问题 What three pieces of information can be used in an extended access list to filter traffic?

选项 A、protocol
B、VLAN number
C、TCP or UDP port numbers
D、source switch port number
E、source IP address and destination IP address

答案A,C,E

解析 ACL是基于三层的过滤,因此他可以基于ip,port number来过滤流量,扩展的访问控制列表是可以基于源和目的的同时的过滤。
