在网络部署完成后进行如下测试:

1.在主机host101上对Router2的F0/0口及网络1的host1进行了连通性测试,结果如图1-2和图1-3所示。

host101>ping 192.168.0.1

Pinging 192.168.0.1 with 32 bytes of data:

3.查看路由器Router3的路由表,结果如图1-5所示。

Router3>show ip route

R 192.168.0.0/24 [120/1] via 202.117.112.1, 00:00:24,Serial2/0

【问题1】(6分)

请填写hostl的Internet协议属性参数。

IP地址: (1)

子网掩码: (2)

默认网关: (3)


正确答案:

1-2和图1-3连通性测试很快得知Router2F0/0接口和host1IP地址分别是192.168.0.1192.168.0.2。图1-5Router3路由表中学习到192.168.0.0/24的路由,可见对于host1而言,其网卡参数为中,IP地址为192.168.0.2,子网掩码为255.255.255.0,其网关为Router2F0/0接口地址即192.168.0.1

【问题1】(6分,每空2分)

(1)192.168.0.2

(2)255.255.255.0

(3)192.168.0.1

第5题:

如果在-台主机的Windows环境下执行Ping命令得到下列信息:Pinging www.nankai.edu.cn[202.113.16.33 ]with 32 bytes of data:Reply from 202.113.16.33:bytes=32 time<;1ms TTL=128Reply from 202.113.16.33:bytes=32 time<;1ms TTL=128Reply from 202.113.16.33:bytes=32 time<;1ms TTL=128Reply from 202.113.16.33:bytes=32 time<;1ms TTL=128Ping statistics for 202.1 13.16.33:Packets:Sent=4,Received=4,Lost=0(0%loss),Approximate round trip times in milli-seconds:Minimum=0ms,Maximum=Oms,Average=Oms那么下列结论中无法确定的是( )。

B.本机使用的DNS服务器工作正常

C.主机www.nankai.edu.cn上WWW服务工作正常

D.主机www.nankai.edu.cn的网关配置正确


正确答案:C
通过www.nankai.edu.cn这个域名,可以正确转换到IP202.113.16.33,说明为www.nankai.edu.cn提供名字解析的服务器以及本机使用的DNS服务器工作正常,并且主机www.nankai.edu.cn,但并不能说明该主机www服务工作正常。因此C选项错误。
