  • Question
  • Which of the following access lists will allow only HTTP traffic into network 196.15.7.0?


  • Options
  • A. access-list 100 permit tcp any 196.15.7.0 0.0.0.255 eq www
  • B. access-list 10 deny tcp any 196.15.7.0 eq www
  • C. access-list 100 permit 196.15.7.0 0.0.0.255 eq www
  • D. access-list 110 permit ip any 196.15.7.0 0.0.0.255
  • E. access-list 110 permit www 196.15.7.0 0.0.0.255

  • Correct Answer
  • access-list 100 permit tcp any 196.15.7.0 0.0.0.255 eq www 

    Explanation
    The first thing to check in a question like this is the access-list number. Right away, you can see that the second option is wrong because it is using a standard IP access-list number. The second thing to check is the protocol. If you are filtering by upper-layer protocol, then you must be using either UDP or TCP; this eliminates the fourth option. The third and last answers have the wrong syntax.
