Korshub's take

A condensed review of all five domains

This video compresses the N10-009 into about 2.5 hours, covering each of the five exam domains with its own chapter. The chapters are timestamped, so you can jump straight to the domain you find hardest.

What the domains cover

Networking concepts, including the OSI model, ports and protocols, and IPv4 subnetting
Network implementation, including switching, VLANs and routing
Network operations, including monitoring and disaster recovery
Network security, including AAA, common attacks and defenses
Troubleshooting, the heaviest domain at 24%

Who it suits

Candidates in the final days before an exam who need a quick structured pass through the objectives. Because it is a condensed review, use it alongside more detailed lessons rather than as a first introduction. The description also encourages answering questions aloud, which is a good habit whatever resource you choose.

About this course

CompTIA Network+ N10-009 — the entire exam in 2.5 hours, not 8.

Your exam is Monday. You started an eight-hour course three weeks ago and you're forty minutes in. The retake is $399. This is the whole test in one sitting.

All five domains, every testable objective, every exam trap — free, the night before you walk in. Every other "complete" Network+ course on YouTube runs four to eight hours. This is the active version of everything that's on the test, with zero filler and no textbook.

The N10-009 is 90 questions in 90 minutes, and you need 720 out of 900 to pass. Five domains, weighted unevenly — and this covers 100% of them:

✅ Domain 1 — Networking Concepts (23%): OSI model, ports & protocols, cloud models, network appliances, IPv4 subnetting, SDN vs SD-WAN
✅ Domain 2 — Network Implementation (20%): switching & VLANs, static vs dynamic routing, wireless standards & channels, physical installs & network services
✅ Domain 3 — Network Operations (19%): documentation & diagrams, availability & disaster recovery, monitoring, organizational security & hardening
✅ Domain 4 — Network Security (14%): CIA triad, AAA, RADIUS vs TACACS+, attacks (DoS/DDoS, on-path, ARP & DNS poisoning), defenses, 802.1X & ACLs
✅ Domain 5 — Network Troubleshooting (24%): the 7-step methodology, cabling & interface counters (CRC/runts/giants), services (STP, APIPA 169.254, gateway vs mask), performance (latency/jitter/loss), and the tools

How to use this video: don't just listen. When you're unsure, pause and say the answer out loud before the narrator does. Active recall is why people pass. Passive listening is why people pay the $399 retake.
