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 Host2 fails, but
the technician is able to ping the S0/0 interface of R2 from Host1. The configurations of the hosts
have been verified as correct. What is 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:
Whenever a node needs to send data to another node on a network, it must first
know where to send it. If the node cannot directly connect to the destination node, it has to send it
via other nodes along a proper route to the destination node. A remote network is a network that
can only be reached by sending the packet to another router. Remote networks are added to the
routing table using either a dynamic routing protocol or by configuring static routes. Static routes
are routes to networks that a network administrator manually configured.So R should have static
route for the 192.168.1.128.
