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+ Certification The 220-1101 A+ Core 1 certification covers many different topics, and includes everything from hardware troubleshooting to cloud technologies. Here's the breakdown of each domain and the percentage of each topic on the 220-1101 A+ exam: Domain 1.0 - Mobile Devices - 15% Domain 2.0 - Networking - 20% Domain 3.0 - Hardware - 25% Domain 4.0 - Virtualization and Cloud Computing - 11% Domain 5.0 - Hardware and Network Troubleshooting - 29% The practice exams in this book follow this breakdown, so you should find the distribution of questions on these practice exams to be very similar to what you'll find during your 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 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 220-1101 A+ exam is 90 minutes in length, so you may want to set 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. After reading the detailed answer, you can use the PDF reader's "back" button to quickly jump back to the questions. As you step through the exam, write down the answers in a separate window or use your PDF reader's annotation features to mark the answer. You can check the answers after the 90 minutes have elapsed. You can grade your results against the quick answer page. You might also want 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 smartphone camera app 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 220-1101 A+ exam does not calculate the final score as a percentage, getting an 85% on the practice exam can be considered a passing grade. More than 81 questions correct / over 90% You're ready for the real thing! Book your exam and pass your 220-1101 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.

The printer in the accounting department has stopped all printing processes. The print queue shows seven jobs in the queue waiting to be printed. Which of the following would be the BEST next troubleshooting step? ❍ A. Send a test job to the printer and move it to the top of the queue ❍ B. Restart the printer's spooler ❍ C. Install an updated version of the printer driver ❍ D. Delete everything in the queue and resend the print jobs The Answer: B. Restart the printer's spooler The print spooler is the software responsible for storing print jobs and sending them to the printer. If the printer spooler has failed or has stopped, then none of the print jobs will be sent to the printer. The incorrect answers: A. Send a test job to the printer and move it to the top of the queue Since the print spooler is the issue, it won't matter where a print job might be in the queue. A test print job will sit at the top of the queue just like any other print job. C. Install an updated version of the printer driver The printer driver on a client workstation is responsible for formatting the print job in a way the printer can properly interpret during the printing process. Changing the print driver won't fix problems with the print spooler. D. Delete everything in the queue and resend the print jobs If the spooler is having problems, then deleting the print jobs will only require users to resend the print requests, which will then sit in the queue and not print.

A system administrator has connected an external USB drive to a computer to transfer some documents. When booting the computer, the system tries to boot from the external drive and gives an error message. Which of the following would be the BEST way to prevent the USB drive from booting? ❍ A. Modify the BIOS to boot from the internal hard drive ❍ B. Modify the boot order in Windows Disk Management ❍ C. Rebuild the MBR on the external hard drive ❍ D. Disable the external drive in Device Manager The Answer: A. Modify the BIOS to boot from the internal hard drive The boot order is managed in the system BIOS, and one way to avoid the computer from attempting to boot from an external storage device is to move the internal drive to have a higher boot priority. The incorrect answers: B. Modify the boot order in Windows Disk Management Windows Disk Management is not used to configure the boot order of the computer. By the time Windows has loaded, the boot order has already been determined. The boot order is configured in the system BIOS. C. Rebuild the MBR on the external hard drive Rebuilding the MBR (Master Boot Record) of the external hard drive will not prevent the computer from attempting to boot to the drive. Rebuilding the MBR would only be necessary if the boot record was erased or damaged. D. Disable the external drive in Device Manager Since Windows Device Manager is only active after the system boots, disabling the external drive would not prevent the boot process. Disabling the drive in Device Manager would only prevent Windows from accessing the drive once the system was booted.

A user's print jobs to a new multifunction printer produce pages of garbled text, but jobs from other users are printing normally. Which of the following would be the MOST likely reason for this issue? ❍ A. Printer driver specifies secured prints ❍ B. Faulty network cable ❍ C. Print driver is configured for PCL ❍ D. Application is not authorized to print The Answer: C. Print driver is configured for PCL The page description language configured in a printer driver must match the language on the printer. If a device prints to a PostScript printer using Hewlett-Packard's PCL (Printer Command Language), the output will appear garbled and unreadable. The incorrect answers: A. Printer driver specifies secured prints Secured printing allows the user to associated their print job with a PIN (Personal Identification Number), and the job will not print until the PIN is entered at the printer console. This process does not cause the output to appear garbled or corrupted. B. Faulty network cable A faulty cable would cause the printer to receive data slowly or not at all. The output of the printer would not be affected by a faulty Ethernet cable. D. Application is not authorized to print A print authorization is commonly determined by the user's rights and permissions and is not based on the application. If a user did not have rights to print, then no print job would be queued and no output would be created.

