A+ Exam Cram 6th edition, 1st printing

Updated 2/15/2014 - (Some E-books may already include these changes.)

(Errors are in red. Modifications are in blue. Additions are not color-coded. Page numbers refer to the print book. for e-books, refer to the Chapter and Section.)

Error: Ch 4, Page 91, Figure 4.4 caption: PC3-12800 is not correct. The caption should read "A 240-pin PC3-10600 4 GB DIMM (DDR3-1333)"

Addition: Ch 6, Page 149, Table 6.2, Note: Older, deprecated SCSI connections use 50 pins. An example of a 50-pin SCSI connection is Ultra2 SCSI (Fast-40) which can transmit 40 MB/s. It only allows for a maximum of 8 devices.

Typo: Ch 6, Page 160, Answer to Question 13: The second sentence should be disregarded. "The best answers are tape drives and hard drives." was from another question's explanation.

Modification: Ch 7, Section: Pointing Devices, page 187, 2nd paragraph: Now and again you will encounter users reporting that when they type on the keyboard, the mouse pointer scrolls across the screen. This is sometimes referred to as a ‘ghost cursor’. It could be because the user’s sleeve is brushing up against the touchpad. To remedy this, pointing devices can be turned off within Windows, usually through the laptop manufacturer’s software. Watch out for situations in which the entire device was disabled or perhaps just the pad portion of the touch pad was disabled. It’s also possible to disable tapping ability of the touch pad, while still allowing movement of the cursor. In rarer cases, a ghost cursor occurring while working in the operating system or in a word processor can be caused by a bad driver or the OS itself. If this happens, reinstall or update the mouse/touchpad driver, the video driver, and update the OS as well.

Modification: Ch 7, Page 201, Question 4: This question is outdated and should be disregarded. If CompTIA asks about expanding a desktop over two monitors, it should be referred to as "multiple monitor", "multiple displays", or "extend these displays". (This is question ID COMPTIA-APAEC-220-801-07-CQ-004 in the practice test engine.)

Clarification: Ch 8, Table 8.5, 6th row: setupapi*.log can refer to multiple files (the asterisk is wild) including setupapi.offline.log (as on a Win7 computer), and Online configuration phase files: and This applies to any other references in the book to setupapi*.log. See the following links for more information on Windows setup log files:

Modification: Ch 8, Section: Windows 7 Installation Methods, page 217, 1st Note: The Windows System Image Manager (SIM) for Win7 is part of the Windows Automated Installation Kit (AIK), which can be downloaded from; just search for Windows Automated Installation Kit (AIK). For detailed instructions on how to use SIM, see the following link:

The Windows Preinstallation Environment, known as Windows PE, or simply WinPE is also available as part of the Windows AIK. It can be booted from optical disc, USB flash drive, over the network via PXE or from the hard drive. Windows 7 uses WinPE version 3.0 and 3.1. It can be used to run recovery tools such as the Windows Recovery Environment (WinRE), and Winternals and for running disk cloning utilities.

For general information about Windows 7 deployment, see the following link:

Modification: Ch 9, Topics box on page 241: This chapter also covers 220-801 objective 1.5. There is a little bit of content on RAID that applies to that objective. Remember though that you might see RAID questions on the 220-801 or 220-802 exams.

Error: Ch 9, Page 264, Msconfig section, 4th sentence: "Msconfig also lets you select from different boot options and can start or stop services." should read: "Msconfig also lets you select different boot options and can enable/disable services."

Modification: Ch 9, Section: Windows Registry, page 274, 1st paragraph: ….Later, individual keys or the entire registry can be imported with the Import option on the File menu, in case a modification was not successful. For example, certain changes to the registry could cause the graphical interface (GUI) to fail to load. Or audio could become disabled. Again, be sure to make a backup before playing around with the registry. To repair a missing graphical interface or audio issue that is registry-related, attempt a System Repair from the Windows DVD, or if possible restore an older version of a backed up registry. (More about System Repair in Chapter 11 “Troubleshooting Windows.”)

