Here are the answers to Friday's Cisco certification practice questions!

CCNA:

You have configured frame relay on an interface, and this interface is shut. You have decided to use Cisco's dynamic frame mapping feature. What is the minimum configuration necessary?

A. Enable ARP on the interface and open it.

B. Enable IARP on the interface and open it.

C. Enable RARP on the interface and open it.

D. Open the interface and do nothing else.

Answer: D. The feature we want to use here is Inverse ARP (IARP), but that's enabled by default - all you have to do is open the interface.


CCNP / BSCI:

Short answer: After route summarization is configured, the router on which summarization is configured will have an extra route. To what interface or destination does this new route point?

Answer: This summary route will point to Null0.


CCNP / BCMSN:

What DSCP codepoint name is the highest level of service available for user traffic?

A. AF

B. EF

C. CD

D. DP

Answer: B. Expedited Forwarding (EF) is the highest level of service available for user traffic. It's not the highest level overall, though. This is level 5, and 6-7 are reserved for network control traffic.
