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

Which statement about datagram life is true?
Each router increments the TTL value of the datagram until the maximum hop count of the routing protocol is reached. The packet is then returned to the source.

Each router decreases the TTL value by one until it reaches zero. The datagram is then discarded and a time exceeded for message is sent to the source.
The destination device discards the datagram if the TTL value is zero on arrival. An ICMP destination unreachable message is sent back to the source.
