  • Question
  • You configure the following access list:

    access-list 110 deny tcp 10.1.1.128 0.0.0.63 any eq smtp
    access-list 110 deny tcp any eq 23
    int ethernet 0
    ip access-group 110 out
    What will the result of this access list be?


  • Options
  • A. Email and Telnet will be allowed out E0.
  • B. Email and Telnet will be allowed in E0.
  • C. Everything but email and Telnet will be allowed out E0.
  • D. No IP traffic will be allowed out E0.

  • Correct Answer
  • No IP traffic will be allowed out E0. 

    Explanation
    If you add an access list to an interface and you do not have at least one permit statement, then you will effectively shut down the interface because of the implicit deny any at the end of every list.
