  15. Introduction 1 Introduction MCSE Training Guide: TCP/IP is designed for advanced end-users, service technicians, and network administrators who are consider- ing certification as a Microsoft Certified Systems Engineer (MCSE), Microsoft Certified Product (MCP) Specialist or as a Microsoft Certified Solution Developer (MCSD). The TCP/IP exam (Exam 70-59: “Internetworking with Microsoft TCP/IP on Microsoft Windows NT 4.0”) tests your ability to implement, ad- minister, and troubleshoot information systems that incorporate TCP/IP as well as your ability to provide technical support to us- ers of Microsoft Windows NT employing TCP/IP protocols. Who Should Read This Book This book is designed to help advanced users, service technicians, and network administrators who are working for MCSE certifica- tion prepare for the MCSE “Internetworking with Microsoft TCP/ IP on Microsoft Windows NT 4.0” exam (#70-59). This book is your one-stop-shop. Everything you need to know to pass the exam is in here, and Microsoft has certified it as study material. You do not need to take a class in addition to buying this book to pass the exam. However, depending on your personal study habits or learning style, you may benefit from taking a class in addition to the book or buying this book in addition to a class. This book also can help advanced users and administrators who are not studying for the MCSE exam but are looking for a single- volume reference on TCP/IP implementation.
  16. 2 MCSE Training Guide: TCP/IP How This Book Helps You This book takes you on a self-guided tour of all the areas covered by the MCSE TCP/IP exam and teaches you the specific skills you need to achieve your MCSE certification. You’ll also find helpful hints, tips, real-world examples, exercises, and references to addi- tional study materials. Specifically, this book is set up to help you in the following ways: Objective . Organization. This book is organized by major exam topics. Every objective you need to know for the “Internetworking with Microsoft TCP/IP on Microsoft Windows NT 4.0” exam is covered in this book; we’ve include a margin icon, like the one in the margin here, to help you quickly locate these objectives. There are pointers at different elements to direct you to the appropriate place in the book if you find you need to review certain sections. . Deciding how to spend your time wisely. Pre-chapter quizzes are at the beginning of each chapter to test your knowledge of the objectives contained within that chapter. If you already know the answers to those questions, you can make a time- management decision accordingly. . Extensive practice test options. Plenty of questions are at the end of each chapter to test your comprehension of material covered within that chapter. An answer list follows the ques- tions so you can check yourself. These practice test options will help you decide what you already understand and what requires extra review on your part. The CD-ROM also con- tains a sample test engine that will give you an accurate idea of what the test is really like. You’ll also get a chance to practice for the certification exams using the test engine on the accompanying CD-ROM. The ques- tions on the CD-ROM provide a more thorough and comprehen- sive look at what your certification exams really are like.
  17. Introduction 3 Note For a complete description of New Riders’ newly-developed test engine, please see Appendix D, “All About TestPrep.” For a complete description of what you can find on the CD- ROM, see Appendix C, “What’s on the CD-ROM.” For more information about the exam or the certification process, contact Microsoft at: Microsoft Education: Call (800) 636-7544 Internet: ftp://ftp.microsoft.com/Services/MSEdCert World Wide Web: http://www.microsoft.com/train_cert/ default.htm CompuServe Forum: GO MSEDCERT Understanding What the “Internetworking with Microsoft TCP/IP on Microsoft Windows NT 4.0” Exam (#70-59) Covers The “Internetworking with Microsoft TCP/IP on Microsoft Win- dows NT® 4.0” exam (#70-59) covers five main topic areas, ar- ranged in accordance with test objectives. On the CD-ROM that comes with this book, you’ll find document lpr70-59.doc, which is the exam preparation guide prepared by Microsoft. lpr70-59.doc describes what you will be tested on and suggests ways to prepare for the exam. The exam objectives, listed by topic area, are cov- ered in the following sections.
  18. 4 MCSE Training Guide: TCP/IP Hardware and Software Needed As a self-paced study guide, much of the book expects you to use Windows NT Server and follow along through the exercises while you learn. Microsoft designed their implementation of TCP/IP to operate in a wide range of actual situations, and the exercises in this book encompass that range. However, the exercises require only a single stand-alone Windows NT computer running TCP/IP Server. The computer should meet the following criteria: . Computer on the Microsoft Hardware Compatibility List . 486DX2 66-Mhz (or better) processor for Windows NT Server . 16 MB of RAM (minimum) for Windows NT Server . 340-MB (or larger) hard disk for Windows NT Server . 3.5-inch 1.44-MB floppy drive . VGA (or Super VGA) video adapter . VGA (or Super VGA) monitor . Mouse or equivalent pointing device . Two-speed (or faster) CD-ROM drive (optional) . Network Interface Card (NIC) . Presence on an existing network, or use of a 2-port (or more) mini-port hub to create a test network . MS-DOS 5.0 or 6.x and Microsoft Windows for Workgroups 3.x preinstalled . Microsoft Windows 95 (floppy version) . Microsoft Windows NT Server (CD-ROM version) It is somewhat easier to get access to the necessary computer hard- ware and software in a corporate business environment. It is hard- er to allocate enough time within the busy workday to complete a self-study program. Most of your study time may occur after nor- mal working hours, away from the everyday interruptions and pressures of your regular job.
  19. Introduction 5 Tips for the Exam Remember the following tips as you prepare for the MCSE/MCSD certification exams: . Read all the material. Microsoft has been known to include material not specified in the objectives. This course has in- cluded additional information not required by the objectives in an effort to give you the best possible preparation for the examination, and for the real-world network experiences to come. . Complete the exercises in each chapter. They will help you gain experience using the Microsoft product. All Microsoft exams are experienced-based and require you to have used the Microsoft product in a real networking environment. Exercises for each objective are placed at the end of each chapter. . Take each pre-chapter quiz to evaluate how well you know the topic of the chapter. Each chapter opens with one essay question per exam objective covered in the chapter. Follow- ing the quiz are the answers and pointers to where in the chapter that objective is covered. . Complete all the questions in the “Review Questions” sec- tions. Complete the questions at the end of each chapter— they will help you remember key points. The questions are fairly simple, but be warned, some questions may have more than one answer. . Review the exam objectives in the Microsoft Preparation Guide. Develop your own questions for each topic listed. If you can make and answer several questions for each topic, you should pass.
  20. 6 MCSE Training Guide: TCP/IP Note Although this book is designed to prepare you to take and pass the “Internetworking with Microsoft TCP/IP on Microsoft Windows NT 4.0” certification exam, there are no guarantees. Read this book, work through the exercises, and take the practice assessment exams. When taking the real certification exam, make sure you answer all the questions before your time limit expires. Do not spend too much time on any one question. If you are unsure about an answer, answer the question as best you can and mark it for later review when you have finished all the questions. It has been said, whether correctly or not, that any questions left un- answered will automatically cause you to fail. Remember, the object is not to pass the exam, it is to understand the material. Once you understand the material, passing is simple. Knowledge is a pyramid; to build upward, you need a solid foun- dation. The Microsoft Certified System Engineer and Solution Developer programs are designed to ensure that you have that solid foundation. Good luck!
