Performance-Based Questions (PBQs)
- PBQs appear at the beginning of the exam - don't spend too much time on them initially, flag and return later
- Practice with firewall rule configuration, log analysis, and network diagram scenarios
- Understand how to read and interpret security tool outputs (Nmap, Wireshark, SIEM logs)
- Time management is critical - don't let PBQs consume more than 25-30 minutes total
- Use the CompTIA Lab Simulator or Jason Dion's PBQ practice for hands-on experience
Memorization Techniques
- Create acronyms for port numbers: 'HTTP Has 80 Teeth, HTTPS Has 443 Swords, SSH Has 22 Keys'
- Use the phrase 'Some People Fear Change' for incident response: Preparation, Identification, Containment, Eradication, Recovery, Lessons Learned
- Draw out network architectures repeatedly until you can diagram DMZs, VLANs, and segmentation from memory
- Create comparison tables for similar concepts (IDS vs IPS, TACACS+ vs RADIUS, symmetric vs asymmetric encryption)
- Use spaced repetition with Anki or Quizlet for terms and definitions
Domain-Specific Focus
- Prioritize Security Operations (28%) and Threats/Vulnerabilities (22%) - these represent 50% of your exam
- Don't neglect lower-weighted domains completely, but allocate study time proportionally
- For Security Operations, focus heavily on incident response lifecycle and SIEM log analysis
- In Threats domain, be able to identify attack types from scenario descriptions in under 30 seconds
- For Security Architecture, practice explaining WHY certain designs are more secure
Practice Exam Strategy
- Take your first practice exam after Week 4-5 to identify weak areas early
- Don't just review wrong answers - understand why right answers are correct
- Aim for consistent 85%+ scores on practice exams before scheduling the real exam
- Take at least 3-4 full-length practice exams under timed conditions
- Use practice exam analytics to focus final review on specific weak domains
- Don't memorize practice questions - understand the underlying concepts
Active Learning Techniques
- Set up a free tier cloud account (AWS/Azure) to explore security configurations hands-on
- Use VirtualBox or VMware to create a home lab with vulnerable machines
- Join TryHackMe or HackTheBox and complete beginner security challenges
- Teach concepts to someone else or record yourself explaining topics
- Create your own scenarios and quiz questions based on real-world security situations
- Watch security news and relate current events to exam concepts
Exam Registration and Scheduling
- Schedule your exam 2-3 weeks in advance to create urgency and prevent procrastination
- Consider online proctoring (OnVUE) for convenience, but ensure a quiet, clean testing space
- Read the testing center or online proctoring requirements thoroughly
- Schedule your exam for your peak mental performance time (morning for most people)
- Complete a system test before exam day if testing online
- Have a valid government-issued ID ready that matches your registration name exactly
Final Week Preparation
- Focus on review rather than learning new material in the last 3-4 days
- Create a one-page 'cheat sheet' of items you struggle with most (ports, acronyms, formulas) - review it morning of exam
- Take one final practice exam 3 days before to build confidence
- Get adequate sleep for the 2 nights before the exam - not just the night before
- Do light review the day before rather than intense cramming
- Visualize yourself successfully completing the exam
Exam Day Tips
- 1Arrive 15-30 minutes early for testing center exams; start online exams 30 minutes before appointment for check-in
- 2Bring two forms of ID for testing centers; have government-issued ID ready for online proctoring
- 3Do a 'brain dump' of memorized items (ports, acronyms, formulas) on the provided materials immediately after the tutorial
- 4Read questions carefully - CompTIA often includes scenarios where multiple answers seem correct; choose the BEST answer
- 5Flag difficult questions and move on - don't let one question derail your momentum
- 6Manage your time: aim to complete multiple-choice questions at roughly 1 minute per question
- 7For scenario-based questions, identify the core security principle being tested before answering
- 8If you encounter PBQs at the start, skim them, flag difficult ones, and return after completing multiple-choice questions
- 9On performance-based questions, read all instructions carefully before clicking - some PBQs have multiple parts
- 10Eliminate obviously wrong answers first, then choose between remaining options
- 11Trust your preparation - your first instinct is usually correct unless you find a clear error
- 12Use the entire 90 minutes if needed - review flagged questions and double-check answers if time permits
- 13Stay calm if you encounter unfamiliar content - the exam is designed so you can miss some questions and still pass
- 14Remember that you need 750/900 (approximately 83%) to pass - perfection is not required
