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

CCNA:

Which of the following serves as a keepalive for Frame Relay circuits?

A. BE

B. LMI

C. VC

D. DLCI

E. CIR

F. BC

Answer: B. The Local Management Interface (LMI) serves as the keepalive for a frame relay circuit.

CCNP / BSCI:

Regarding policy routing, why would you create a set statement to send packets to the interface null0?

A. This enables the packets to be routed normally.

B. This causes matching packets to be dropped.

C. This causes matching packets to be placed in the slowest queue.

D. This causes matching packets to be sent to the local loopback interface, which this process refers to as "null0".

Answer: B. When packets match a route-map statement that contains "set interface null0", that causes the packets to be dropped.


CCNP / BCMSN:

What is true of a switch's port cost?

A. The cost is dependent on the speed of the port.

B. The costs is static from one switch to another.

C. The root port cost is incremented as the BPDU enters the switch.

D. The root port cost is incremented as the BPDU leaves the switch.

Answers: A, C. Port cost depends on the speed of the link. The root port cost is incremented as the BPDU enters the switch. Remember - the physically shortest path to the root is not always the logically shortest path, and that's what counts - the logical cost.

See you later today with more new Cisco certification questions!
