It's Sunday, June 29, and here are the answers to yesterday's Cisco practice exam questions!

Be sure to read yesterday and today's blog postings to read all about the exciting opportunity to earn the new CCNA Security, Voice, and Wireless certifications!


Short answer: What do the letters "IA" indicate in an OSPF routing table?

Answer: "IA" indicates an inter-area route - a route to a destination in another OSPF area.


Short answer: Cisco OSPF design guidelines suggest a router have no more than ____________ neighbors.

Answer: Cisco suggests a single OSPF-enabled router have no more than 60 neighbors.


Short answer: Identify and briefly describe the dot1x port authentication modes.

Answer: The dot1x port authentication modes are auto, force-authorized (the default), and force-unauthorized. Force-authorized means the port is always authorized; force-unauthorized means the port can never be authorized; ports in auto transmit EAP packets and become authorized only when the authentication server allows it.


Identify the true statements.

A. RADIUS considers each "A" in AAA to be a separate process.

B. TACACS+ considers each "A" in AAA to be a separate process.

C. TACACS+ is capable of encrypting the entire packet.

D. RADIUS is capable of encrypting the entire packet.

Answer: B, C. RADIUS actually combines the authentication and authorization processes, making it very difficult to run one but not the other. Also, While TACACS+ encrypts the entire packet, RADIUS encrypts only the password in the initial client-server packet.


What are the four pre-defined priority levels in WiFi Multimedia?

Answer: Platinum (for voice), Gold (for video), Silver (for everything else - best-effort)
and Bronze (background traffic).

New questions posted later today!

To your success,
