SY0-801 Complete Learning Guide

Pass the exam. Understand security. Use it at work the next morning.

SY0-801 V8 Complete Learning Guide is an independent, unofficial study guide written to help you prepare for the CompTIA Security+® certification exam SY0-801 V8. It follows the publicly available exam objectives (objectives document version 2.0) domain by domain and objective by objective, so you always know where you are and what is left.

The book is written for network and security engineers and IT professionals who want more than a list of definitions. Every topic is explained with rules of thumb, diagrams and real-world examples from enterprise networks, so you learn to choose the best answer in scenario questions, which is exactly what the exam tests.

• 27 chapters, one for each exam objective, organised into the five exam domains
• 339 pages with around 50 diagrams and charts, comparison tables and configuration examples
• 135 Knowledge Check questions with a clear explanation for every answer
• 15 performance-based scenarios (PBQ labs) with worked solutions: log analysis, firewall rule review, email security records, risk calculations, zone design and more
• Appendix A: High-Impact Scenarios and Use Cases. 10 well-known real incidents analysed through the exam objectives, plus 50 short exam-style scenarios with answers
• Exam strategy and PBQ tactics, a cheat sheet (formulas, ports, key comparisons, process sequences) and a glossary of 120+ acronyms
• A suggested eight-week study plan
