Refer to the exhibit:
A technician is testing connection problems in the internetwork. What is the problem indicated by the output from HostA?
A.
The routing on Router2 is not functioning properly.
B.
An access list is applied to an interface of Router3.
C.
The Fa0/24 interface of Switch1 is down.
D.
The gateway address of HostA is incorrect or not configured.
Correct answer is A because the TTL of the ICMP message remains 255. That means that R2 router is not receiving the ICMP message.

Look who he pinged…. Why would R2 respond to a ping for R1?
0
0
the answer is d. the ping reply is send by the f0/0 interface of r1 which should be the gateway of host 1. but the host1 doesnt have gateway configured. confused why it is still ping’s even without gateway confiured? it is because they are in thesame subnet. try to do this in packet tracer. we know that the first output of a trace route is the gateway. the error says destination unreachable. i hope its clear.
