Here are the answers to the Cisco certification practice exam questions posted Saturday, October 4!

Look for new CCNA / CCNP videos in today's posts, and I'll have a new CCNA Security exam tutorial for you on Tuesday!


CCNA Certification And CCENT Certification:

You want to make sure your RIP deployment supports routing packet update authentication. What command should you place in the below configuration?

R1(config)#router rip
R1(config-router)# ?
R1(config-router)#network 172.12.123.0
R1(config-router)#network 1.0.0.0


Answer: Since only version 2 supports RIP packet update authentication, you could hardcode your router to send and accept only version 2 updates with the version 2 command.


CCNA Security Certification / CCNP ISCW Exam:

What command resulted in the following output?

HQ# ?
Configured SDF Locations:
flash://256MB.sdf
Builtin signatures are enabled but not loaded
Last successful SDF load time: 14:17:00 UTC May 16 2008
IPS fail closed is disabled


Answer: show ip ips config.



CCNP Certification / BSCI Exam:


Which of the following will always be present in a BGP routing update?

A. AS_PATH

B. Local Preference

C. origin

D. MED

E. atomic aggregate

Answers: A, C. Those are the only two mandatory attributes listed. next-hop is also mandatory.



CCNP Certification / BCMSN Exam:

Name two different methods of resetting a Cisco switch's configuration revision number to zero.

Answer: Theory holds that there are two ways to reset a switch's revision number to zero:

Change the VTP domain name to a nonexistent domain, then change it back to the original name.
Change the VTP mode to Transparent, then change it back to Server.


Reloading the switch won't do the job, because the revision number is kept in NVRAM, and the contents of Non-Volatile RAM are kept on a reload.


CCNP / ONT Exam:

Identify the true statements regarding traffic policing.

A. Traffic is policed in the outbound direction only

B. Traffic can be policed in either the inbound or outbound direction

C. Generally has more TCP retransmissions than traffic shaping

D. Usually has fewer TCP retransmissions than traffic shaping

E. Supports traffic marking

F. Does not support traffic marking

Answers: B, C, E.

More questions right here later today!
