✦ Exam SK1-001: Server Hardware Specialist

This book is designed to be the only book or course you need to prepare for andpass CompTIA’s Server+ Certification exam The Server+ Certification exam is one

of the newest members of CompTIA’s certification family

This book deals with all of the objectives stated by CompTIA for the Server+ exam.You will learn how to deal with advanced PC hardware issues, such as RAID andSCSI, troubleshooting and problem determination, upgrading, configuration, anddisaster recovery

My hope is that you’ll find this book the most helpful Server+ Certification productreference you’ve ever read, and that you’ll use it not only to prepare for CompTIA’sServer+ Certification exam, but that you’ll come back to it again and again as youperform your day-to-day Server hardware technician tasks

How This Book Is Organized

This book is organized into seven major parts, followed by a robust glossary, anindex, and one compact disc

Here’s what you’ll find in this book:

Part I: Installation

Part I presents the information needed to plan the installation and verify the lation plan, hardware compatibility, power sources, UPS, and network availability.Part I also presents the information about using EDS best practices, rack mounting,installing UPS, verifying SCSI ID configurations and termination, installing externaldevices, and verifying power-on via power-on sequence

Trang 11

instal-x Server+ Certification Bible

Part II: Configuration

Part II covers configuring BIOS/firmware levels, RAID, installing the NOS, externaldevices, installing NOS updates to design specifications and updating manufac-turer-specific drivers Finally, this part also covers the installation of service tools(SNMP, backup software, system monitoring agents, and event logs), performing aserver baseline, and most importantly documenting the configurations

Part III: Upgrading

Part III is all about upgrading the common components within the server This partbegins with performing a full backup and verifying the backup, adding processors,adding hard drives, increasing memory, upgrading BIOS/firmware, upgradingadapters and system monitoring agents This part also explains about upgradingservice tools and UPS

Part IV: Proactive Maintenance

Part IV takes a look at one of the most important parts of being a server hardwaretechnician This part explains how to create a baseline, how to perform regularbackups, monitoring backup performance, and what a system snapshot is Thispart also goes into detail about monitoring agents and physical housekeeping

Part V: Security

Part V addresses different kinds of security issues This part starts off with physicalsecurity issues, such as server room access, types of locks, anti-theft devices,backup tape security such as offsite storage, and fire safe This part also teachesyou about environmental issues, learning how to recognize environmental issues,temperature issues, electrical issues and fire safety

Part VI: Troubleshooting

Part VI is all about troubleshooting server problems In this part you will learn how

to isolate the problem by using your senses, checking hardware, cables, and erals This part also teaches you about software system messages, log files, diskspace, and most important checking for viruses Identifying OS diagnostic tools,selecting the right diagnostic tools, and using vendor resources are also covered.This part ends with information about remote notification for Wake-on-LAN and theright way to document the problem and solution

periph-Part VII: Disaster Recovery

Trang 12

Preface

disasters, human error, vandalism, and sabotage This part will also teach youabout planning for redundancy and how to insure high availability of commonserver components You will also find in this part the different types of backupmedia, which includes digital linear tape (DLT) and CD-R The chapter ends with theimportance of testing the disaster recovery plan regularly

CD-ROM

The compact disc included with this book contains some really excellent resourcesand programs You’ll find a version this book in Adobe PDF format, and a variety ofdifferent programs, From LAN monitoring tools to network analyzers, that I hopeyou will find useful I hope you will enjoy each and every one of these programs Tofind out more about the CD-ROM, please see Appendix D, “What’s on the CD-ROM.”

How Each Chapter Is Structured

When this book was designed, a lot of thought went into its structure, and larly into the specific elements that would provide you with the best possible learn-ing and exam preparation experience

particu-Here are the elements you’ll find in each chapter:

✦ The complete exam objectives that are covered in the chapter

✦ A Chapter Pre-Test to test your knowledge before reading the chapter

✦ Clear, concise text on each topic

✦ Screen shots and graphics that are worth more than a thousand words

✦ A Key Point Summary

✦ A comprehensive Study Guide that contains:

• Exam-style Assessment Questions

• Scenario problems for you to solve, as appropriate

• Answers to Chapter Pre-Test questions, Assessment Questions, andScenarios

How to Use This Book

This book can be used either by individuals working independently or by groups in

a formal classroom setting

For best results, I recommend the following plan of attack as you use this book

First, take the Chapter Pre-Test, then read the chapter and the Key Point Summary

Trang 13

xii Server+ Certification Bible

Use this summary to see if you’ve really got the key concepts under your belt Ifyou don’t, go back and reread the section(s) you’re not clear on Then do all of theAssessment Questions and Scenarios at the end of the chapter Remember, theimportant thing is to master the tasks that are tested by the exams

The chapters of this book have been designed to be studied sequentially In otherwords, it would be best if you complete Chapter 1 before you proceed to Chapter 2

A few chapters could probably stand alone, but all in all, I recommend a sequentialapproach

After you’ve completed your study of the chapters and reviewed the AssessmentQuestions in the book, use the test engine on the compact disc included with thisbook to get some experience answering practice questions The practice questionswill help you assess how much you’ve learned from your study and will also famil-iarize you with the type of exam questions you’ll face when you take the real exam.Once you identify a weak area, you can restudy the corresponding chapters toimprove your knowledge and skills in that area

Prerequisites

Although this book is a comprehensive study and exam preparation guide, it doesnot start at ground zero I assume you have networking knowledge or experienceequal or greater of the scope required to pass an industry networking certificationexam, such as CompTIA’s A+ exam or Network+ exam If you meet this prerequisite,you’re ready to begin this book

If you don’t have the networking knowledge or experience, I recommend you use a

book such as A+ Certification For Dummies (Hungry Minds, Inc.), Network+

Certification For Dummies (Hungry Minds, Inc.) or Networking For Dummies (Hungry

Minds, Inc.) to obtain this knowledge before you begin this book.

Conventions Used in This Book

Every book has its own set of conventions, so I’ll explain the ones I’ve used in thisbook to you right up front

Icons

You’ll see several icons throughout each chapter There are five different types oficons used in this book Below are the explanations of each icon:

Trang 14

Preface

This icon is used to warn you that something unfortunate could happen if you’renot careful It also points out information that could save you a lot of grief It’soften easier to prevent a tragedy than to fix it afterwards

This icon points you to another place in this book for more coverage of a lar topic It may point you back to a previous chapter where important material hasalready been covered, or it may point you ahead to let you know that a topic will

particu-be covered in more detail later on

This icon points out important information or advice for those preparing to takethe Server+ certification exam

Sometimes things work differently in the real world than books — or product umentation — say they do This icon draws your attention to the author’s real-world experiences, which will hopefully help you on the job if not on the Server+