Error: Ch 9, Page 282, Answer to Question 5: The answers should be B, C, and D: Task Manager, Computer Management, and the Command Prompt. Msconfig is not a correct answer as it lets you enable/disable services, but not start/stop them. (In the practice test engine this is question ID COMPTIA-APAEC-220-802-09-CQ-011.)

Error: Ch 9, Page 298, Question 5: The answer to this question should be Winload.exe, not Bootmgr. replace Bootmgr with Winload.exe as answer B and in the explanation.

Error: Ch 10, Page 304, Question 3: "All Programs" is missing from the answer. The correct answer should then be Click Start > All Programs > Windows Update; then click the Change settings link. (Test Engine ID: COMPTIA-APAEC-220-802-10-CQ-003)

Addition: Ch 10, Page 315, 2nd Cram Quiz, Question 4: The explanation should read as "Windows 7/Vista", not just "Windows Vista".

Error: Ch 10, Page 315, 2nd Cram Quiz, Question 8: Answer C is not correct. The answer should be A - File Sectors are made contiguous. However, the subsequent explanation is correct.

Addition: Ch 11, Page 326, Windows XP Boot Errors section, 4th bullet point: It should be noted that commands such as fixboot and fixmbr can be used in the Windows XP Recovery Console to fix issues such as "NTLDR is Missing" or other issues where a virus has infected the Master Boot Record.

Error: Ch 11, Page 352, 3rd Cram Quiz, Question 1: Answers A and C would both be correct here. The difference is that answer A (Chkdsk) can recover some lost files (such as orphaned .tmp files) but answer C (Chkdsk /R) can recover lost files, and fix errors on the disk. This is question ID COMPTIA-APAEC-220-801-12-CQ-011 in the test engine.

Addition: Ch 12, Page 358, Table 12.2, last row: A composite video RCA connection (yellow plug) sends an analog video signal; it is sometimes used by older gaming systems and other electronic devices, possibly in combination with stereo RCA audio connections (red and white plugs.)

Error: Ch 12, Page 385, Question 1: The answer "RCA" is also correct. Today's soundcards can also have RCA input/output connectors.

Clarification: Ch 14, Page 409, Laser printing process: There is a bit of confusion concerning the laser printing process. I did not list the laser printing process in the same sequence as CompTIA objective 220-801, 4.1. The deviation is the Cleaning stage. As I mention in the book, the cleaning stage can occur at the beginning or the end of the process, but CompTIA lists it at the end. However, this will depend on the manufacturer, the printer, and the age of the printer. Take for example the following link from HP support - Link. This shows the cleaning stage as first. In fact, the CompTIA exams had this listed as first for many years. However, for the 800 series exams, the CompTIA objectives say the following:

" - Imaging process: processing, charging, exposing, developing, transferring, fusing and cleaning"

So, we have to assume that this is a sequential list, and if you are asked on the A+ exams when the cleaning stage happens, your answer should be "after the fusing stage". However, the sequence is not nearly as important as is the troubleshooting that is involved with each individual stage. For example, if a laser printer is producing completely blank sheets, the stage you should investigate first would be the Developing stage - there could be a problem with how the toner is applied to the drum, often fixed by replacing the toner cartridge. Afterward, you would check the Transfer stage in case there is a voltage issue with the corona wire. Those are the types of questions you should expect on the CompTIA A+ exams, so be sure to understand how to troubleshoot laser printing issues.

For those of you that have taken the A+ exams previously, objective 4.1 deviates from what you might have previously learned (where the process was Cleaning, Conditioning, Writing, Developing, Transferring, and Fusing). As I mention in the book, CompTIA inlcudes a "processing" stage which happens prior to other steps. This is where document processing occurs at the printer (for example raster image processing) and at the print server or other computer that controls the printer. In addition, as mentioned the cleaning stage is shown at the end as opposed to the beginning. Keep these changes in mind when you take the exams.

