Welcome back! Here are the answers to Monday's Cisco certification exam practice questions!

CCNA:

R1 and R3 are connected via a DTE/DCE cable, both routers using interface serial1. What additional command is needed to make the line protocol come up?

A. On the DTE, configure clockrate 56000.

B. On the DCE, configure clockrate 56000.

C. On the DTE, configure clockrate 56.

D. On the DCE, configure clockrate 56.

Answer: B. Use show controller serial x to determine the DCE, then configure clockrate 56000 on that serial interface.


CCNP / BSCI:

Which of the following OSPF network types are RFC compliant for use over an NBMA topology?

A. point-to-point

B. point-to-multipoint broadcast

C. point-to-multipoint non-broadcast

D. broadcast

E. NBMA

Answers: B, E. Both point-to-multipoint broadcast and NBMA are RFC compliant for that network topology. The others are not illegal, just not officially compliant.


CCNP / BCMSN: Short answer: Users are complaining of slow access to network services when they first log in to the network. Some are having problems receiving their dynamically assigned IP addresses. What Cisco switching feature can help?


Answer: Portfast can help here as well, allowing users to avoid the listening and learning states of Spanning Tree.


See you later today with brand-new questions!
