CCENT Certification:

What single word describes a major advantage of using UDP over TCP?

Answer: Overhead. There's much more overhead to using TCP as compared to UDP.

CCNA Security Certification / CCNP ISCW Exam:

In terms of network security, what purpose does a honeypot serve?

Answer: A honeypot is a network device that is purposely left open to attack. The attack methods are then analyzed in order to develop a defense against that attack type. (Obviously, this will not be a production server!)

CCNP Certification / BSCI Exam:

CCNP Certification / BCMSN Exam:

What command resulted in the following output?

CCNP / ONT Exam:

What modules allow you to extend NBAR capabilities without having to reload the router or update the IOS?

Answer: NBAR's capabilities are continually extended through the development of Packet Description Language Modules (PDLM). Not only do these PDLMs allow your NBAR deployment to identify more and more different types of traffic, but a router reload is not necessary, and you don't need a new IOS image.

Be sure to visit my CCNA Security Certification Resource Page for the latest information on this important new Cisco certification, including a new CCNA Security practice exam and the first in a series of SDM tutorials.

I'll also have more brand-new practice exam questions for you later today!

To your success,
