【解析】VLANID的数值范围是1~4094,其中2~1000用于以太网,1002~1005预留给FDDI和Token Ring VLANs使用,1025~4094是扩展的VLAN ID,其他为保留ID号,题中只有B选项符合题意。
A.set interface vlan1 203.29.166.90.0.0.255 203.29.166.1 | B.set interface vlan1 203.29.166.9 255.255.255.0 203.29.166.1 | C. set interface sc0 203.29.166.9 0.0.0.255 203.29.166.1 | D.set interface sc0 203.29.166.9 255.255.255.0 203.29.166.1 |
【答案】D
【解析】Catalyst 6500配置IP地址的命令格式为:set interface sc0 <ip_addr>
A.Router(config)#access-list 110 permit icmp 212.78.170.166 0.0.0.0 any Router(config)#access-list 110 deny icmp any any Router(config)#access-list 110 permit ip any any | B.Router(config)#access-list 110 permit icmp 212.78.170.0 255.255.255.224 any Router(config)#access-list 110 permit ip any any Router(config)#access-list 110 deny icmp any any | C. Router(config)#access-list 110 permit iemp 212.78.170.0 0.0.0.255 any Router(config)#access-list 110 permit ip any any | D. Router(config)#access-list 110 permit icmp 212.78.170.160 0.0.0.31 any Router(config)#access-list 110 deny any any Router(config)#access-list 110 permit ip any any |
【答案】D
【解析】212.78.170.166/27的前27位为网络前缀,即前24位不变,第25位为1,26位为0,27位为1,其余为0,经过计算得地址212.78.170.160,后5位置1,其余为0时,通配符掩码为0.0.0.31,故选D。
