题目内容：
在一台 Cisco 路由器上执行 show access-list 命令显示如下一组信息 Extended IP access list port4444
permit icmp 202.38.97.0,wildcard bits 0.0.0.255 any
deny icmp any any
deny udp any any eq 1434
deny tcp any any eq 4444
permit ip any any
根据上述信息，正确的 access-list 的配置是 (P197-198) A．Router(config)#ip access-list extended port4444
Router(config-ext-nacl)#deny icmp any any
Router(config-ext-nacl)#deny udp any any eq 1434
Router(config-ext-nacl)#deny tcp any any eq 4444
Router(config-ext-nacl)#permit icmp 202.38.97.0 0.0.0.255 any
Router(config-ext-nacl)#permit ip any any
B．Router(config)#access-list port4444 permit icmp 202.38.97.0 0.0.0.255 any
Router(config)#access-list port4444 deny icmp any any
Router(config)#access-list port4444 deny udp any any eq 1434
Router(config)#access-list port4444 deny tcp any any eq 4444
Router(config)#access-list port4444 permit ip any any
C．Router(config)#ip access-list extended port4444
Router(config-ext-nacl)#permit icmp 202.38.97.0 0.0.0.255 any
Router(config-ext-nacl)#deny any any icmp
Router(config-ext-nacl)#deny udp any any eq 1434
Router(config-ext-nacl)#deny tcp any any eq 4444
Router(config-ext-nacl)#permit ip any any
D．Router(config)#ip access-list extended port4444
Router(config-ext-nacl)#permit icmp 202.38.97.0 0.0.0.255 any
Router(config-ext-nacl)#deny icmp any any
Router(config-ext-nacl)#deny udp any any eq 1434
Router(config-ext-nacl)#deny tcp any any eq 4444
Router(config-ext-nacl)#permit ip any any
