Appendix E, which is also on the CD-ROM, contains all the tables and lists and can be used to check your answers. 14.3.3 Referencing Commands in this Chapter and Testing Memory Table 14-5 and Table 14-6 include references to configuration and EXEC commands that appear in this chapter; it is not necessary to memorize the contents of the table here; in fact, you should be able to remember these commands after reading the chapter and completing all of the exercises in the Exam Preparation section of the chapter. To verify your learning, you can test to see if you remember these commands by covering the left side of the table and then reading the instructions on the right side of the table to see if you can remember the corresponding commands.

Unlike most of the other chapters in this book, this chapter introduces each topic briefly and then moves on to the next topic, focusing on introducing you to the basic ideas behind a handful of other WAN protocols. To provide an introduction to these technologies, this chapter will be divided into two main sections. The first section focuses on WAN technologies that create private WAN services for the enterprise. The second part looks at WAN technology that is used to access the Internet and that can be used for both enterprises and customers. 15.1 Do I Know This Already?" QuizThe quizzes in this section allow the reader to determine if it is necessary to skim the chapter or a major section, or even to read the chapter's "test prep" directly.
