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.
2. 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.
4. 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.
5. The corporate office sends you a new router to connect, but upon connecting the console cable, you see that there is already a configuration on the router. What should be done before a new configuration is entered in the router?
Options
A. RAM should be erased and the router restarted.
B. Flash should be erased and the router restarted.
C. NVRAM should be erased and the router restarted.
D. The new configuration should be entered and saved.
Correct Answer: NVRAM should be erased and the router restarted.
Explanation:
Before you start to configure the router, you should erase the NVRAM with the
erase startup-config command and then reload the router using the
reload command.
6. Which command will copy the IOS to a backup host on your network?
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.
9. 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.
10. 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.
