Extended IP access list 110

10 deny tcp 172.16.0.0 0.0.255.255 any eq telnet

20 deny tcp 172.16.0.0 0.0.255.255 any eq smtp

30 deny tcp 172.16.0.0 0.0.255.255 any eq http

40 permit tcp 172.16.0.0 0.0.255.255 any

--------------------------------------------------------------

Notice that in this access list, the network 172.16.0.0 0.0.255.255 is specified as the source but the question asks about "HTTP traffic coming from the internet that is destined for 172.16.12.10″, which means 172.16.0.0 0.0.255.255 is the destination network. So in this case there is no match in our access list and the traffic will be dropped because of the implicit deny all at the end of the ACL. It is surely a tricky question!
