域名为tj.edu.cn,域名服务器地址为176.1 15.129.26,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

选项 A、Router(config)#ip dhcp pooI zw 100
Router(dhcp-config)#ip dhcp excluded.address 176.115.1 00.2 1 76.115,1 00.1 0
Router(dhcp-config)#network 176.115.100.0 255.255.255.0
Router((dhcp-config)#default-router 176.115.100.1
Router(dhcp-config)#domain-name tj.edu.ca
Router(dhcp-config)#dns-server address 176.115.129.26
Router(dhcp-config)#1ease 0 6 30
B、Router(config)#ip dllcp excluded-address 176.115.100.2 176.115.100.10
Router(config)#ip dhcp pool zw 100
Router(dIlcp-config)#network 176.115.100.0 255.255.255.0
Router(dhcp-config)#default-router 176.1l 5.1 00.1
Router(dhcp-config)#domain-name tj.edu.cn
Router((dhcp-config)#dns.server address l 76.1 1 5.129.26
Router(dhcp-config)#lease 0 6 30
C、Router(config)#ip dhcp excluded.address 176.115.100.2-10
Router(config)#ip dhcp pool zwl 00
Router(dhcp-config)#etwork 176.115.100.0 255.255.255.0
Router(dhcp-config)#default-router 176.1 15.100.1
Router(dhcp-config)#omain-name tj.edu.ca
Router(dhcp-config)#dns-server address 176.115.1 29.26
Router(d11cp-config)#1ease 0 6 30
D、Router(config)#ip dhcp excluded.address 176.1 15.100.2 176.1 15.100.10
Router(config)#ipdhcppoolzw 1 00
Router(dhcp-config)#network 176.115.100.0 255.255.255.0
Router(dhcp-config)#default-router 176.115.1 00.1
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

答案B

解析 Cisco路由器上DHCP地址池的配置:
    步骤1:首先排除不用于动态分配的地址Router(config)#ipdhcpexcluded-addressl76.1 15.100.2176.1 15.100.10;
    步骤2:配置DHCP地址池的名字为zw100。Router(config)#ipdhcppoolzwl00;
    步骤3:配置IP地址池的子网地址和子网掩码:Router(dhcp-config)#networkl76.115.100.0255.255.255.0:
    步骤4:配置缺省网关:Router(dhcp-config)#default-router 176.115.100.1;
    步骤5:配置IP地址池的域名:Router(dhcp.config)#domain-name tj.edu.cn;
    步骤6:配置域名服务器的IP地址:Router(dhcp-config)#dns-server address l 76.1l 5.129.26;
    步骤7:配置租借时间为6小时30分钟。Router(dhcp.config)#1ease 0 6 30。
    格式为:lease天数小时数分钟数,因此选项B正确。
