The candidates attempting the CLSC exam must possess the skills to perform the following tasks: • Describe the major features of the Catalyst switches • Describe the architecture and functions of the major components of the Catalyst switches • Place Catalyst series switches in a network for optimal performance benefit • Use the command-line or menu-driven interface to configure the Catalyst series switches and their switching modules • Use the command-line or menu-driven interface to configure trunks, virtual LANs, and ATM LAN Emulation • Maintain Catalyst series switches and perform basic troubleshooting Suggested Cisco Training Paths for Prior Preparation This book assumes that you have a familiar level of understanding of the CLSC objectives, through either the CLSC course or an equivalent level of on-the-job training, and that you are now ready to master the CLSC exam objectives and become a CCNP or CCDP. Table 1-1 outlines the three training paths you can take to become a CCNP, including the various courses available. 35708754 CH01.book Page 3 Wednesday, August 25, 1999 9:27 PM 4 Chapter 1: The Cisco LAN Switch Configuration (CLSC) Exam Overview The CCDP training path is the same as the CCNP path, but it substitutes a Cisco Internetwork Design (CID) course and exam for the Cisco Internetworking Troubleshooting (CIT) course and exam. CLSC Exam Philosophy The exam objectives create a great tool for preparation. If you are going to prepare only slightly, making sure that you can address all objectives is an obvious thing to do. However, what each objective means, and the breadth of questions that could be asked based on an individual objective, is open to interpretation. This book generally follows the CLSC course to determine the depth of coverage for various objectives. A full definition of exactly what topics are on the exam will probably never be stated by Cisco. Cisco does want candidates to succeed at passing the CLSC exam, but not at the expense of making the Cisco career certification an easily attained paper diploma. Cisco’s goal is that passing the CLSC exam should reflect the fact that you have internalized and mastered the concepts, not that you can read a book and memorize well. To protect against the CCDP and CCNP losing credibility due to people just reading a book and passing the test, Cisco will probably always avoid an exact definition of the topics on the exam. Giving a general definition only will reward those who understand networks; those who prefer to memorize will be less likely to pass the test. Table 1-1 Training Paths for Becoming a CCNP Training Path What Is Involved 1 CCNP Path As defined by Cisco Systems, this involves taking these courses: Advanced Cisco Router Configuration (ACRC) Cisco LAN Switch Configuration (CLSC) Configuring, Monitoring, and Troubleshooting Dialup Services (CMTD) Cisco Internetworking Troubleshooting (CIT) The candidate then would take a test for each class attended. (Note that the ACRC, CLSC, and CMTD exams can be taken all together as the Foundation Routing and Switching [FRS] exam.) 2 On-the-job training The courses are not required to take the exams, but the exams require a large amount of specific knowledge. Candidates who have not taken the courses should use this book to make sure they are familiar with all the objectives. When the candidate is familiar with the exam objectives, he or she would take the same exams listed at the bottom of Step 1. 35708754 CH01.book Page 4 Wednesday, August 25, 1999 9:27 PM CLSC Exam Preparation 5 Naturally, the objectives will change as time goes on. As this happens, a higher percentage of the test questions will not be in the list of objectives found in this book. Of course, Cisco will change or add to the objective list at its discretion, so pulling the latest CLSC objectives list from Cisco’s web site (http://www.cisco.com) is worth the effort. The CLSC exam topics will closely match what is covered in the recommended prerequisite training course. Cisco Worldwide Training (WWT) is the Cisco organization with responsibility for the certifications. Many of the certification exams evolved from exams covering a particular course. It is reasonable to expect, with good benefits to us, that CLSC and the other certifications will cover the topics in the prerequisite classes. The following list encapsulates the basic philosophy behind preparing for the CLSC exam, based on what Cisco is willing to disclose: • While open to interpretation, the CLSC objectives define the main topics covered on the exam. At a minimum, you should know about each subject covered in these objectives. • The depth of knowledge on each topic is comparable to what is covered in the prerequisite courses. The book attempts to cover the topics to a slightly deeper level, to make sure you know more than enough. • Getting the latest copy of Cisco’s CLSC objectives from the company’s web site (http://www.cisco.com) is very useful. Comparing that list to the one used for this book will let you know the topics you will need to spend additional time studying. • Do not expect to pass the exam if your only preparation has been to read this book. Use one of the suggested training paths, and work with routers and switches for the best chance at success. CLSC Exam Preparation This book contains many solid tools to help you prepare for the CLSC exam. Some of the key features to help you are outlined in the next few sections. Chapters Follow the Objectives Each chapter clearly follows the CLSC exam objectives so that you can stay on track with the material that will be covered in the exam. You’ll know clearly what objective each section is covering. 35708754 CH01.book Page 5 Wednesday, August 25, 1999 9:27 PM 6 Chapter 1: The Cisco LAN Switch Configuration (CLSC) Exam Overview Determining Your Strengths and Weaknesses You may feel confident about one topic and less confident about another. However, that may be a confidence problem, not a knowledge problem! One key to using your time well is to determine whether you truly need more study or not—and if so, how much? The chapters are designed to guide you through the process of determining what you need to study. Suggestions are made as to how to study a topic based on your personal strengths. Each chapter begins with a quiz that helps you decide how well you recall the topics in that chapter. From there, you can choose to fully read the entire chapter, to ignore that chapter because you know it already, or something in between. Much of the factual information is summarized into lists and charts in the Foundations Summaries sections, so a review of the chapter is easy. Also, exercises at the end of the chapter provide an excellent tool for practice and for quick review. Questions and Exercises That Are Harder Than the Actual Exam The exercises in this book are intended to make you stretch beyond what the exam requires. Do not be discouraged as you take the quizzes and exercises in the book; they are intended to be harder than the exam. If, by the end of your study time, you are getting 70 or 80 percent of these harder non-multiple choice questions correct, you should find the CLSC exam easier to handle. You will probably want to validate your readiness by using the testing engine included on the CD-ROM with this book. The main purpose for making this book’s exams harder than the CLSC exam is not by asking for facts or concepts you will never see on the CLSC exam; it is by asking for information in ways that will not imply the correct answer. You will get some questions correct on the CLSC exam just because the multiple answers will trigger your memory to the correct information. By answering questions that are not multiple choice, however, and by providing the same information in different ways, you will exercise your memory so that the multiple choice exam is easy! Simulated Testing on the CD-ROM Of course, if you never practice using actual exams, you will not be fully prepared. The test engine on the CD-ROM can be used in two ways to help you prepare for the actual test. First, it will give you a timed test of the same length as the actual CLSC exam and will score the exam for you. Secondly, you can tell the tool to feed you questions on a particular subject so that you can do some intensive review. 35708754 CH01.book Page 6 Wednesday, August 25, 1999 9:27 PM The CLSC Exam Objectives 7 The CLSC Exam Objectives Cisco System’s published CLSC exam objectives are currently listed on Cisco’s web site (http://www.cisco.com).
