Correct Answer: The administrator has the interface shut down.
Explanation:
If an interface is shut down, the
show interface command will show the interface as administratively shut down. (It is possible that no cable is attached, but you can't tell that from this message.)
Correct Answer: erase start
Explanation:
The
erase startup-config command erases the contents of NVRAM and will put you in setup mode if the router is restarted.
Correct Answer: service password-encryption
Explanation:
The command
service password-encryption, from global configuration mode, will encrypt the passwords.
Correct Answer: Setup mode
Explanation:
If you delete the startup-config and reload the router, the router will automatically enter setup mode. You can also type
setup from privileged mode at any time.
Correct Answer: Ctrl+C
Explanation:
You can exit setup mode at any time by using the keystroke
Ctrl+C.
Correct Answer: Physical layer
Explanation:
If you see that a serial interface and the protocol are both down, then you have a Physical layer problem. If you see
serial1 is up,
line protocol is down, then you are not receiving (Data Link) keepalives from the remote end.
Correct Answer: Part of the command is missing.
Explanation:
You can view the interface statistics from user mode, but the command is
show interface serial 0/0.
Correct Answer: show controllers serial 0
Explanation:
The
show controllers serial 0 command will show you whether either a DTE or DCE cable is connected to the interface. If it is a DCE connection, you need to add clocking with the clock rate command.
Correct Answer: 2, 3 and 5
Explanation:
The commands
show protocols,
show interfaces, and
show ip interface will show you the layer 1 and 2 status and the IP addresses of your router's interfaces.
Correct Answer: reload
Explanation:
To completely replace the running-config with the startup-config, you must reload the router. Note : You may have picked option C, which isn't a bad answer. Remember, though, it doesn't replace the configuration, it appends it.
