- Final Network Scenario From: CLSC Exam Certification Guide

15. Final Network Scenario

This chapter is designed to assist you in final preparation for the CLSC exam. It presents a case study and its solution involving the move from a traditional collapsed backbone to a flatter, switched network using Catalyst switches and ATM LANE modules. Interspersed throughout this chapter are questions that test your knowledge of the material. In addition, we provide some configurations and the results of some show commands related to this network. Keep in mind that although the Cisco LAN Switch Configuration (CLSC) exam contains no scenarios of this type, the real-world applicability and skill used when analyzing this case study will strengthen your knowledge base.

As we just mentioned, this is the final preparation phase before you take your exam. If you want even more final preparation, you can read through the many practice questions located in each chapter and on the CD-ROM. You can find the answers to all pre-chapter quiz and chapter-ending questions in Appendix A, “Answers to 'Do I Know This Already?' Quizzes and Q & A Sections.” You can read and review these conveniently located questions and their explanations quickly. In addition, the CD-ROM has testing software, as well as many additional questions in the multiple-choice format of the CLSC exam. These questions should be a valuable resource when performing final preparations.

How to Best Use This Chapter

These scenarios focus on easily forgotten items, the first of which involves the show commands. The options of these commands are often ignored, mainly because we can get online help about the correct option easily when using the Cisco CLI. However, questions about the exact command options used to see a particular piece of information are scattered throughout the exam. Take care to review the output of the commands in these scenarios.

This chapter also focuses on a review of command-line tricks and acronym trivia. Like it or not, part of the preparation involves memorization; hopefully, these reminders will save you a question or two on the exam!

Finally, more configurations are shown for almost all options already covered in the book. If you can configure these options without online help, you should feel confident that you can choose the correct command from a list of five options in a multiple-choice question.

Many of you will read this chapter as your final review before taking the exam; let us take this opportunity to wish you success. We hope that you will be relaxed and confident for your exam, and we trust that this book has helped you build your knowledge and confidence.
