Here are the answers to Thursday's Cisco certification exam questions!

CCNA Certification:

On the blank console line shown below, what command should be used to prevent OSPF hellos from keeping the ISDN line up?

R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#interface bri0
R2(config-if)#

Answer: ip ospf demand-circuit will allow the OSPF adjacency over the BRI link to remain intact while not allowing the OSPF hello packets to keep the line up.


CCNP Certification / BSCI Exam:

By default, how does an OSPF routing table indicate routes that were learned by the OSPF domain via redistribution?

Answer: By default, those routes are marked "E2".


CCNP Certification / BCMSN Exam:

A switch has two paths to the root bridge. One is direct, the other goes through another switch. You want to lessen the delay that will occur if the current root port goes down. What Cisco feature can help?

Answer: Uplinkfast can help. When the root port goes down, the currently blocked port will be placed info forwarding mode almost immediately.



CCNP Certification / ISCW Exam:

Users who telnet successfully into your router should be placed directly into privileged exec mode. What command will accomplish this?

Answer: Use the command privilege level 15 under the VTY lines.




CCNP Certification / ONT Exam:

You're working with a serial interface set to T1 speed. By default, what queueing scheme is running on that interface?

Answer: Weighted Fair Queueing (WFQ) runs on interfaces running at less than 2.048 MBPS speed, which is E1.

See you later today with lots more, including new Cisco certification exam practice questions!

To your success,
