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.
