Refer to the exhibit.

A technician pastes the configurations in the exhibit into the two new routers shown.
Otherwise, the routers are configured with their default configurations.
A ping from Host1 to Host 2 fails, but the technician is able to ping the S0/0 interface of R2
from Host 1. The configurations of the hosts have been verified as correct. What could be the
cause of the problem?

A.
The serial cable on R1 needs to be replaced.

B.
The interfaces on R2 are not configured properly

C.
R1 has no route to the 192.168.1.128 network.

D.
The IP addressing scheme has overlapping subnetworks.

E.
The ip subnet-zero command must be configured on both routers.

Explanation:
Without a static route pointing to host 2 network the router is unaware of the path to take to
reach that network and reply traffic cannot be sent.