Addition: Ch 14, Page 428, Question 8 Explanation: In addition to the explanation listed, it is also possible for the toner cartridge to fail, causing blank pages to print. This would mean that blank pages could be caused by failures during the Developing and the Transferring stages of the laser printing process, with failures during the Developing stage being more common.

Error: Ch 15, Page 468, Table 15.8, 3rd row: For 802.11g the Indoor range says 35 m/115 ft. This should be 38 m/125 ft. However, keep in mind that these ranges are all approximate, and will vary depending on several factors.

Addition: Ch 16, Section: Preventing and Troubleshooting Spyware, page 503, add to end of 2nd bullet: Another attack similar to session hijacking is browser redirection. This is when a user’s web browser is automatically redirected to one or more malicious websites. It can be done when a user inadvertently accesses a malicious website from a search, can be caused by a Trojan that modifies a computer’s DNS entries (ex. DNSChanger), or can be caused by spyware or a virus that configures a proxy server address within the browser and/or modifies the HOSTS.txt file. This can be avoided by increasing a browser’s security settings, updating antivirus programs, and through user education. It can be fixed by scanning the system with antivirus software, removing the proxy server address from the browser’s settings, and deleting and re-writing the HOSTS.txt file. More information about proxy server addresses is available in Chapter 15, “Networking.” More information about browser and session hijacking can be found in Chapter 16, “Security.”

Modification: Ch 19, Section: Getting Ready and the Exam Preparation Checklist, page 602, 4th paragraph: As of 10/9/2012 the 800 series A+ exams are a maximum of 90 questions each. Not 100 as it says in the text. Also, be prepared for a couple of "performance-based" questions which are more hands-on questions that run in a simulator. You will probably see a couple of these in the beginning of the exam.

Error: 220-801 Practice Exam, Page 619, Question 44: The question should ask about a resolution of 1680 x 1050, not 1600 x 1050. The answer of WSXGA+ is still correct on page 638, but the explanation should say 1680 x 1050 instead of 1600 x 1050.

Error: 220-801 Practice Exam, Page 621, Question 55: Answers B should say converts DC to AC, not AC to DC. An inverter can be found in devices such as a laptop display, special types of gasoline-based generators (also known as inverters), and in switched-mode power supplies (SMPS) in PCs (though it is a minor function).

Error: 220-801 Practice Exam, Page 633, Question 11: Answers A and B are both correct. This is because 802.11a and 802.11b are very similar when it comes to indoor range. 802.11g is not far behind. For the exam, remember that 802.11n has close to double the range of 802.11a, b, and g.

Modification: 220-801 Bonus Practice Exam, Question 11: In the explanation, the first sentence should read: "An integrated GPU means that it is integrated to the main CPU or the motherboard of the computer." This is question ID COMPTIA-APAEC-220-801-BQ-011 in the test engine.

Modification: 220-802 Bonus Practice Exam, Question 15: The correct answer is "Drill". However, the question has become a bit outdated. There are indeed hard drive "shredders" as well, so this would be a correct answer also. This is question ID COMPTIA-APAEC-220-802-BQ-015 in the test engine.


CompTIA objectives errata:

Older versions of the CompTIA A+ 220-801 objectives display "Toner probe" within objective 2.10. This should be "tone and probe". They are networking tools used to locate an individual cable. A tone generator creates the tone on a cable, while an inductive amplifier is used to "probe" for that wire in a different location of the network, thus finding the tone, and locating the cable in question..

Older versions of the CompTIA A+ 220-802 objectives have a few issues:

- tlist should be tasklist. tlist is an older Windows command, not used in Win 7/Vista/XP

- kill should be taskkill. kill is an older Windows command, not used in Win 7/Vista/XP

- regsrv32 should be regsvr32. note the letters r and v are switched.

Last I checked on 8/3/2012 CompTIA fixed the tasklist and taskkill issues, but has not fixed the regsrv32 typo.

Make sure you download the latest version of the objectives for both 220-801 and 220-802!!
