It's Thursday, September 17, and here are the answers to yesterday's Cisco practice exam questions!

Be sure to check today's other blog posts for links to my new YouTube videos and video channel!

SW2# ?
VTP Version : 2

Answer: That's the output of an excellent first step in VTP troubleshooting - show vtp status.



CCNA Security Certification / CCNP ISCW Exam:

Briefly describe a man-in-the-middle attack and propose at least one solution for this network attack.

Answer: Basically, a potential network intruder eavesdrops on a conversation between "Point A" and "Point B", then contacts each of those points individually and pretends to be the other point.

Two sound defenses against MITM attacks are the use of a Certification Authority (CA) and using cryptography to protect the initial conversation.

B. No number needs to be dialed to reach the destination

C. Dynamically creates dial peer statements for POTS configurations only

D. Dynamically created session target statements for VOIP configurations only

Answer: B. The Private-Line Automatic Ringdown (PLAR) allows a call to be placed with no dialing necessary - the call is placed simply by picking up the line.



CCNP Certification / BSCI Exam:

Short answer: What is the OUI of any multicast MAC address?

Answer: The MAC OUI of a multicast address is 01-00-5e.



CCNP Certification / BCMSN Exam:

A. It's Cisco-proprietary

B. Non-Cisco vendors cannot support LEAP in any way

C. Uses strong one-way authentication

D. Uses a RADIUS server

Answer: A, C, D. LEAP is a Cisco-proprietary protocol, but third-party vendors can support it via the Cisco Compatible Extensions program. The client and the RADIUS server will authenticate each other, resulting in strong two-way authentication.
