Routers R1 and R2 are on the same network segment, and both routers use interface
Ethernet0/0. If R1 loses communication to R2, which two terns should you check as you begn
GigabitEthernetO/0. If R1 lose: troubleshooting? (Choose two )
A. Verify that R2 is using 802 1q encapsulation
B. Verify that the GigabrtEthernet0/0 interfaces on R1 and R2 are configured with the same subnet mask.
C. Verify that the R1 GigabitEthernet0/0 interface is up and the line protocol is down.
D. Verify that R1 and R2 both are using HDLC encapsulation
E. that the R1 GigabitEthernet0/0 interface is up and the line protocol is up.
