Chris Bryant, CCIE #12933

Here's a CCNA Practice Exam to help you master these tough Cisco router configs, and when you're done here, be sure to visit that page!

Let's get started!

1. You're going to connect your laptop physically to a Cisco router with a rollover cable. You need to know which of the following passwords at a minimum to access the router?

A. VTY password

B. console line password

C. async line password

D. enable password

 

2. You're connecting to a Cisco router via Telnet. The Telnet configuration on that router has the login and password commands configured, and no others.

The only password you know on that router is the VTY password. Which of the following describes what the result will be?

A. You'll be unable to authenticate and no further action will be taken by the router

B. You'll be able to authenticate, but not enter enable mode

C. Upon authentication, you'll be able to configure the router immediately

D. You'll be unable to authenticate and an SNMP trap will be triggered

 

3. You're configuring a Cisco router in a job interview. The interviewer asks you to change all of the port settings on a 2950 switch to half-duplex with a single command. What's your next move?

A. Politely inform the interviewer that this cannot be done

B. Use the interface range command

C. Use the global switch command

D. Use the duplex all half command

4. Which of the following, if any, require a restart of the router or of a process running on the router in order to take effect?

And here's a full HOUR of free training from my course!

And now -- the answers!

1. (B). You'll need to know the console port password in order to get into the router.

 

2. (B). In this scenario, you know the VTY password, so you can authenticate via Telnet.

The question mentions that the privilege level command has not been configured on the VTY lines, so the default behavior will be to let you in if you know the VTY password, but you won't be able to enter enable mode.

You'd need to know the enable password for that, and the question mentions that you don't know any other passwords.

 

3. (B). You can use the time-saving and point-earning command interface range command for that.

 

4. (C). The only one of those tasks that requires a restart of the router or the routing process is changing the OSPF RID.

I'll have more CCNA scenario-based questions for you in the VERY near future.
