Q&A

As mentioned in the introduction, "All About the CCNP, CCDP, and CCIP Certifications," you have two choices for review questions. The questions that follow next give you a bigger challenge than the exam itself by using an open -ended question format. By reviewing now with this more difficult question format, you can exercise your memory better and prove your conceptual and factual knowledge of this chapter. The answers to these questions are found in Appendix A.

For more practice with examlike question formats, including questions using a router simulator and multichoice questions, use the exam engine on the CD-ROM.

1:	In the routing table, a field indicates the source of the routing information. If the field showed the letter C, what would this mean?
2:	In the routing table, how is the next hop indicated?
3:	Cisco distinguishes between the routing and the switching functions. What is the difference?
4:	Name the interior IP routing protocols that send the mask with the routing update.
5:	Does VLSM require a classful or classless routing protocol, and why?
6:	State one of the characteristics of a classful routing protocol.
7:	What is the command to show whether a specific network, such as 141.131.6.16, is present in the routing table?
8:	State one major difference between a classful protocol and a classless routing protocol.
9:	Describe briefly the difference between a routing and routed protocol.
10:	Describe the processes used to build and maintain the routing table.
11:	Give a brief explanation of the switching function.
12:	What information is contained in the fast switching cache?
13:	When would you use the command no auto-summary ?
14:	When does OSPF send updates, and do they contain the entire routing table?
15:	Network convergence is when a network domain has learned about the new network topology after a change has occurred in the domain. What is considered a network change that would require network convergence?
16:	When would you consider using a static route in your network?
17:	When would you consider using a default route in your network?
18:	What command is used to configure ODR on a hub router?