A network connection in a conference room was installed years ago, and there’s no documentation for the cable run. Connecting a device to the cable results in a successful Ethernet connection, so the other end of the cable should terminate somewhere in the wiring closet. Which of these tools would be the best choice to find the other end of the network connection? ❍ A. Cable tester ❍ B. Tone generator ❍ C. Multimeter ❍ D. Crimper The Answer: B. Tone generator A tone generator is used to produce an analog tone on the cable, and an inductive probe is used to "listen" for the tone on the other end of the cable. The incorrect answers: A. Cable tester A cable tester could be used to confirm the wire map of the cable, but you would first need to locate both ends before that would be possible. A cable tester doesn't provide a way to locate both ends of a cable. C. Multimeter A multimeter could be used to verify continuity and the wire map of the cable, but both ends of the cable would need to be close to the multimeter. A multimeter can't be used to locate both ends of a cable. D. Crimper If the RJ45 connector on the cable was faulty, a crimper could be used to attach a new connector to the cable.

A network administrator has received a ticket complaining of port flapping on an Ethernet switch. Which of the following would be the MOST likely reason for this issue? ❍ A. Firewall rule is blocking traffic ❍ B. Faulty crimp on an Ethernet connector ❍ C. Excessive jitter measurements ❍ D. Duplex mismatch The Answer: B. Faulty crimp on an Ethernet connector Port flapping describes a network interface that constantly transitions between connected and disconnected. This can sometimes be related to software or firmware, but is most likely associated with a hardware issue. For example, a faulty cable or connector could cause intermittent connectivity and create a flapping Ethernet port. The incorrect answers: A. Firewall rule is blocking traffic Denying or allowing traffic on a firewall would not cause an Ethernet interface to physically disconnect or connect itself from the network. C. Excessive jitter measurements Jitter measures the time between network frames, and excessive jitter could disrupt real-time voice or video communication. However, excessive jitter would not cause an Ethernet interface to physically disconnect or connect. D. Duplex mismatch A duplex mismatch would certainly cause performance issues and slowdowns, but it would not cause an Ethernet link to constantly disconnect and reconnect.

A user has powered on their computer and received the message “Operating system not found.” A check of the system shows that the SATA drive cables are properly connected. Which of the following would be the NEXT best troubleshooting step? ❍ A. Boot to Safe Mode ❍ B. Replace the boot drive ❍ C. Restore from a known good backup ❍ D. Check for removable drives The Answer: D. Check for removable drives If a USB (Universal Serial Bus) storage device is connected to a computer and the BIOS (Basic Input/Output System) is checking USB devices before the primary storage drive, the "Operating system not found" error could appear with some USB devices. To avoid this error, the boot order in the BIOS can be changed, or the USB device can be disconnected during the boot process and reconnected after the operating system has started. The incorrect answers: A. Boot to Safe Mode Safe Mode is a Windows mode used to launch the operating system with minimal services and OS requirements. Safe Mode requires a bootable drive, so the error message in this question would prevent Safe Mode from starting. B. Replace the boot drive There's not enough information to determine if the boot drive is bad or faulty, so immediately replacing it would be premature. If there aren't any removable storage devices connected to the system, then running hardware diagnostics of the drive would be a good next step before considering a hardware replacement. C. Restore from a known good backup This question doesn't provide enough information about the state of the primary boot drive, so making any significant changes to the data on the drive would not be the best next step.

A user is having an issue with a smartphone battery bulging and physically pushing the screen away from the phone. The rest of the phone appears to be operating normally. Which of the following should be the BEST next troubleshooting step? ❍ A. Power off the phone and contact support ❍ B. Upgrade to the latest OS version ❍ C. Replace the screen ❍ D. Perform a factory reset The Answer: A. Power off the phone and contact support A swollen battery indicates damage to the battery and could potentially be a fire hazard. The phone should be powered down and the damaged battery should be removed by a trained smartphone support technician. The incorrect answers: B. Upgrade to the latest OS version Upgrading software on the smartphone will not fix a damaged battery. The best practice with a bulging or swollen battery is to power down the device and replace the battery. C. Replace the screen Although a bulging battery may damage other components, there's nothing in this question that indicates any damage to the screen. Any necessary repairs should take place after the damaged battery is replaced. D. Perform a factory reset A factory reset is a good option for troubleshooting unknown software issues, but it won't correct the damage to a battery. The smartphone should be powered off immediately and repaired.

