Introduction The CompTIA A+ is one of the most popular IT certifications in the industry, and I think it's also one of the most enjoyable study experiences. Whether you're just getting started in information technology or you're a seasoned veteran, you have to appreciate the vast array of hardware and software that's covered in the A+ exams. If you love technology, then the A+ certification is for you. I've created these sample exams to help you learn what you'll need to pass the exam, but I also hope they provide some additional context and knowledge that you can use once the certification process is over. In information technology, the learning process never ends. I wish you the best success on your journey! - Professor Messer The CompTIA A+ Core 2 Certification The 220-1102 A+ Core 2 certification covers many different topics, and includes everything from IT security to software troubleshooting. Here's the breakdown of each domain and the percentage of each topic on the 220-1102 A+ exam: Domain 1.0 - Operating Systems- 31% Domain 2.0 - Security - 25% Domain 3.0 - Software Troubleshooting - 22% Domain 4.0 - Operational Procedures- 22% The practice exams in this book follow this breakdown, so you should find that the distribution of questions on a practice exam will be very similar to what you'll see on the actual exam. i How to Use This Book This book contains three separate 90-question practice exams; Exam A, Exam B, and Exam C. The exams are designed to emulate the format and complexity of the actual Core 2 A+ exam. Take one exam at a time. The difficulty levels are similar between exams, so it doesn't matter which exam you take first. The 220-1102 A+ exam is 90 minutes in length, so try setting a timer when you start your practice exam. Time management is an important part of the exam. The first section of each practice exam is the list of questions. There's a link next to every question ("Quick Answer" or "The Details") that will jump immediately to the quick answer page or the detailed answer page. If you're using the digital version, your PDF reader keys can quickly jump back to the question page. Adobe Reader in Windows uses Alt-Left arrow and macOS Preview uses Command-[ to move back to the previous view. Be sure to check your PDF reader for specific navigation options. The quick answer page is a consolidated list of the answers without any detail or explanation. If you want to quickly check your answer sheet, this is the page for you. A detailed answer is available for each exam question. This section repeats the question, the possible answers, and shows the answer with a detailed explanation. This section is formatted to show only one answer per page to avoid giving away the answer to any other questions. Digital readers can use your PDF reader's back button to quickly jump back to the questions. As you go through the exam, write down the answers on a separate sheet of paper. You can check the answers after the 90 minutes have elapsed. You can grade your results against the quick answer page. For incorrect responses, be sure to check the detailed answer pages for information on why certain answers were considered correct or incorrect. After each detailed answer, a video link is available for more information on the topic. You can click the link in your PDF or use your camera to view the QR (Quick Response) code on the page. Your camera app will provide a notification message that will launch the video page in your browser. The URL is also provided for manual entry. ii You have the option of using each practice test as a 90 minute timed exam, or as a casual Q&A. Try stepping through each question, picking an answer, and then jumping to the detailed explanation to learn more about each possible answer. Here's a scoring chart: Less than 63 questions correct / 70% and lower - Use the exam objectives at the end of each detailed answer to determine where you might need some additional help. 63 to 72 questions correct / 70% to 80% - You're so close! Keep working on the areas you're missing and fill in those gaps. 73 to 81 questions correct / 80% to 90% - This is a strong showing, but some additional studying will help you earn points on the real exam. Although the actual 220-1102 A+ exam does not calculate the final score as a percentage, getting an 85% on the practice exam can be roughly considered a passing grade. More than 81 questions correct / over 90% - You're ready for the real thing! Book your exam and pass your 220-1102 A+ exam! The detailed answer pages break down every correct answer and every incorrect answer. Although it's useful to know when you got a question right, it's more important if you understand exactly why a question was marked wrong. If you understand all of the technologies on these sample exams, then you'll be ready for the real thing. iii Practice Exam A Performance-Based Questions A1.

An office power system occasionally experiences minor voltage spikes during the business day. Which of the following would be the BEST way to address this power issue? ❍ A. Power down when not actively working ❍ B. Confirm that the building has an electrical ground ❍ C. Connect a surge suppressor to each system ❍ D. Maintain an inventory of replacement power supplies The Answer: C. Connect a surge suppressor to each system A surge suppressor can help to even out voltage spikes in an electrical system. It's common to use a surge suppressor at each workstation to limit the effect of these voltage spikes. The incorrect answers: A. Power down when not actively working Although powering down a system would certainly protect it from voltage issues, it would not be a very efficient way of working. B. Confirm that the building has an electrical ground A good ground is an important part of any building's electrical system, but the ground won't help filter out the occasional voltage spike. D. Maintain an inventory of replacement power supplies If you don't use surge suppressors and you have constant power spikes, you might need replacement power supplies. However, it would be more effective to use surge suppressors instead of replacing power supplies.

A system administrator is upgrading an email service in the corporate data center. During the upgrade, an error message appears and the upgrade fails. Subsequent attempts to perform the upgrade also fail. Which of the following processes should the system administrator follow to return the email server to its previous state? ❍ A. Rollback plan ❍ B. Disaster recovery plan ❍ C. Incident response plan ❍ D. Power plan The Answer: A. Rollback plan Even with the best planning, there can always be unexpected events. Every planned change needs to have a rollback plan to return the environment to its original state. The incorrect answers: B. Disaster recovery plan A disaster recovery plan is written for major events that impact a large portion of an organization. An email upgrade that goes badly does not meet the scope of needing a disaster recovery plan. C. Incident response plan An incident response plan is commonly used to address a security event. Issues discovered during the planned upgrade of an email server would not be associated with an incident response plan. D. Power plan The Windows operating system allows users to modify the power use on their systems using built in power plans. These environmental controls are not associated with the change control process.

Use System Restore to rollback to a previous configuration The Answer: C. Move the webcam to a different USB interface The resources associated with a USB (Universal Serial Bus) interface can vary based on the interface type and USB controller version. If these resources are exceeded on a USB controller, the system will display a message explaining the lack of resources. The incorrect answers: A. Close all large-memory processes The resources associated with the USB interface are not related to the available RAM in the operating system. B. Modify the BCD The Windows BCD (Boot Configuration Data) is used during startup to identify the location of the Windows installation. Updating the BCD will not resolve USB-related resource contention. D. Use System Restore to rollback to a previous configuration This issue is related to the hardware connected to a USB controller. Changing the configuration of the operating system will not resolve this issue.
