CompTIA A+ Certification Overview

CompTIA A+ is the most widely recognized entry-level IT certification in the world. Offered by CompTIA (Computing Technology Industry Association), A+ validates the foundational skills required to perform core IT support tasks including hardware and software troubleshooting, operating system configuration, basic networking, and security best practices.

Unlike specialized certifications that focus on specific technologies or vendors, CompTIA A+ is vendor-neutral – meaning the skills you learn apply to any hardware manufacturer, operating system, or IT environment. This universality makes A+ certified professionals valuable across industries, from small businesses to Fortune 500 companies, healthcare organizations to government agencies.

According to PrepForCerts analysis of 2026 job market data, CompTIA A+ appears in 68% of entry-level IT job postings and is explicitly required by major employers including Dell, HP, Intel, and the U.S. Department of Defense. The certification is approved for DoD 8570.01-M compliance, making it mandatory for many government IT positions.

CompTIA A+ is unique in requiring two separate exams: Core 1 and Core 2. This dual-exam structure ensures certified professionals have broad competency across both hardware/infrastructure topics and software/security topics. You must pass both exams to earn the certification.

The Two CompTIA A+ Exams Explained

CompTIA A+ certification requires passing two comprehensive exams that together validate the complete skill set needed for IT support roles:

Core 1: Hardware and Infrastructure

Focuses on mobile devices, networking technology, hardware, virtualization, and cloud computing. You'll demonstrate ability to install, configure, and troubleshoot PCs, laptops, mobile devices, and printers. Key topics include identifying components, understanding motherboard form factors, RAM types, storage technologies, and display technologies. The networking section covers TCP/IP, DNS, DHCP, and basic network troubleshooting.

Core 2: Software and Security

Covers operating systems, security, software troubleshooting, and operational procedures. You'll demonstrate proficiency with Windows, Linux, and macOS installation and configuration. Security topics include malware removal, physical security, and implementing security best practices. Operational procedures cover documentation, change management, and disaster recovery basics. This exam tests both technical skills and professional practices.

Each exam contains up to 90 questions that you must complete in 90 minutes. Question types include multiple-choice, drag-and-drop, and performance-based questions (PBQs) that simulate real-world IT scenarios. The passing score is 675 out of 900 for Core 1 and 700 out of 900 for Core 2.

Core 1 Exam Domains

The Core 1 exam covers five major domains, each weighted according to its importance in entry-level IT support:

  • Mobile Devices (15%): Laptop hardware components, mobile device connectivity, mobile device security, and troubleshooting mobile devices. Includes understanding of smartphone and tablet operating systems, accessories, and synchronization.
  • Networking (20%): Network types, protocols, ports, and network devices. Covers TCP/IP fundamentals, DNS, DHCP, wireless networking standards (802.11), and basic network troubleshooting tools like ping, traceroute, and ipconfig.
  • Hardware (25%): The largest Core 1 domain. Covers motherboards, CPUs, RAM, storage devices, power supplies, display technologies, and peripheral devices. You must identify components, understand compatibility, and perform hardware installations.
  • Virtualization and Cloud Computing (11%): Client-side virtualization concepts, cloud computing service models (IaaS, PaaS, SaaS), and cloud computing deployment models (public, private, hybrid). Understanding of virtual machine resources and hypervisors.
  • Hardware and Network Troubleshooting (29%): The methodology for troubleshooting hardware and network issues. Covers common problems with motherboards, RAM, storage, power, displays, printers, and network connectivity. Emphasizes systematic troubleshooting approach.

Core 2 Exam Domains

The Core 2 exam covers four major domains focusing on software and operational knowledge:

  • Operating Systems (31%): The largest Core 2 domain. Covers Windows installation, configuration, and management including editions, upgrade paths, and features. Also covers macOS and Linux basics, command-line operations, and operating system tools.
  • Security (25%): Physical security, logical security, wireless security, and malware types/removal. Covers social engineering awareness, password best practices, authentication factors, and implementing basic security policies.
  • Software Troubleshooting (22%): Troubleshooting Windows OS problems, application issues, and malware symptoms. Covers boot issues, system crashes, application errors, and performance problems. Includes understanding of safe mode and recovery options.
  • Operational Procedures (22%): Documentation practices, change management, disaster recovery, and environmental impacts. Covers safety procedures, communication skills, professionalism, and ticketing system usage. This domain emphasizes "soft skills" alongside technical knowledge.
Study Strategy: Many successful candidates study Core 1 and Core 2 simultaneously, as the exams complement each other. Hardware troubleshooting (Core 1) and software troubleshooting (Core 2) share similar methodologies. Plan 2-4 months of study, dedicating 1-2 hours daily. Take Core 1 first (slightly easier for most), then Core 2 within 2-4 weeks.
