[3/9/2003 11:14:17] InformIT Online Books > LPI Linux Certification in a Nutshell Book: LPI Linux Certification in a Nutshell Preface Objective certification of professionals is a time-honored tradition in many fields, including medicine and law As small computer systems and networks proliferated over the last decade, Novell and Microsoft produced extremely popular certification products for their respective operating system and network technologies These two programs are often cited as having popularized a certification market where products that had previously been highly specialized and relatively rare These programs have become so popular that a huge training and preparation industry has formed to service a constant stream of new certification candidates Certification programs, offered by vendors such as Sun and Hewlett-Packard, have existed in the Unix world for some time However, since Solaris and HP-UX aren't commodity products, those programs don't draw the crowds that the PC platform does Linux, however, is different Linux is both a commodity operating system and is PC-based, and its popularity continues to grow at a rapid pace As Linux deployment increases, so too does the demand for qualified and certified Linux system administrators A number of programs the Linux Professional Institute, Sair Linux and GNU Certification, the Red Hat Certified Engineer (RHCE) program, and CompTIA's Linux+ have formed over the last few years to service this new market Each of these programs seeks to provide objective measurements of a Linux administrator's skills, but they approach the problem in different ways The RHCE program requires that candidates pass a hands-on practical skills test, solving problems and performing configuration tasks Though more involved from an exam delivery point of view, this type of test is very thorough and difficult to beat using purely good study habits The Sair program is provided by Sair, Inc., a for-profit company that is also a vendor for courseware and texts The Linux+ exam, scheduled for deployment in 2001, is an entry-level certification, which brings us to the LPI

Certification in a Nutshell Section: Preface The Linux Professional Institute The Linux Professional Institute, or LPI (http://www.lpi.org/), is a nonprofit organization formed around the notion of certifying Linux administrators through a sort of open source process The LPI seeks input from the public for its exam Objectives and questions, and anyone is welcome to participate It has both paid and volunteer staff and receives funding from some major names in the computer industry The result is a vendor-neutral, publicly developed program that is offered at a reasonable price The LPI organizes its Linux Professional Institute Certification (LPIC) series into three levels: LPIC Levels 1, 2, and Each level consists of two exams that are priced at $100 each This book covers the LPIC Level exams, numbers 101 and 102 LPI Level Exams The LPI offers its exams through Virtual University Enterprises (http://www.vue.com/) You may establish an online account with VUE and resister for the exams using the company's web site VUE has more than two thousand testing centers worldwide, making the exams accessible in most areas The exams are presented in English using a PC-based automated examination program Exam questions are presented in multiple-choice single-answer, multiple-choice multiple-answer, and fill-in-the-blank styles However, a majority of the questions on the exams are multiple-choice single-answer Level is aimed at junior to midlevel Linux administrators, who should be comfortable with Linux at the command line as well as capable of performing simple tasks, including system installation and troubleshooting While Exams 101 and 102 are not constructed to be difficult or misleading, together they encompass a wide body of material, making preparation important for success even for experienced administrators Each of the exams covers a series of Topics, which are numbered using a level.topic notation (i.e., 1.2, 2.5, etc.) In the LPI's early stages of development, Topics were assigned to exams based on a different scheme than we see today When the scheme changed, the Topics were redistributed to Exams 101 and 102, but the pairing of Topic numbers to exams was dropped As a result, we have 1.x and 2.x Topics in both Level Exams Each Topic contains a series of Objectives covering specific areas of expertise The Level Topics are distributed between the two exams to create tests of similar length and difficulty without subject matter overlap As a result, there's no requirement for or advantage to taking them in sequence Exam 101 tests five Topics in approximately 60 questions, and Exam 102 tests nine Topics in approximately 72 questions Each exam is limited to 90 minutes file:///C|/Arquivos%20de%20programas/eDonkey2000/in

Audience for This Book The primary audience for this book is, of course, candidates seeking the LPIC Level certification These may range from administrators of other operating systems looking for a Linux certification to complement an MCSE or other certification to Unix administrators wary of a growing pool of Linuxcertified job applicants In any case, this book will help you with the specific information you require to be successful with the Level exams Due to the breadth of knowledge required by the LPI Objectives and the book's 1-to-1 coverage, it also makes an excellent reference for skills and methods required for the day-to-day use of Linux If you have a basic working understanding of Linux administration, the material in this book will help you fill in gaps in your knowledge while at the same time preparing you for the LPI exams, should you choose to take them This book should also prove to be a valuable introduction for new Linux users and administrators looking for a broad, detailed introduction to Linux Part of the LPI exam-creation process includes a survey of Linux professionals in the field The survey results drive much of the content found on the exams Therefore, unlike general-purpose introductory Linux books, all of the information in this book applies directly to running Linux in the real world file:///C|/Arquivos%20de%20programas/eDonkey2000/in

Organization This book is designed to exactly follow the Topics and Objectives established by the LPI for Exams 101 and 102 That means that the presentation doesn't look like any other Linux book you've read Instead, you can directly track the LPI Objectives and easily measure your progress as you prepare The book is presented in two parts Part I covers Exam 101 and Part II covers Exam 102 Each part contains sections dedicated to the LPI Topics, and each of those sections contains information on all of the Objectives set forth for the Topic In addition, each part contains a practice exam (with answers), review questions and exercises, and a handy "highlighter's index" that can help you review important details There is also a glossary at the back of the book, which you can use to help familiarize yourself with different Linux-related terms Parts and 2: LPI Level Exams 101 and 201 Part I and Part II each contain these sections: Exam overview Here you find an introduction to the exam along with details about the format of the questions Study guide This section offers a few tips for preparing for the LPI Level exams and introduces the Objectives contained in the Topic sections that follow Topic sections A separate section covers each of the Topic areas on the exam (five for Exam 101, nine for Exam 102) These sections provide background information and in-depth coverage for each Objective, with On the Exam tips dispersed throughout Review questions and exercises This section reinforces important study areas with review questions The purpose of this section is to provide you with a series of exercises that can be used on a running Linux system to give you valuable hands-on experience before you take the Level exams Practice test The practice test is designed to be similar in format and content to the actual LPI exams You should be able to attain at least an 80 percent score on the sample test before attempting the live exam

forth by the LPI is assigned a numeric weight, which acts as an indicator of the importance of the Objective Weights run between and 10, with higher numbers indicating more importance An Objective carrying a weight of can be considered relatively unimportant and isn't likely to be covered in much depth on the exam Objectives with larger weights are sure to be covered on the exam, so you should
