Correct Answer: Router(config)#line vty 0 4
Explanation:
From global configuration mode, use the
line vty 0 4 command to set all five default VTY lines.
Correct Answer: If no commands have been typed in 1 minute and 35 seconds, the console connection will be closed.
Explanation:
The
exec-timeout command is set in minutes and seconds.
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.
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: 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: Router#copy run startup
Explanation:
To copy the running-config to NVRAM so that it will be used if the router is restarted, use the
copy running-config startup-config command (
copy run start for short).
Correct Answer: There is more than one show command that starts with the letters ru.
Explanation:
The
% ambiguous command error means that there is more then one possible command that starts with
ru. Use a question mark to find the correct command.
Correct Answer: show interfaces
Explanation:
The command
show ip protocols will actually show you the broadcast address for each interface - too bad it isn't a possible answer. Your best answer is
show interfaces, which will provide the IP address and mask for each interface.
Correct Answer: Static route
Explanation:
Static routes have an administrative distance of 1 by default. Unless you change this, a static route will always be used over any other found route. IGRP has an administrative distance of 100, and RIP has an administrative distance of 120, by default.
Correct Answer: Router(config-router)# passive-interface s0
Explanation:
The
(config-router)#passive-interface command stops updates from being sent out an interface, but route updates are still received.
