- Networking Concepts (23%) — Foundations: OSI model, TCP/IP, addressing, subnetting, wireless standards
- Network Implementation (20%) — Practical deployment: routing protocols, VLANs, WAN technologies
- Network Operations (18%) — Real-world management: monitoring, SNMP, documentation, policies
- Network Security (21%) — Protection strategies: attacks, firewalls, VPNs, AAA, access control
- Network Troubleshooting (18%) — Diagnostics: tools, methodology, hardware and wireless issues
Your 7-Week Study Plan
Week 1: Domain 1 Part 1 — Foundations (10–12 hours)
Focus: OSI Model, TCP/IP Model, Ports, and Protocols
This is your foundation week. Everything in networking builds on these concepts.
Topics to cover:
- OSI model deep dive (all 7 layers, what happens at each, memory tricks)
- TCP/IP model (comparison to OSI)
- Common ports and protocols (memorize at least the top 25: HTTP/80, HTTPS/443, FTP/20-21, SSH/22, Telnet/23, SMTP/25, DNS/53, DHCP/67-68, POP3/110, IMAP/143, RDP/3389, and more)
- Port classifications (well-known, registered, dynamic/private)
- Connection-oriented vs. connectionless protocols (TCP vs. UDP)
Study tips:
- Create flashcards for ports and protocols—you'll need instant recall on test day
- Draw the OSI model by hand repeatedly until it's automatic
- Watch packet flows through the OSI layers to understand where each protocol operates
Practice: Complete 50+ questions focused on this content. Aim for 75%+ accuracy before moving forward.
Week 2: Domain 1 Part 2 — Addressing, Subnetting, Routing & Wireless (10–12 hours)
Focus: IP Addressing, Subnetting, Routing Basics, Wireless Standards
Topics to cover:
- IPv4 addressing (classes, CIDR notation, private vs. public ranges)

- You can walk through the troubleshooting methodology in your sleep
- You've reviewed all five domains at least twice
Study Tips for Success
1. Use Quality Study Materials
Not all practice questions are equal. Aim for materials that closely mirror the actual exam. LearnZapp's CompTIA question bank includes 10,524+ questions sourced from Wiley—the same provider CompTIA uses. Start with a free diagnostic test to identify your baseline and personalize your study path.
2. Diversify Your Learning
- Watch video lectures for visual learners
- Use flashcards for memorization
- Take practice exams for adaptation
- Read documentation and white papers for deep understanding
- Study with a partner for accountability
3. The Subnetting Non-Negotiable
We can't stress this enough: subnetting appears on almost every Network+ exam. If you struggle with subnetting during practice exams, allocate extra time to it immediately. Don't move forward feeling uncertain about this skill.
4. Time Management During the Exam
You have 90 minutes for 90 questions—one minute per question on average. However:
- MCQs typically take 30–60 seconds
- PBQs take 3–5 minutes
- Budget your time accordingly
- If stuck on a PBQ, mark it and move on
5. Create Your Own Review Materials
- Write flashcards for protocols and ports
- Build a one-page subnetting reference (then memorize it)
- Create a troubleshooting flowchart
- Draw the OSI model from memory daily
6. Simulate Exam Conditions
For each practice exam:
- Use a quiet environment
- Turn off notifications
- Set a timer for exactly 90 minutes
- Don't use notes or references
- Score it honestly
7. Understand, Don't Memorize
While some memorization is necessary (ports, protocols), prioritize understanding why technologies work the way they do. When you understand the underlying concepts, you can reason through unfamiliar scenarios on test day.
What to Expect on Exam Day
The Network+ N10-009 exam will test:
- Your ability to think like a network administrator
- Quick decision-making under pressure
- Practical troubleshooting skills (PBQs often present network diagrams and ask you to identify issues)
- Knowledge retention across five interconnected domains
You'll encounter questions like:
- "A user reports they can't access a web server. Walk through your troubleshooting steps."
- "Given this network topology and security requirements, which routing protocol would you recommend and why?"
- "Calculate the number of usable hosts on a /26 network."
- "Identify the attack shown in this packet capture and describe appropriate mitigation."
Success means integrating knowledge from multiple domains to solve realistic networking problems.
The Home Stretch
Following this seven-week plan requires discipline. You'll spend 70–84 hours studying over seven weeks. That's significant but manageable with a consistent schedule.
Here's the reality: the time you invest in daily practice—especially subnetting—directly correlates with your exam score. Candidates who ace the subnetting questions and spend time on PBQs typically score in the 80%+ range.
Your goal isn't just to pass; it's to demonstrate genuine networking competency. This certification opens doors to roles in network administration, support, and infrastructure. The knowledge you build over these seven weeks will serve you in your IT career, not just on test day.
