Comptia A 1002 Exam Objectives

Let's talk about the CompTIA A+ 1002 Exam Objectives

Most people treat the A+ like it's two separate exams you have to pass. It's not. The 1002 objective list is the second half of the certification, and it covers everything from hardware to mobile devices to networking to operational procedures. You already should know the basics from 1001. If you don't, you're going to have a rough time here. I studied for this back when they still called it the 220-802. The objectives have shifted since then, but the core material hasn't changed much. Hardware still matters. Networking still matters. The operational side gets more attention now than it used to.

CompTIA A+ 1002 Exam Objectives breakdown

Let me walk you through what's actually on the list and what tripped people up when I was teaching this material. Hardware: 22% of the exam. This is where the bulk of the questions live. Printers are a nightmare for most test-takers. Not because the concepts are hard, but because there are so many specific details about toner, fusers, rollers, and maintenance cartridges that memorization feels endless. I once had a student who could name every type of printer mechanism but still failed two practice tests because he kept mixing up which printer type uses UV light to cure the toner. It's the laser printer. Not the inkjet. Not the thermal. I told him to draw a diagram of each printer type on a whiteboard and label every component. It took him 45 minutes and he remembered it for the rest of the week. Hard drives and SSDs are simpler now than they were a few years ago. You need to know the form factors, the interfaces, the power connectors, and the specs. Know that M.2 has two different key types. Know that PCIe NVMe is different from SATA M.2 even though they use the same physical slot. People lose points on this constantly.

Mobile devices: 14%. Laptops, tablets, phones. This section is smaller but surprisingly dense. You need to know how to replace a laptop battery, how to upgrade RAM on different form factors, how to troubleshoot backlight issues, and the differences between LCD and LED and OLED panels. The exam loves asking about ESD precautions during mobile device repair. Static discharge doesn't care how experienced you are. I've seen certified techs fry $400 logic boards because they didn't bother with a wrist strap on a "quick job." There's also the whole section on mobile device ports and connectivity. USB-C reversible connectors. DisplayPort Mini. Thunderbolt. You need to know which ones carry video, which ones don't, and what speeds they support. The object version numbers (3.0, 3.1, 3.2) are intentionally confusing. CompTIA tests this on purpose. Networking: 18%. This is where the exam gets real. You need to know IP addressing, subnetting, DNS, DHCP, ports and protocols, network topologies, hardware like routers and switches and access points, and wireless standards. Yes, you will get subnetting questions. Not complex ones, but basic /24 and /28 questions that test whether you actually understand what a subnet mask does.

I keep seeing people memorize port numbers without understanding the protocols behind them. They'll know port 443 is HTTPS but they won't be able to explain why you'd use it over port 80. Learn the why. The exam gives scenarios, not trivia. Operational procedures: 16%. This section covers things like documentation, communication skills, safety, environmental issues, and professionalism. It sounds fluffy but it accounts for a real chunk of the exam. Questions about proper disposal of toner cartridges, handling hazardous materials, working with customers who are frustrated, and writing clear documentation. The professional standards questions are the ones nobody studies for. They show up at the end of the exam when you're already tired. I recommend reviewing this section twice: once at the beginning so it's fresh, and once near the end when you're sharpening your test-taking stamina.

Software troubleshooting: 16%. OS installation, configuration, troubleshooting, and security. You need to know how to install and configure Windows, Linux, and macOS. Not just the steps, but the common problems that come up. Boot issues, driver conflicts, update failures. Security is huge here. Malware removal, firewalls, encryption, access controls, social engineering prevention. Virtualization and cloud computing: 10%. This is the newer material. Hypervisors, virtual machines, cloud service models, SaaS, PaaS, IaaS. Cloud storage and deployment models. The percentage is small but the questions can be tricky because the definitions overlap.

How to actually study this

Get the official CompTIA A+ Core 1 and Core 2 objectives from their website. Print them out. Go through each one and mark it as confident, shaky, or completely lost. Your study plan should be built around the shaky and lost items. The confident stuff can wait. Use a combination of a good review book, video course, and practice tests. Not just practice tests, because rote memorization from practice questions will fail you on scenario-based questions. The exam has moved away from simple definition recall. You'll get a scenario and have to pick the best answer from four reasonable options. Here's something most guides won't tell you: the hardest part of the A+ exam isn't the technical content. It's the wording. CompTIA writes questions deliberately. Wrong answers often contain partially correct information. The right answer is the most correct, not the perfectly correct. Practice reading every word carefully. If an answer choice says "always" or "never," it's probably wrong. In IT, very few things are absolute.

One specific edge case that comes up: you'll get questions about diagnosing a problem where multiple symptoms point to different causes. The exam wants you to pick the most likely cause based on the information given, not the one you'd chase down first in a real shop. In practice, you might swap the power supply before checking the motherboard. On the exam, you follow the troubleshooting methodology in order. Memory management first, then peripheral checks, then power, then motherboard. Stick to the process even when it feels inefficient. The exam is 90 minutes, 90 questions, and requires a score of 720 out of 900. It's not easy, but it's fair if you've put in the time. Don't buy into the idea that you can cram for this. Three to four months of consistent study is more realistic than any crash course. The official objectives document is free on the CompTIA website. Download it. Bookmark it. Revisit it weekly. Everything else is just supporting material.