A client’s laptop appears to boot normally, but nothing ever appears on the LCD. After closer inspection, you notice the output is visible but it's too faint to clearly see anything. What is the MOST likely cause of this issue? ❍ A. Video card ❍ B. Inverter ❍ C. Video driver ❍ D. Power adapter The Answer: B. Inverter The inverter powers the CCFL (Cold Cathode Fluorescent Lamp) LCD (Liquid Crystal Display) backlight, allowing you to easily view the pixels on the display. Most newer laptops will use LED (Light Emitting Diode) backlights with existing DC (Direct Current) power and these LED lights don’t require an inverter. The incorrect answers: A. Video card A faulty video card might cause the video display to stop working completely, or the information on the screen may be corrupted. A faulty video adapter does not commonly cause the display to have a decreased backlight setting. C. Video driver Bad video drivers often cause issues with resolution settings or aspect ratios, but a bad video driver does not commonly affect the backlight settings. D. Power adapter A bad power adapter would cause a laptop to fail during the boot process or fail to properly charge a battery. A bad power supply would not usually cause everything to work properly except for the backlight.

A graphics designer is experiencing increasing delays when accessing files on her hard drive. The user maintains a daily backup of all data on the drive. Which of these would be the BEST next troubleshooting step for this issue? ❍ A. Reinstall Windows ❍ B. Perform a hard drive diagnostic ❍ C. Restore from the daily backup ❍ D. Boot to Safe Mode The Answer: B. Perform a hard drive diagnostic Before making any changes, it would be useful to gather more information about this problem. A hardware diagnostic would determine if the hard drive itself is working properly. If the hard drive is operating normally, the troubleshooting process can then shift to the operating system and software. The incorrect answers: A. Reinstall Windows Reinstalling Windows won't help if the hard drive is not operating properly. The installation process is also a time-consuming and significant change, so it's important to know if the underlying hardware is working. C. Restore from the daily backup The root cause of this issue hasn't been identified, so any significant change to the user's data would be premature. The user may have also modified some of this data since the backup was taken, so restoring the backup could potentially result in the loss of user data. D. Boot to Safe Mode Safe Mode will start Windows with a minimal configuration, and this could help troubleshoot software issues with the operating system itself. Before analyzing the software, it would be important to know if the underlying hardware is working properly.

Which of the following would be MOST likely found on an optical disc? ❍ A. Document archive ❍ B. Operating system boot files ❍ C. RAID parity files ❍ D. BIOS configurations The Answer: A. Document archive An optical disc such as a DVD-ROM (Digital Versatile Disc - Read Only Memory) has the advantage of a relatively large storage area and the ability to write once and never worry about an accidental deletion. The storage of documents and other files is a common use of optical discs. The incorrect answers: B. Operating system boot files Although it is possible to boot an operating system from an optical disc, it's not a common use of the format. It's much more common to store operating system files on a local storage drive with a higher storage capacity and throughput, such as a hard drive or SSD (Solid-State Drive). C. RAID parity files A RAID (Redundant Array of Independent Disks) array requires that all of the data and parity information reside on the local storage drives. Parity information would not be stored on an optical disc. D. BIOS configurations BIOS configurations need to be accessible from the motherboard of a computer, and not from other storage devices.

A technician is connecting a laptop to an LCD projector in a conference room. The display on the laptop works properly, but the projector image is constantly flickering and pixelating. The technician has modified the resolution and refresh rates, but the projector image continues to flicker. Which of the following would be the BEST next troubleshooting step? ❍ A. Replace the video cable ❍ B. Disable the laptop display ❍ C. Replace the projector bulb ❍ D. Power cycle the projector The Answer: A. Replace the video cable A display issue associated with flickering and poor video quality would commonly point to the connection between the video adapter and the display device. In the case of an LCD (Liquid Crystal Display) projector, there's sometimes a very long (and very worn) cable that can cause signal issues to show on the projected image. The incorrect answers: B. Disable the laptop display Disabling the laptop display won't help with any signal problems. This would probably also hinder the troubleshooting process because you wouldn't be able to properly see the display information due to all of the flickering and pixelating. C. Replace the projector bulb The bulb in an LCD projector either works or doesn't, so it will be very obvious if the bulb is faulty. In this example, the projector bulb is working, but the information displayed on the projector is difficult to see. D. Power cycle the projector The projector itself would not commonly cause any display flickering or image problems, so power cycling the projector wouldn't normally resolve this type of problem. If all other troubleshooting tasks fail, then power cycling everything might be an option, but it wouldn't be the first troubleshooting step.

