How to Pass CompTIA A+ Core 1 (220-1201) in 2026: Complete Study Guide
CompTIA A+ Core 1 covers hardware, networking, mobile devices, and troubleshooting — the foundation for any IT support career. This guide covers all 5 domains, the performance-based question format, and a 6-week study plan to pass 220-1201 on your first attempt.
CompTIA A+ is the most recognized entry-level IT certification in the world, and Core 1 (220-1201) is the first of two exams you must pass to earn it. This exam tests your knowledge of hardware, networking, mobile devices, virtualization, and troubleshooting — the exact skills employers expect from a help desk technician or field service engineer on day one. This guide walks you through every domain, explains the performance-based question format, and gives you a concrete 6-week plan to pass on your first attempt.
What Is CompTIA A+ Core 1?
CompTIA A+ Core 1 (exam code 220-1201) is the hardware and infrastructure half of the A+ certification. It focuses on the physical and logical skills that every IT support professional needs: identifying and installing hardware components, configuring network connections, supporting mobile devices, understanding cloud and virtualization basics, and diagnosing hardware and network issues systematically.
A+ Core 1 is designed for:
- Entry-level IT support technicians and help desk staff
- Field service technicians who install, configure, and repair hardware
- Career changers moving into IT from a non-technical background
- Students in IT programs who want a vendor-neutral credential employers recognize

All 5 Exam Domains
| Domain | Weight | Key Topics |
|---|---|---|
| 1. Mobile Devices | 15% | Laptop components (RAM, storage, displays, keyboards), tablet and smartphone hardware, mobile OS features, accessories and ports |
| 2. Networking | 20% | TCP/IP fundamentals, IPv4/IPv6, DHCP, DNS, common ports and protocols, wireless standards (802.11 a/b/g/n/ac/ax), network hardware (switches, routers, access points), cable types |
| 3. Hardware | 25% | RAM types (DDR4/DDR5, ECC, SO-DIMM), storage (SATA, NVMe, M.2), CPU architecture, motherboard components, PCIe slots, power supplies, display types and connectors, printers |
| 4. Virtualization and Cloud Computing | 11% | Hypervisors (Type 1 vs Type 2), VMs vs containers, cloud service models (IaaS/PaaS/SaaS), deployment models (public/private/hybrid/community), cloud storage concepts |
| 5. Hardware and Network Troubleshooting | 29% | CompTIA's 7-step troubleshooting methodology, diagnosing RAM/CPU/storage/display failures, network connectivity troubleshooting, wireless issues, printer troubleshooting, mobile device issues |
Hardware and Network Troubleshooting at 29% is the single heaviest domain — do not underestimate it. Candidates who memorize hardware specs but skip troubleshooting scenarios consistently fail.
Performance-Based Questions Explained
Performance-based questions (PBQs) are simulations or interactive tasks that appear at the start of the exam. Instead of choosing from four options, you might be asked to:
- Drag and drop network devices into the correct positions in a diagram
- Configure IP settings in a simulated Windows or Linux interface
- Match cable types to the correct use cases
- Identify a hardware component from a photo or diagram
- Order the steps of the CompTIA troubleshooting methodology
Core 1 + Core 2: The Full A+ Requirement
CompTIA A+ certification requires passing two separate exams. Core 1 (220-1201) and Core 2 (220-1202) are independent — you can take them in any order and there is no combined exam. Each exam costs $246, so the full certification costs $492 if you pass both on your first attempt.
Core 1 vs Core 2 focus areas:
- Core 1 (220-1201): Hardware, infrastructure, networking, mobile devices, virtualization
- Core 2 (220-1202): Operating systems (Windows, Linux, macOS, mobile OS), security, software troubleshooting, operational procedures
Most candidates study and sit for Core 1 first because hardware knowledge is foundational — understanding how components work makes OS-level troubleshooting in Core 2 easier to learn.
6-Week Study Plan
| Week | Focus | Daily Goal (~1.5 hrs) |
|---|---|---|
| Week 1 | Hardware (Domain 3) | RAM types, storage interfaces (SATA vs NVMe), PCIe, power supplies, connector identification |
| Week 2 | Networking (Domain 2) | TCP/IP, DHCP, DNS, common ports, wireless standards, cable types, network devices |
| Week 3 | Mobile Devices + Virtualization (Domains 1 & 4) | Laptop teardown components, smartphone connectors, cloud service models, hypervisor types |
| Week 4 | Troubleshooting (Domain 5) | CompTIA 7-step methodology, hardware failure symptoms, network connectivity scenarios, printer issues |
| Week 5 | Practice Exams + Weak Areas | Full practice exams, review every missed question, revisit any domain below 70% |
| Week 6 | Final Review + Exam | Speed drills on connector types and ports, PBQ practice, light review 2 days before — do not cram the night before |

Exam Day Strategy
- Flag PBQs and move on if stuck. Each PBQ can cost you 5–8 minutes. Multiple-choice questions are faster and worth the same or more in aggregate.
- Use process of elimination aggressively. On hardware questions with unfamiliar terms, eliminate clearly wrong answers first — you can often narrow to 2 choices even without certainty.
- Watch for "most appropriate" phrasing. Many questions have two technically correct answers; CompTIA asks for the best or most appropriate one given the scenario constraints (cost, speed, ease of deployment).
- Do not leave questions blank. There is no penalty for guessing. If time is running short, select your best guess for any flagged questions before the timer ends.
- Aim for 75%+ on practice exams before booking. A 5-point buffer above the 70% passing threshold accounts for test-day nerves and slightly harder live questions.
