Build it. Secure it. Fix it. Learn networking from the ground up and pass the CompTIA Network+ exam with confidence.
Every app, video call and cloud service runs on a network, and employers need people who can design, secure and troubleshoot one. This CompTIA Network+ course gives you the skills and confidence to do exactly that, and to pass the Network+ N10-009 exam on your first attempt. Across 15 narrated video modules, you’ll follow one growing company from a single office to a multi-site, hybrid-cloud network. You’ll learn every exam objective through clear diagrams, real commands and realistic scenarios, not memorized lists. Then you’ll prove you’re ready with a full-length, 90-question Network+ practice exam.
What You'll Learn
- Explain the OSI model, ports and protocols, and how data really moves across a network
- Subnet IPv4 networks quickly and confidently, and work with IPv6 addressing
- Configure routing, switching, VLANs and spanning tree, and design reliable networks
- Deploy and secure wireless networks with Wi-Fi 6/7, WPA3 and enterprise authentication
- Understand cloud networking, SDN, SD-WAN, zero trust and infrastructure as code
- Recognize network attacks, from DDoS and DNS poisoning to phishing, and apply the right defenses
- Troubleshoot like a pro with CompTIA's seven-step method and tools like ping, tracert, dig, Nmap and Wireshark
- Document, monitor and protect networks with change management, SNMP, baselines and disaster recovery plans
What's Included
- 15 video modules (about 7 hours of narrated lessons), aligned to every N10-009 exam objective
- Full-length Network+ practice exam: 90 questions, timed like the real exam, plus six performance-based practice tasks
- Every answer explained, with a domain-by-domain score sheet that tells you exactly which modules to review
- Slide decks and audio for each module, so you can review on the go
- Knowledge checks at the end of every module
- Exam strategy lesson covering question types, time management and must-know ports
