CCNA 640-607 Practice Exam Two
At the console terminal, you type
Router#show interface serial 1
You receive the following as part of the output:
Serial1 is up, line protocol is down
What could cause this? Choose four.
A. There are no keepalives
B. There is no clock rate
C. There is a wrong connector
D. In a back-to-back connection, the other end of the connection is
administratively down
E. The cable is disconnected
Answer: A, B, C, and D
If the cable were physically disconnected, then it would show Serial1 is down, line protocol is down. When Serial1 is up, line protocol is down, it points to a layer 2 problem which could be no keepalives, no clock rate, wrong connector, or in a back-to-back connection, the other end of the connection is administratively down. If Serial1 is administratively down (line protocol is down) then the administrator manually disabled the interface.
Router interfaces are generally configured by the command:
Router(config)#interface type number
Which routers need more information for configuration?

At the console terminal, you type
Router#show interface serial 1
You receive the following as part of the output:
Serial1 is administratively down, line protocol is down
What could cause this?
A. There are no keepalives
B. There are keepalives
C. There is no clock rate
D. The interface has been manually disabled
Answer: D
If the cable were physically disconnected, then it would show Serial1 is down, line protocol is down. When Serial1 is up, line protocol is down, it points to a layer 2 problem which could be no keepalives, no clock rate, wrong connector, in a back-to-back connection, the other end of the connection is administratively down. If Serial1 is administratively down, line protocol is down, then the administrator manually disabled the interface.
