Chris Bryant, CCIE #12933

Here's the second in a series of CCNA Frame Relay exams - and if you missed the first, hit the link at the end of this exam!

When you're done here, visit my CCNA Tutorials and CCNA 3-Minute Boot Camp pages... and there's plenty of CCNP material on those pages, too.

You'll also find links to the "CCNA Practice Exam Of The Day" on the Bulldog Blog!

Let's get to the questions!

1. What term describes the use of the same DLCI number at multiple points in your network?

2. What's the minimum configuration needed to enable dynamic Frame Relay mapping on a Cisco router serial interface? Assume the interface has not yet been opened.

A. Enable inverse ARP and open the interface.

B. Enable ARP and open the interface.

C. Enable reverse ARP and open the interface.

D. Just open the interface.

3. What command will disable the dynamic mapping mentioned in the previous question?

4. Identify the true statements regarding the following command:

frame-relay map ip 172.1.1.2 212

A. The "212" is the local router's DLCI.

B. The "212" is the remote router's DLCI.

C. This interface will be configured at the global level.

D. This interface will be configured at the interface level.

E. Routing protocol hello traffic could be sent successfully with this statement.

5. What is the default encapsulation type on a Cisco router serial interface?

A. PPP

B. Ethernet

C. HDLC

Answers:

1. That's global addressing.

2. "D". You'll use Inverse ARP for dynamic frame relay mapping, and that's enabled by default - all you need to do is open the interface!

3. To disable Inverse ARP, you'll need the interface-level command no frame-relay inverse-arp.

4. "A, D". The DLCI is always the local router's DLCI, and the frame map command is an interface-level command. (Hello traffic will not be passed successfully if the broadcast option is left off the command, as it was here.)

5. "C". We've been talking about Frame Relay here, but the default encapsulation on a Cisco serial interface is HDLC.
