CompTIA Certification Exam Prep

CompTIA certifications are vendor-neutral and widely recognized across IT support, infrastructure and security roles, which makes them portable in a way vendor credentials are not. The path starts at A+ (Core 1 and Core 2) for entry-level technicians, continues through Network+, Security+, Linux+ and Server+ at the infrastructure and associate level, and reaches CySA+ for security analysts working in a SOC. Most CompTIA credentials hold ANSI accreditation under ISO/IEC 17024.

Exams mix multiple choice with performance-based questions, which drop you into a simulated console or drag-and-drop scenario and ask you to apply a concept rather than recognize it. Most run 90 minutes with up to 90 questions; CySA+ runs 165 minutes and leans heavily on analysis. Scoring is on a 100-900 scale, and A+ is the exception that requires passing two separate exams, Core 1 and Core 2, to earn the credential. Certifications last three years and renew through continuing education.

Career outcomes: Security+ is the highest-demand CompTIA credential and an approved baseline certification under the DoD 8140 framework (which replaced DoD 8570), making it a hiring gate for many federal and defense contracts. A+ remains the standard ask for help desk and field technician roles, Network+ for network support, CySA+ for SOC analyst and threat detection work, and Linux+ and Server+ for infrastructure and datacenter positions.

What you will study: hardware components and troubleshooting methodology, operating system installation and configuration across Windows, macOS and Linux, networking topologies, protocols, subnetting and wireless standards, security fundamentals covering threats, cryptography, identity management and risk, incident response and log analysis, vulnerability management and SIEM tooling, Linux command line, permissions, systemd and shell scripting, and server hardware, RAID, virtualization, storage and disaster recovery planning.
