Trouble Spots

Many examinees find the following topics to be more difficult portions of the exam:

  • CPU architecture: Topics such as CPU speeds and types of processors can be difficult to remember accurately for some examinees. Be sure to take notes on these topics and quiz yourself often to help memorize them.
  • Windows troubleshooting: The exams will question an examinee on how to troubleshoot Windows—especially the second exam. Due to the sheer volume of troubleshooting scenarios, it is recommended that the examinee install operating systems on a separate computer (or within a virtual machine), and practice breaking and fixing.
  • Printer troubleshooting: There are several types of printers, and many things that can go wrong with each. An examinee should study the CompTIA 6-step troubleshooting process, and really spend a lot of time memorizing the various reasons a printer could fail (especially laser printers) and how to fix those issues.
  • Security: The 220-800 series exams have an increased amount of security. Examinees should spend time researching how to secure their individual computer and wireless router.
  • Mobile Devices: The 220-800 series exams have a new “Mobile Devices” domain that focuses on Android and iOS. Examinees should try to practice on both platforms and know how to configure and secure them.
  • Command-line usage: The exam can test you on a dozen or so different commands. Seeing as how many of these commands have different switches (options), it would behoove the examinee to write down each command, its description, and an example, in an attempt to memorize each of them.
