12-week study plan
Weeks 1–4
Networking Fundamentals and the OSI Model
- Study the OSI and TCP/IP models in depth — understand what happens at each layer and be able to map protocols to layers quickly
- Learn IP addressing, subnetting, and CIDR notation; practice subnetting problems daily until you can calculate them under exam time pressure
- Familiarize yourself with common ports and protocols (DNS, DHCP, HTTP/S, FTP, SSH, SMTP) and the scenarios in which each is used
Weeks 5–8
Network Infrastructure, Switching, and Routing
- Study switching concepts including VLANs, STP, and link aggregation; understand how each improves network performance or redundancy
- Learn routing protocols (static routing, OSPF, BGP basics) and practice reading and interpreting route tables
- Review wireless networking standards (802.11 a/b/g/n/ac/ax), frequencies, channels, and common wireless security protocols including WPA2 and WPA3
Weeks 9–12
Security, Troubleshooting, and Exam Practice
- Focus on network security topics: firewalls, IDS/IPS, VPNs, NAC, and zero-trust concepts that are heavily weighted in the N10-009 objectives
- Work through the CompTIA troubleshooting methodology and practice applying it to scenario-based questions covering connectivity, performance, and hardware faults
- Complete at least three full-length practice exams under timed conditions, review every wrong answer, and revisit weak domains before your test date

View on Pluralsight →Exam tips
- 1.Master subnetting before exam day — at least 5–8 subnetting questions appear on every N10-009 sitting, and slow calculation will eat into your time on performance-based questions
- 2.For performance-based questions (PBQs), which appear at the start of the exam, skip any you're unsure about and return to them after completing the multiple-choice section — don't let them derail your pacing
- 3.Know the CompTIA troubleshooting methodology cold: identify the problem, establish a theory, test the theory, establish a plan, implement the solution, verify, and document — scenario questions often map directly to these steps
- 4.Study the differences between common network attack types (VLAN hopping, ARP poisoning, DNS spoofing, on-path attacks) since the N10-009 increased its security domain weighting compared to previous versions
- 5.Use the process of elimination aggressively on scenario questions — CompTIA frequently includes one answer that's technically correct but doesn't fit the described environment, so context is everything
