• Week 6: Domain 3: Physical Security — Data center access controls, Environmental monitoring, Fire suppression
• Week 7: Domain 3: Server Hardening — Patch management, Firewalls, Encryption, Certificate management
• Week 8: Domain 3: Identity & Access — RBAC, MFA, SIEM, Auditing, Data sanitization
• Week 9: Domain 4: Troubleshooting — Hardware diagnostics, RAID rebuild, Network issues, Boot failures
• Week 10: Full Review: Practice tests, Hands-on labs, PBQ practice, Exam logistics

Top Study Tips

1. Start with the official exam objectives. Download them from the CompTIA website and use them as your study checklist. Every exam question maps to a specific objective.

1. Use active recall over passive reading. Instead of re-reading notes, test yourself with practice questions after each study session. This dramatically improves retention.

1. Focus on heavily-weighted domains first. Domains with higher percentages appear more on the exam. Master these before moving to lower-weighted areas.

1. Build hands-on experience. Set up a lab environment and practice the skills you are studying. Hands-on experience is especially valuable for performance-based questions.

1. Take practice exams under real conditions. Time yourself, eliminate distractions, and simulate the exam environment. Review every wrong answer and understand why it was wrong.
