It's Saturday, November 15, and it's time for us to take a look at the answers to Thursday's Cisco practice exam questions!

I posted quite a few new free Cisco training videos this past week, with over 30 more to come over the next six weeks - be sure to subscribe to my YouTube channel to be the first to know of new videos! Details in today's other blog posts!

CCNA Certification And CCENT Certification:

You're connecting two Cisco 2950 switches, and you want to create a trunk between them. What cable is required? Also, assuming the switches are at their defaults, what additional commands are needed to create the trunk?

Answer: You'll need a crossover cable. If the 2950s are at their defaults, you will need no additional commands as the ports will attempt to form a trunk dynamically.

That can present a security issue, which brings us to our next question!

CCNA Security Certification / CCNP ISCW Exam:

In the scenario presented in the above question, name three security features or practices you should consider configuring to prevent a rogue switch gaining access to your network.

Answer: You should consider using Root Guard, Port Guard, or using a unused VLAN as the default VLAN on the trunk.

You could also disable the transmission of Dynamic Trunking Protocol (DTP) frames.

CCNP Certification / BSCI Exam:

The variance command changes which of the following EIGRP values?

A. Advertised Distance

B. Feasible Distance

C. Both of these

D. Neither of these

Answer: D. The variance command doesn't actually change either of those values. Watch your routing tables the next time you run an EIGRP lab and you'll see this!

CCNP / ONT Exam:

You have a PDLM file in Flash, ccnp.pdlm, that you'd like to load as part of your NBAR configuration. What command will do this?

Answer: Loading a PDLM (assuming the PDLM is in Flash) :

R2(config)#ip nbar pdlm ?

WORD Full path of the PDLM file

R2(config)#ip nbar pdlm flash://ccnp.pdlm

New questions later today!

To your success,
