Since the question never mentioned anything about a suspended session, you can assume that the Telnet session is still open, and you would just type
exit to close the session.
3. Which three commands can be used to check LAN connectivity problems on a router?
The best answers, the ones you need to remember, are that either an access control list is filtering the Telnet session or the VTY password is not set on the remote device.
5. You need to gather the IP address of a remote switch that is located in Hawaii. What can you do to find the address?
Options
A. Issue the show ip arp command on the router connected to the switch.
B. Issue the show ip route command on the router connected to the switch.
C. Issue the show cdp neighbor command on the router connected to the switch.
D. Issue the show cdp neighbors detail command on the router connected to the switch.
Correct Answer: Issue the show cdp neighbors detail command on the router connected to the switch.
Explanation:
Although option A is certainly the "best" answer, unfortunately option D will work just fine and your boss would probably prefer you to use the
show cdp neighbors detail command.
6. Which command displays the configuration register setting?
Correct Answer: Tells the router to look in NVRAM for the boot sequence
Explanation:
The default configuration setting of 0x2102 tells the router to look in NVRAM for the boot sequence.
8. What should the configuration register value be after you successfully complete the password recovery procedure and return the router to normal operation?
All Cisco routers have a default configuration register setting of
0x2102, which tells the router to load the IOS from flash memory and the configuration from NVRAM.
9. You save the configuration on a router with the copy running-config startup-config command and reboot the router. The router, however, comes up with a blank configuration. What can the problem be?
Options
A. You didn't boot the router with the correct command.
B. NVRAM is corrupted.
C. The configuration register setting is incorrect.
D. The newly upgraded IOS is not compatible with the hardware of the router.
Correct Answer: The configuration register setting is incorrect.
Explanation:
If you save a configuration and reload the router and it comes up either in setup mode or as a blank configuration, chances are you have the configuration register setting incorrect.
10. What information is displayed by the show hosts command?
Temporary DNS entries
The names of the routers created using the hostname command
