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 AcmeB 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 FastEthemet0/0 interface
D.
forwards a packet containing an ARP request out the FastEthemet0/1 interface
Explanation:
CCNA – EIGRP Common Question http://www.orbitco-ccna-pastquestions.com/CCNA—EIGRPCommon-Question.php
Looking at the output above, there is no IP route for 10.1.1.4 address on AcmeB routing table. If the
router can no find a specific path in its routing table to a particular route,( In this case no path is
found so AcmeB) the router will inform the source host with an ICMP message that the destination is
unreachable and this will be through the same interface it has received the packet (interface Fa0/0
network 192.168.3.0/28 from the exhibit).
I think the reason it goes out the fa0/0 interface is because the 192.168.2.8 network is actually the 192.168.2.0/24. Since the subnet mask was NOT included on the routing table line entry for 192.168.2.8, cant it be assumed to be a class C which would then be in the same subnet as 192.168.2.4?
I think that cements my doubts about this question, I definitely choose C.
