CCNP routing exam cram

CCNP routing exam cram

Eric Mcmasters, Brian Morgan, Mike Shroyer

400 pages, parution le 15/08/2000

Résumé

Prepares the reader to pass the new CCNP Routing exam (640-503). Instructs the reader on ways to configure the Cisco IOS software for scalable operation in large or growing multiprotocol internetworks. Contains exclusive tear-out cram sheet with tips, acronyms, and memory-joggers (mnemonics) to improve recall immediately before the exam. Includes sections on proven test-taking strategies, warnings on trick questions, time-saving study tips, multiple-part question strategies, and shortcuts.

Each topical Exam Cram chapter follows a regular structure, along with graphical cues about important or useful information. Here?s the structure of a typical chapter: ? Opening hotlists?Each chapter begins with a list of the terms, tools, and techniques that you must learn and understand before you can be fully conversant with that chapter?s subject matter. The hotlists are followed by one or two introductory paragraphs to set the stage for the rest of the chapter. ? Topical coverage?After the opening hotlists, each chapter covers a series of at least four topics related to the chapter?s subject. Throughout this section, topics or concepts likely to appear on a test are highlighted using a special Exam Alert layout, like this: This is what an Exam Alert looks like. Normally, an Exam Alert stresses concepts, terms, software, or activities that are likely to relate to one or more certification test questions. For that reason, any information found offset in Exam Alert format is worthy of unusual attentiveness on your part. Indeed, most of the information that appears on the Cram Sheet appears as Exam Alerts within the text.

You?ll find what appears in the meat of each chapter to be worth knowing, too, when preparing for the test. Because this book?s material is very condensed, we recommend that you use this book along with other resources to achieve the maximum benefit.

In addition to the Exam Alerts, we have provided tips that will help build a better foundation for routing knowledge. Although the information may not be on the exam, it is certainly related and will help you become a better test taker.

This is how tips are formatted. Keep your eyes open for these, and you?ll become a Cisco internetworking expert in no time!

  • Practice questions?Although we talk about test questions and topics throughout the book, a section at the end of each chapter presents a series of mock test questions and explanations of both correct and incorrect answers. We also try to point out especially tricky questions by using a special icon, like this:
Ordinarily, this icon flags the presence of a particularly devious inquiry, if not an outright trick question. Trick questions are calculated to be answered incorrectly if not read more than once, and carefully, at that. Although they?re not ubiquitous, such questions make regular appearances on the Cisco exams. That?s why we say exam questions are as much about reading comprehension as they are about knowing your material inside out and backwards.
  • Details and resources?Every chapter ends with a section titled "Need to Know More?" It provides direct pointers to Cisco and third-party resources offering more details on the chapter?s subject. In addition, this section tries to rank or at least rate the quality and thoroughness of the topic?s coverage by each resource. If you find a resource in this collection that you like, use it, but don?t feel compelled to use all the resources. On the other hand, we recommend only resources we use regularly, so none of our recommendations will be a waste of your time or money (but purchasing them all at once probably represents an expense that many network administrators and would-be CCNPs might find hard to justify).
The bulk of the book follows this chapter structure slavishly, but there are a few other elements that we?d like to point out. Chapter 14 is a sample test that provides a good review of the material presented throughout the book to ensure you?re ready for the exam. Chapter 15 is the answer key. In addition, you?ll find a handy glossary and an index.

Finally, the tear-out Cram Sheet attached next to the inside front cover of this Exam Cram book represents a condensed and compiled collection of facts, figures, and tips that we think you should memorize before taking the test. Because you can dump this information out of your head onto a piece of paper before answering any exam questions, you can master this information by brute force?you need to remember it only long enough to write it down when you walk into the test room. You might even want to look at it in the car (not while driving) or in the lobby of the testing center just before you walk in to take the test.
