Solution(By Examveda Team)
When trying to find the best answer to an access-list question, always check the access-list number and then the protocol. When filtering to an upper-layer protocol, you must use an extended list, numbers 100-199 and 2000-2699. Also, when you filter to an upper-layer protocol, you must use eithertcp
or udp
in the protocol field. If it says ip
in the protocol field, you cannot filter to an upper-layer protocol. SMTP uses TCP. Join The Discussion
