Take our free CompTIA A+ practice test with Smart Practice questions. Unlimited practice for Core 1 and Core 2 exams with instant feedback, detailed explanations, and progress tracking—no credit card required.
The CompTIA A+ certification is the most widely recognized entry-level IT credential in the world. Earning it proves you can install, configure, and troubleshoot hardware, software, and networking components in a professional environment. A practice test is the single most effective way to bridge the gap between reading a textbook and performing under exam conditions. Research consistently shows that retrieval practice—actively recalling information—leads to stronger long-term retention than passive review alone.
Our free practice test removes the biggest barrier to quality exam prep: cost. Many premium question banks charge $50–$150 for static question sets that never change. With our Smart Practice engine, you receive fresh, unique questions every session, ensuring you build genuine understanding rather than memorizing answer patterns.

| Virtualization & Cloud | 11% | Cloud models, virtual machines, containers |
| Troubleshooting | 29% | Methodology, hardware, networking, storage issues |
| Domain | Exam Weight | Key Topics |
|---|---|---|
| Operating Systems | 31% | Windows, macOS, Linux, command-line tools |
| Security | 22% | Malware, encryption, authentication, physical security |

Q1: A technician needs to connect a laptop to a projector that only has a VGA input. The laptop has HDMI and USB-C ports. Which adapter should the technician use?
A) HDMI to DisplayPort B) USB-C to VGA C) HDMI to DVI D) USB-A to VGA
Answer: B) USB-C to VGA
USB-C supports video output via DisplayPort Alt Mode, and a USB-C to VGA adapter converts the digital signal to the analog VGA format the projector requires. HDMI to DisplayPort would not reach VGA, and USB-A does not carry video signals.
Q2: A user reports that their Windows workstation takes over five minutes to boot. Task Manager shows 98% disk usage. Which component should the technician recommend upgrading?
A) RAM B) CPU C) HDD to SSD D) Network adapter
Answer: C) HDD to SSD
Sustained 98% disk usage during boot strongly suggests the mechanical hard drive is the bottleneck. Replacing it with an SSD dramatically reduces read/write latency and boot times, often from minutes to seconds.
Q3: Which Windows command-line tool displays the IP configuration of all network adapters?
A) netstat B) nslookup C) ipconfig /all D) ping
Answer: C) ipconfig /all
The ipconfig /all command displays detailed IP configuration for every network adapter, including IPv4/IPv6 addresses, subnet masks, default gateways, DNS servers, and DHCP lease information.
Traditional practice tests rely on a fixed pool of 200–500 questions. Once you cycle through them, you start recognizing answer patterns rather than learning the material. Our Smart Practice engine solves this by generating unique questions on demand using large language models trained specifically on CompTIA A+ exam objectives.
Each question goes through multiple validation steps: objective alignment verification, distractor quality assessment, and difficulty calibration. The result is an effectively unlimited question bank that stays fresh and exam-accurate. Because the engine understands the relationships between topics, it also generates context-aware explanations that connect concepts across domains—helping you see how hardware, networking, and troubleshooting skills work together in real IT support scenarios.
