29 A network administrator trying to deny Telnet traffic from the<br>
192.5.5.0 network to the 201.100.11.0 network entered the commands<br>
shown in the graphic. When monitoring the network, the administrator<br>
noticed that the Telnet packets are still passing between those<br>
networks. What is the cause?<br>
The router ignored this type of traffic because it required a standard access
list to be configured instead<br>
of an extended one.<br>
The wrong port was configured for the ACL so Telnet traffic was still
allowed.<br>
The access list has not been assigned to an interface.<br>
The permit ip any any allowed all traffic to pass regardless of the other
statements listed in this ACL.<br>
