使用名字标识访问控制列表的配置方法，在Cisc0路由器的gO／3接口封禁端口号为1434的UDP数据包和端口号为4444的TCP数据包，正确的访问控制列表的配置是()。
A.Router(eonfig)#ip access-list extended WINSQLRouter(config-ext-nacl)#deny any any udp eq 1434Router(config-ext-nacl)#deny any any tcp eq 4444Router(config-ext-nacl)#permit ip any anyRouter(config-ext-nacl)#exitRouter(config)#interface gO／3Router(eonfig-if)#ip access-group WINSQL inRouter(config-if)#ip access-group WINSQL out
B.Router(config)#ip access-list standard WINSQLRooter(config-std-nael)#deny udp any any eq 1434Router(config-std-nacl)#deny tcp any any eq4444Router(config-std-nacl)#permit ip any anyRouter(corffig-std-nacl)#exitRouter(config)#interface gO／3Router(config-if)#ip access-group WINSQL inRooter(config-if)#ip access-group WINSQL out
