- B. If no router activity has been detected in 1 hour and 35 minutes, the console will be locked out.
- C. If no commands have been typed in 1 minute and 35 seconds, the console connection will be closed.
- D. If you're connected to the router by a Telnet connection, input must be detected within 1 minute and 35 seconds or the connection will be closed. Discuss

Options- A. 1, 2 and 4
- B. 2, 3 and 5
- C. 3 and 4 only
- D. None of the above Discuss
- 6. You type Router#sh ru and receive an % ambiguous command error. Why did you receive this message?
Options- A. The command requires additional options or parameters.
- B. There is more than one show command that starts with the letters ru.
- C. There is no show command that starts with ru.
- D. The command is being executed from the wrong router mode. Discuss

Options- A. show running-config
- B. show startup-config

- C. Static route
- D. IGRP route
- E. They will all load-balance. Discuss

- D. Router(config-router)# no routing updates Discuss
- 10. What is route poisoning?
Options- A. It sends back the protocol received from a router as a poison pill, which stops the regular updates.
- B. It is information received from a router that can't be sent back to the originating router.

Correct Answer: show interfaces
Explanation:
With the
show interfaces command, you can view the configurable parameters, get statistics for the interfaces on the router, verify if the interfaces are shut down, and see the IP address of each interface.
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: 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.
Correct Answer: It describes when a router sets the metric for a downed link to infinity.
Explanation:
Another way to avoid problems caused by inconsistent updates and to stop network loops is route poisoning. When a network goes down, the distance-vector routing protocol initiates route poisoning by advertising the network with a metric of 16, or unreachable (sometimes referred to as infinite).
