Two routers are having a connection problem on their serial link. Which two of the following items are likely to result in both sides showing a status of: Serial0/0 is up, line protocol is down ? (Choose two)
The serial cable may have come unplugged on one of the devices
both routers are administratively shutdown
clock rate has not been set on the DCE side
an encapsulation mismatch
clock rate has been set to a 9600
one of the ip addresses is either wrong or has the wrong subnet mask
The output as shown in the graphic means that the IOS command "show interface s0/0/0" is used. As you can see, each router's interface is configured with different encapsulation type, thus, line protocol is "down" due to encapsulation mismatch.
