Introduction

IT Essentials: PC Hardware and Software Labs and Study Guide is a supplemental book that helps the students in the Cisco Networking Academy course prepare to take and pass the CompTIA A+ exams (based on the 2006 objectives). The hands-on labs, worksheets, remote technician exercises, and class discussions from the course are also included within this book to practice performing tasks that will help you become a successful PC technician. By reading and completing this book, you have the opportunity to review all key concepts that the CompTIA exams cover, reinforce those concepts with hands-on exercises, and test that knowledge with review questions.

Who Should Read This Book?

This book is intended for students in the Cisco Networking Academy IT Essentials PC Hardware and Software version 4 course. This student typically is pursing a career in information technology (IT) or wants to have the working knowledge of how a computer works, how to assemble a computer, and how to troubleshoot hardware and software issues.

How This Book Is Organized

This course is divided into two main units. The first unit, covered in Chapters 1 through 10, covers the foundational knowledge that aligns with the CompTIA A+ Essentials exam (220-601). The second unit, covered in Chapters 11 through 16, explores more advanced concepts in greater depth and provides opportunities for practical application to prepare you for the specialized CompTIA A+ technician exams (220-602 for IT Technician, 220-603 for Remote Support Technician, and 220-604 for Bench Technician). You must pass both the A+ Essentials and one of the technician exams to earn the A+ certification.

The Labs and Study Guide is designed as a valuable teaching and learning tool for the Cisco Networking Academy curriculum, incorporating new features to improve your hands-on skills and reinforce the key topics of the course.

Each chapter includes a Study Guide portion and a Lab Exercises portion.

The Study Guide portion of each chapter focuses on certification exam preparation in context with the course objectives and assessments. The Study Guide section is designed to provide additional exercises and activities to reinforce your understanding of the course topics, preparing you for the course assessments and focusing on preparing for the associated certification exams.

The Lab Exercises portion of each chapter features the complete collection of the hands-on labs, worksheets, remote technician exercises, and class discussions specifically written for the IT Essentials course in the Cisco Networking Academy curriculum, reviewed by instructors and formatted and edited by Cisco Press. The labs are designed by Cisco to give students hands-on experience in a particular concept or technology.

Strategies for Exam Preparation

Although many websites offer information about what to study for a particular exam, few sites explain how you should study for an exam. The study process can be broken into various stages. However, key to all these stages is the ability to concentrate. Concentration, or the lack of, plays a big part in the study process.

To be able to concentrate, you must remove all distractions. Although you should plan for study breaks, it is the unplanned breaks caused by distractions that do not allow you to concentrate on what you need to learn. Therefore, first you need to create an environment that's conducive to studying or seek out an existing environment that meets these criteria, such as a library.

Do not study with the TV on, and do not have other people in the room. It is too easy for something on TV to grab your attention and break your concentration. Do not study with others in the room who might not share your dedication to passing this exam. Opinions differ on whether it is better to study with or without music playing. Some people need to have a little white noise in the background to study; if you choose to have music, keep the volume on a low level and listen to music without vocals.

After you find a place to study, you must schedule the time to study. Don't study on an empty stomach. You should also not study on a full stomach; a full stomach tends to make people drowsy. You may also consider having a glass of water nearby to sip. In addition, make sure that you are well rested so that you don't start dozing off. Find a position that is comfortable and use furniture that is also comfortable. Finally, make sure that your study area is well lit. Natural light is best for fighting fatigue.

The first thing that you should do when you begin to study is to clear your mind of distractions. So, take a minute or two, close your eyes, and empty your mind. When you prepare for an exam, the best place to start is to take the list of exam objectives and study the list carefully for its scope. The objectives can be downloaded from the CompTIA website (http://certification.comptia.org/a/). You can then organize your study with these objectives in mind, narrowing down your focus area to specific topics/subtopics. In addition, you need to understand and visualize the process as a whole, to help prepare you to address practical problems in a real environment and to deal with unexpected questions.

In a multiple-choice exam, you have one advantage: The answer or answers are already there, and you just have to choose the correct one(s). Because the answers are there, you can start eliminating the incorrect answers by using your knowledge and some logical thinking. One common mistake is to select the first obvious-looking answer without checking the other options. Don't fall into this trap. Always review all the options, think about them, and then choose the right answer. Of course, with multiple-choice questions, you have to be exact, and you should be able to differentiate among similar answers. This is one reason you need a peaceful place of study without distractions, so that you can read between the lines and don't miss key points.

Taking the Exam

The CompTIA A+ exam is explained in detail, including a list of the objectives, by visiting the following website:

http://certification.comptia.org/a/

When you are ready to take the exam, you must purchase and schedule your two A+ exams. The necessary information to accomplish this can be found at the following website:

http://certification.comptia.org/resources/registration.aspx

Before you take an exam, eat something light, even if you have no appetite. If your stomach is actively upset, try mild foods such as toast or crackers. Plain saltine crackers are great for settling a cranky stomach. Keep your caffeine and nicotine consumption to a minimum; excessive stimulants aren't exactly conducive to reducing stress. Plan to take a bottle of water or some hard candies, such as lozenges or mints, with you to combat dry mouth.

When you take the exam, dress comfortably and arrive at the testing center early. If you have never been to the testing center before, make sure that you know where it is. You might even consider taking a test drive. If you arrive between 15 and 30 minutes early for any certification exam, it gives you the following:

■ Ample time for whatever relaxes you: prayer, meditation, or deep breathing.

■ Time to scan glossary terms and quickly access tables before taking the exam so that you can get the intellectual juices flowing and build a little confidence.

■ Time to visit the washroom before you begin the exam. However, don't arrive too early.

When you are escorted into the testing chamber, you will usually be given two sheets of paper (or laminated paper) with a pen (or wet-erase pen). As soon as you hear the door close behind you, immediately jot down on the paper information that you might need to quickly recall. For example, some of the things that you can jot down are the lengths for the various network cable types or speeds of the various wireless technology. Then, throughout the exam, you can refer to this information and not have to think about it. Instead, you can use this information as a reference and focus on answering the questions. Before you actually start the exam, close your eyes and take a deep breath to clear your mind of distractions. Then, throughout the test, you can jot down little notes that may be used in other questions or do some simple math, such as when you need to figure out how much available memory you have when you have a system that uses part of the memory for video memory.

Typically, the testing room is furnished with anywhere from one to six computers, and each workstation is separated from the others by dividers designed to keep anyone from seeing what's happening on someone else's computer screen. Most testing rooms feature a wall with a large picture window. This layout permits the exam coordinator to monitor the room, to prevent exam takers from talking to one another, and to observe anything out of the ordinary that might go on. The exam coordinator will have preloaded the appropriate CompTIA certification exam, and you are permitted to start as soon as you're seated in front of the computer.

All exams are completely closed book. In fact, you are not permitted to take anything with you into the testing area, but you receive a blank sheet of paper and a pen or, in some cases, an erasable plastic sheet and an erasable pen. Immediately write down on that sheet of paper all the information you've memorized for the test. You are given some time to compose yourself, record this information, and take a sample orientation exam before you begin the real thing. It's a good idea to take the orientation test before taking your first exam; but because all the certification exams are more or less identical in layout, behavior, and controls, you probably don't need to do so more than once.

All CompTIA certification exams allow a certain maximum amount of testing time (90 minutes). This time is indicated on the exam by an onscreen timer clock, so you can check the time remaining whenever you like. All CompTIA certification exams are computer generated, and the questions are multiple-choice questions.
