Refer to the exhibit. A packet with a source IP address of 192.168.2.4 and a destination IP address of 10.1.1.4 arrives at the HokesB router. What action does the router take?
A.
forwards the received packet out the Serial0/0 interface
B.
forwards a packet containing an EIGRP advertisement out the Serial0/1 interface
C.
forwards a packet containing an ICMP message out the FastEthernet0/0 interface
D.
forwards a packet containing an ARP request out the FastEthernet0/1 interface
but why?!?!?!?!

Technically:
It will forward EIGRP queries if it doesn’t find a feasible successor route. This isn’t part of the choice list.
If it can’t find a route then it will send back a ‘unreachable host’ message back to the source. Hence answer is ‘C’.

The router will discard the packet and send back the ICMP unreachable message back to the sender. The source 192.168.2.4 happens to be on the routing table. (Under subnet 192.168.2.0, via Fa0/0, learn by EIGRP) Therefore the message will be sent back to the source via Fa0/0
