How to Pass CompTIA A+ Core Series: The IT Career Launchpad

A+: Where Every IT Career Begins

CompTIA A+ is the most widely recognized entry-level IT certification. It covers hardware, software, networking, and security fundamentals that every IT professional needs. For cybersecurity careers specifically, A+ provides the systems knowledge that security tools and concepts build upon — you need to understand how computers and networks work before you can secure them.

A+ requires two exams: Core 1 (220-1101) and Core 2 (220-1102). Each has up to 90 questions in 90 minutes with a passing score of 675/900 (Core 1) and 700/900 (Core 2).

Core 1 (220-1101) Strategy

Mobile Devices (15%)

Covers laptops, smartphones, and tablets. Key topics: laptop components (RAM, storage, battery, display), mobile device connectivity (Bluetooth, NFC, cellular), mobile device accessories, and mobile OS features (Android, iOS).

Networking (20%)

Covers network fundamentals. Key topics: TCP/IP, common ports, networking hardware (routers, switches, APs, firewalls), wireless standards (802.11a/b/g/n/ac/ax), network types (LAN, WAN, PAN, MAN, WLAN), and basic network troubleshooting (ipconfig, ping, tracert, nslookup, netstat).

This is the highest-weighted Core 1 domain and the most relevant for cybersecurity careers. Do not rush through it.

Hardware (25%)

Covers PC components and peripherals. Key topics: motherboard form factors, CPU architectures, RAM types (DDR4, DDR5), storage types (SSD, HDD, NVMe, M.2), power supplies, display technologies, printer types and maintenance.

Virtualization and Cloud Computing (11%)

Covers virtualization concepts and cloud models. Key topics: hypervisor types (Type 1 and Type 2), VM resource allocation, cloud deployment models (public, private, hybrid), cloud service models (IaaS, PaaS, SaaS).

Hardware and Network Troubleshooting (29%)

The largest Core 1 domain. Covers systematic troubleshooting of hardware and network issues. Key methodology: identify the problem → establish a theory → test the theory → establish a plan → implement → verify → document.

Core 2 (220-1102) Strategy

Operating Systems (31%)

The largest Core 2 domain. Covers Windows (10/11), macOS, Linux, and Chrome OS. Key topics: Windows installation and upgrade paths, Windows features (Task Manager, Event Viewer, Registry, Group Policy), command line tools (sfc, chkdsk, diskpart, gpresult), macOS/Linux basics.

For cybersecurity: Pay special attention to Windows Event Viewer, Registry, and Group Policy — these are essential tools for security analysis and hardening.

Security (22%)

Directly relevant to cybersecurity careers. Key topics: physical security (badge readers, cameras, locks), logical security (firewalls, anti-malware, authentication), wireless security (WPA2, WPA3), social engineering (phishing, tailgating, shoulder surfing), Windows security features (BitLocker, EFS, Windows Defender), mobile device security (MDM, screen locks, remote wipe), and browser security.

Software Troubleshooting (22%)

Covers OS and application troubleshooting. Key topics: blue screen troubleshooting, application crashes, slow performance diagnosis, malware removal process (identify, quarantine, disable System Restore, remediate, schedule scans, enable System Restore, educate user).

The malware removal process is a frequently tested topic. Memorize the seven-step process.

Operational Procedures (25%)

Covers documentation, change management, and professionalism. Key topics: ticketing systems, asset management, change management best practices, backup procedures (full, incremental, differential), data destruction methods, and safety procedures (ESD, electrical safety).

Study Plan

For Core 1 (Weeks 1-5):

For Core 2 (Weeks 6-10):

Take Core 1 first, then Core 2. The knowledge builds sequentially.

PBQ Preparation

A+ has PBQs on both exams. Common types:

Practice these with hands-on virtual labs and CyberCertPrep's A+ question bank featuring practical scenario-based questions for both Core 1 and Core 2.