The stylus on a Windows tablet will no longer interact with the user interface. Which of these would be the MOST likely cause of this issue? ❍ A. Digitizer ❍ B. Backlight ❍ C. Contrast ❍ D. Inverter The Answer: A. Digitizer The digitizer is the component in a touch screen to convert analog input from a fingerprint or stylus into a digital input. If the digitizer is having an issue, then problems will occur with any direct screen input. The incorrect answers: B. Backlight An LCD (Liquid Crystal Display) screen does not produce any light, so a backlight is used to make the screen bright enough to see. The brightness of the screen does not have any effect on the stylus. C. Contrast The contrast and brightness controls do not effect the use of a stylus on an LCD. D. Inverter An inverter is used in older LCDs to invert DC (Direct Current) power into AC (Alternating Current) power. This AC power is used by CCFL (Cold Cathode Fluorescent Lamp) backlights. Most of the newer LCDs contain LED (Light Emitting Diode) backlights which use the existing DC power and do not require an inverter.

A user in the accounting department needs to print a form on the laser printer on both sides of the page. Which of the following options should be configured in the accounting software? ❍ A. Collate ❍ B. Orientation ❍ C. Duplex ❍ D. Resolution The Answer: C. Duplex The duplex setting prints the output on both sides of the page, and a printer that supports duplexing will flip the page over without any manual intervention from the user. The incorrect answers: A. Collate When printing multiple copies, the collate option will print all of the pages in a document before printing the next copy. B. Orientation The orientation setting will change the output between portrait or landscape. The orientation option will not change which sides of the page are used during the printing process. D. Resolution The resolution setting will modify the number of dots per inch used for the output. A larger number of dots per inch will increase the resolution and make the text and images appear sharper on the page.

A user needs to connect their laptop to the wired Ethernet network, but the laptop does not have an integrated Ethernet interface. Which of the following would allow the laptop to connect to an Ethernet network? (Pick TWO) ❍ A. Docking station ❍ B. VGA interface ❍ C. USB to Ethernet adapter ❍ D. DisplayPort to HDMI cable ❍ E. DVI to HDMI adapter ❍ F. Bluetooth The Answer: A. Docking station C. USB to Ethernet adapter There are a few options for creating a wired Ethernet connection on a laptop computer. Using a docking station is a common solution to provide many different interfaces, and docking stations often include the option to install a full-size PCI Express (Peripheral Component Interconnect Express) adapter. A USB (Universal Serial Bus) to Ethernet adapter is a simpler solution that only provides an Ethernet interface, but it's much more portable than a docking station. The incorrect answers: B. VGA interface A VGA (Video Graphics Array) interface is an interface for video output and does not provide Ethernet connectivity. D. DisplayPort to HDMI cable Both DisplayPort and HDMI (High-Definition Multimedia Interface) provide video output and are not used for Ethernet on a laptop computer. E. DVI to HDMI adapter DVI (Digital Visual Interface) and HDMI are video interfaces and do not provide a wired Ethernet link. F. Bluetooth Bluetooth is a wireless PAN (Personal Area Network), and it does not provide wired Ethernet connectivity.

A server administrator has received an alert showing one drive in a RAID 1 array has failed. Which of the following would be the best way to resolve this alert? ❍ A. Replace the bad drive and resync the array ❍ B. Replace all drives in the array and resync the array ❍ C. Replace the bad drive and restore from backup ❍ D. Convert the array to RAID 0 and replace the drive ❍ E. Replace all drives in the array and restore from backup The Answer: A. Replace the bad drive and resync the array A RAID 1 (Redundant Array of Independent Disks, level 1) array is a mirrored array, which means all of the information on one physical drive is also copied and maintained on a separate drive. If one drive fails, the drive with the redundant data continues to be available. To repair the array, the bad drive needs to be replaced and the data from the redundant drive is synchronized to the new drive. The incorrect answers: B. Replace all drives in the array and resync the array A RAID 1 array continues to run after a drive outage, and all data continues to be available. There's no reason to replace all of the drives in the array, and if all drives were replaced there would be nothing to resync. C. Replace the bad drive and restore from backup Since no data is lost after a single drive failure in a RAID 1 array, restoring from backup is not necessary. D. Convert the array to RAID 0 and replace the drive RAID 0 is striping data across drives, and there is no redundancy in a RAID 0 array. It's unusual to convert arrays between RAID levels, and a conversion is not necessary to restore full functionality to this RAID 1 array. E. Replace all drives in the array and restore from backup There's no need to restore from backup when replacing a single drive in a RAID 1 array.
