Answers:

1. logging synchronous forces the router to hold console messages until no data input is detected.

 

2. "D". The console makes it look as though you have to use the dollar sign or a capital C, but you can choose your own delimiting character.

 

3. "A". By default, incoming Telnet connections are placed into user exec mode. To move into privileged exec mode, the user will have to know the enable password, OR.....

 

4. .... you can use the privilege level 15 command on the VTY lines to place incoming Telnet connections directly into privileged exec mode without the user being prompted for the enable password.

 

5. username/password, as in:

username jbrisco password nwachamp

username captharris password cornelia

You can also assign a privilege level on a per-user basis with this command.

 

6. To use that local database for Telnet authentication, use the login local command on the VTY lines.

 

7. "D". The vlan1 interface is also called the switch management interface.

 

8. ctrl-a moves your cursor to the front of the line. This keystroke makes putting the word "no" in front of a long command much easier, as illustrated in the video on this page.

 

9. Use the interface range command. It's a little tricky at first, but take a little time to get used to it.. it'll really come in handy one day.

 

10. That's the exec-timeout 0 0 command (both zeroes). This isn't always a welcome command on production networks, but it's a great home lab command.
