To help you prepare for total success on your Cisco certification exams, here are some free practice exam questions on topics from Proxy ARP to honeypots. Answers are at the bottom of the page. Enjoy!

CCNA Security Certification / CCNP ISCW Exam:
In terms of network security, what purpose does a honeypot serve?
CCNP Certification / BSCI Exam:
In the following output, describe ….
1. The meaning of "EX"
2. The value replaced by the question mark
3. The default setting of the value replaced by the question mark
4. The meaning of "2195456"

Hardware is EtherSVI, address is 0012.7f02.4b42 (bia 0012.7f02.4b42)
Internet address is 188.8.131.52/24
CCNP / ONT Exam:
What modules allow you to extend NBAR capabilities without having to reload the router or update the IOS?
Here are the answers!
CCNA: The interface-level command no ip proxy-arp.
CCENT: Overhead. There's much more overhead to using TCP as compared to UDP.
CCNA Security / ISCW: 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 / BSCI: Answer:
1. The "EX" indicates an external EIGRP route. External EIGRP routes are routes learned via the route redistribution process.
2 & 3. The value replaced by the "?" is 170, the default administrative distance of an external EIGRP route.
4. The second number in the brackets is the route metric.
CCNP / BCMSN: The command show interface vlan33.
CCNP / ONT: 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.
