CompTIA Certification Guides
CompTIA certification guides for A+, Network+, Security+, Project+, Cloud+, Linux+, Data+, CySA+, PenTest+, SecurityX, and AI Essentials.
CompTIA remains the broadest early-career and mid-career vendor section on the site. These guides are written around the choices CompTIA exams actually score: the safest next troubleshooting step, the right control for the constraint, the correct document or register to update, and the difference between recognizing a term and applying it under pressure.
Published exam guides currently include A+ Core 1, A+ Core 2, Network+, Security+, Project+, Cloud+, Linux+, Data+, CySA+, PenTest+, SecurityX, and AI Essentials.
Start with the exam that matches your target path, then use the cheat sheet for troubleshooting or scenario recall, the FAQ for scenario traps and format questions, and the resources page for CompTIA exam references.
