Managing Cisco Internetwork Questions

Correct Ans:show version
The show version command provides you with the current configuration register setting.
3. You telnet to a router and make your necessary changes; now you want to end the Telnet session. What command do you type in?

Before you back up an IOS image to a laptop directly connected to a router's Ethernet port, make sure the TFTP server software is running on your laptop, that the Ethernet cable is a "crossover," and that the laptop is in the same subnet as the router's Ethernet port, and then you can use the copy flash tftp command from your laptop.
