R1# sh ip int br Interface IP-Address OK? Method Status Protocol FastEthernet0/0 YES manual up up Serial0/0 YES manual up down Serial0/1 unassigned YES NVRAM administratively down down

Hosts with ip address are unable to reach hosts in network Based on the output from R1, what are two possible reasons for the failure?

A. The cable that is connected to serial0/0 on R1 is broken.
B. Interface S0/0 on R2 is administratively down.
C. Interface S0/0 on R1 is configured with an incorrect subnet mask.
D. The IP address that is configured on S0/0 of R2 is not in the correct subnet.
E. Interface S0/0 on R1 is not receiving a clock signal from the CSU/DSU.
F. The encapsulation that is configured on S0/0 of R2 does not match the encapsulation that is configured on S0/0 of R1.

Serial0/0 physical status (OSI Level 1) is UP. The broken cable is physical problem.
Serial0/0 data status (OSI Level 2) is DOWN
so is L2 is down and more upper levels like ip address/subnet mask not problem now.
