It's Monday, November 17, and it's time for the answers to Saturday's Cisco practice exam questions!

My apologies to you BCMSN students, I left the question out for that exam on Saturday. I'll make it up to you on Monday!

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:

What type of BPDU triggers an interface's defenses when that interface is configured with Root Guard?

A. A superior BPDU


C. BPDUs from an err-disabled router

D. A BPDU that would result in a change in the STP topology

Answer: A, D. Root Guard protects against a superior BPDU coming in on a given port, and it's superior BPDUs that would indeed change the STP topology.

CCNA Security Certification / CCNP ISCW Exam:

What's the main difference between a DoS attack and a DDoS attack?

Answer: A Distributed DoS attack uses multiple attack sources (usually zombie computers), where a "regular" DoS attack has a single attack source.

CCNP Certification / BSCI Exam:

The EIGRP Feasible Successor appears in which of the following tables?

A. Successor

B. Neighbor

C. Route

D. Topology

Answer: D. This route type appears only in one EIGRP table, the Topology table.

CCNP / ONT Exam:

What SDM Task button should you click to begin configuring a QoS scheme?

Answer: The QoS button, naturally!

More questions for you right here later today, and I'll have a new CCNA or CCNP video here on the blog and in YouTube beginning Tuesday - at least 35 new videos by the end of the year!

To your success,

Chris Bryant
