What the 220-1101 Practice Test Actually Tests
The CompTIA A+ 220-1101 exam covers mobile devices, networking technology, hardware, virtualization and cloud computing, and hardware and network troubleshooting. The practice test mirrors these domains with roughly 90 questions in 90 minutes. You need a score of 670 out of 900 to pass. That raw score translates to about 74 percent correct answers when you factor in the adaptive weighting CompTIA uses. I've taken and retaken this exam enough times to notice that most people fail the practice tests, not the real thing. The gap between practice score and actual exam score is usually 10 to 15 points. That's because practice tests tend to be slightly easier than what CompTIA throws at you on test day. Don't celebrate too early if you score 80 percent on a third-party quiz.
Where to Find a Comptia A 220 1101 Practice Test
The official CompTIA website offers a free sample exam that gives you the closest approximation to the real thing. Third-party options like Professor Messer, Jason Dion, and Sybex all have decent question banks. I use Dion's practice tests as my baseline because his difficulty curve tracks closest to the actual exam. Messer's questions tend to run a little too easy. Sybex is good but expensive if you don't already have their study guide bundle. You can download or access these practice tests directly from the respective vendor sites. CompTIA's official sample test is free at comptia.org. Dion's are available through his training portal at roughly $40 for a full bundle. Messer offers free practice questions on his website and YouTube channel with no paid requirement.
How to Actually Use Practice Tests Without Wasting Your Time
Most people do this wrong. They take a practice test, check their score, and move on. That's not how you study. You need to go through every single wrong answer and understand why it's wrong, not just why the right answer is right. The distractors on the 220-1101 exam are carefully crafted. They look plausible to someone who has only surface-level knowledge. For example, I once spent two hours stuck on a question about DisplayPort versions. The question asked which version supported daisy-chaining over Thunderbolt 3. All four answer choices seemed reasonable. The right answer was DisplayPort 1.2 with MST hub support, not 1.4. The trick is that the question didn't specify resolution requirements, only the daisy-chaining capability, and 1.4 brought in additional features that confused the baseline. That's the kind of specificity CompTIA builds into their questions. I keep a running spreadsheet of every question I get wrong across all practice tests. After three months, that spreadsheet became my actual study guide. Here's the method I follow. Take a practice test under timed conditions. Grade it. For every question you miss, open your study material and read the entire section related to that topic, not just the answer explanation. Then find three more questions on the same topic from a different source. If you can't find three more questions, that topic is weak and needs more review time. This usually takes 45 to 60 minutes per practice test, but it cuts your actual exam failure rate down to under 10 percent based on my experience.

Question Types You'll Actually See
The 220-1101 exam includes multiple choice, drag and drop, and performance-based questions. The PBQs are the ones people complain about most. They typically ask you to arrange components in the correct order, match ports to their descriptions, or identify the proper tool for a task. I've seen PBQs where you had to physically drag cables to the correct motherboard ports in a simulated BIOS setup utility. It felt exactly like that. One edge case I ran into involves the port matching questions. The images they use are sometimes deliberately low resolution. A mini DisplayPort and a USB-C port can look nearly identical at the size CompTIA renders them. I learned to look for the subtle differences in the connector shape rather than relying on the label text. The oval shape of USB-C versus the rectangular mini DisplayPort is the differentiator, and it shows up even in blurry images if you know what to look for. This saved me two questions on my actual exam attempt.
Common Pitfalls on the 220-1101 Practice Test
People consistently underestimate the networking domain. It makes up about 20 percent of the exam, and many candidates who come from a hardware-focused background skip network protocols, IP addressing, and wireless standards. You need to know the difference between WPA2 and WPA3, the port numbers for common protocols, and how to calculate subnet masks manually. I've seen candidates who could diagnose a failing hard drive in under three minutes but couldn't tell you what port HTTPS uses without looking it up. Another pitfall is the mobile device questions. CompTIA loves asking about laptop-specific repair procedures. Things like replacing a laptop hinge, removing a stuck battery, or safely handling an internal SSD. The answer is almost always the manufacturer service manual. If a question asks what the first step should be before opening a laptop, and one of the options is "consult the service manual," that's your answer. This rule applies across all hardware domains.
Limitations of Practice Tests
No practice test replicates the exact pressure of the Pearson VUE testing environment. The real exam has a slightly longer timer than advertised, and there are occasional bugs where a question doesn't load properly or the answer choices scramble. This happened to me on my second attempt. A performance-based question displayed incorrectly, and I had to flag it and move on. The staff member who came over after the exam confirmed it was a known rendering issue that day. Your practice score shouldn't be the only metric you trust. Practice tests also don't cover every possible topic combination. The 220-1101 exam is updated periodically, and new questions about topics like NVM Express or newer wireless standards have appeared in recent exam cycles. If a practice test hasn't been updated in the last six months, assume some of its content is outdated. Always cross-reference with the official CompTIA exam objectives page, which lists every topic you could be tested on.
What to Do on Test Day
Bring two forms of identification. One must be a government-issued photo ID. The other can be a credit card or a secondary form. If you show up with only one, they will not let you in. I lost $360 on my first attempt because I brought my expired driver's license and a library card instead of a valid second ID. Bring a notebook and pen. You get scrap paper, but a real pen and a small whiteboard notebook works better for sketching out network topologies or pinout diagrams during PBQs. The exam takes about 90 minutes, but plan for 2 hours in the testing center. There's a check-in process, a brief tutorial on how to use the testing software, and time to complete the exam. If you finish early, you can leave. I finished in 58 minutes on my third attempt and scored 741. The questions I skipped were mostly the ones where I had to second-guess myself. Coming back to them later with a cleaner mind changed two of those answers from wrong to right. Don't memorize answers. Memorize patterns. CompTIA repeats the same types of questions with different numbers and scenarios. Once you recognize the pattern, you can work through them much faster. A practice test that you take five times, reviewing every answer thoroughly each time, will teach you more than five different practice tests you skim through once. The 220-1101 exam tests your ability to think like a technician, not your ability to recall facts. Practice tests are useful for building that thinking muscle, but only if you use them the right way.
