About the CompTIA A+ Core 1 Exam

CompTIA A+ is a vendor-neutral certification designed to validate foundational skills in computer hardware, mobile devices, networking, cloud technologies, and technical troubleshooting. Candidates must pass both Core 1 (220-1201) and Core 2 (220-1202) from the same exam series to earn the full CompTIA A+ certification.

The CompTIA A+ Core 1 220-1201 examination contains a maximum of 90 questions and allows 90 minutes for completion. Question formats may include multiple-choice questions, drag-and-drop items, and performance-based questions. Candidates need a passing score of 675 on a scale of 100–900. Review the latest information on the official CompTIA A+ certification page before scheduling your examination.

Mobile Devices — 13%

The mobile devices section covers laptop components, mobile-device accessories, connection methods, and device configuration. Students learn about laptop displays, batteries, storage, memory, wireless connections, docking stations, port replicators, and mobile-device synchronization.

The CompTIA A+ Core 1 220-1201 exam preparation course also explains how to configure smartphones, tablets, and laptops for wired and wireless environments. Troubleshooting exercises help learners diagnose common connectivity, power, display, and hardware problems affecting mobile devices.

Networking — 23%

Develop a clear understanding of networking concepts, protocols, ports, devices, and connection types. The course reviews TCP/IP, DNS, DHCP, HTTP, HTTPS, SSH, RDP, email protocols, and other services commonly encountered by IT support professionals.

Learners study routers, switches, wireless access points, modems, firewalls, patch panels, network interface cards, and Power over Ethernet. Lessons also address IPv4 and IPv6 addressing, wireless standards, network cabling, internet connection types, small office networks, and common network tools.

Hardware — 25%

The hardware domain focuses on desktop computers, components, peripherals, storage devices, and printers. Students examine motherboards, CPUs, RAM, power supplies, cooling systems, expansion cards, storage interfaces, and input/output devices.

You will learn how to select compatible components, assemble computer systems, configure storage, connect peripherals, and recognize common hardware specifications. Printer coverage includes laser, inkjet, thermal, impact, and multifunction devices, together with their maintenance requirements and common faults.

Virtualization and Cloud Computing — 11%

This section introduces virtual machines, hypervisors, cloud deployment models, and cloud service models. Learners review Infrastructure as a Service, Platform as a Service, Software as a Service, and desktop virtualization.

The CompTIA A+ Core 1 220-1201 exam preparation course also covers resource allocation, virtual machine requirements, cloud file synchronization, shared resources, rapid elasticity, measured services, and high availability. These concepts support candidates preparing to work in modern hybrid and cloud-enabled IT environments.

Hardware and Network Troubleshooting — 28%

Troubleshooting is the largest Core 1 domain. Students learn how to follow a structured troubleshooting process: identify the problem, establish a probable cause, test the theory, create an action plan, implement the solution, verify system functionality, and document the outcome.

Practice scenarios cover boot failures, overheating, storage faults, display problems, power issues, printer errors, slow systems, intermittent connections, incorrect IP configurations, and wireless connectivity failures. Learners also practice choosing appropriate diagnostic tools and determining the best next action in realistic support situations.

Performance-Based Question Preparation

Knowing technical definitions is not enough for the 220-1201 examination. Candidates must also apply their knowledge to practical situations. This course includes PBQ-style exercises involving network configuration, cable selection, hardware installation, component identification, and fault diagnosis.

Detailed explanations show why each solution is appropriate and why alternative choices may not resolve the problem. This approach helps learners strengthen both technical understanding and exam-question analysis.

Who Should Enroll?

The CompTIA A+ Core 1 220-1201 exam preparation course is suitable for beginners entering the technology industry, students pursuing entry-level IT certifications, help desk professionals, desktop support technicians, field service technicians, and candidates retaking the examination.

No advanced technical qualification is required. However, basic familiarity with computers and approximately 12 months of practical IT support experience can help learners understand the applied concepts more easily.
