Network+ rewards people who can read a topology, do subnet arithmetic without panicking, and explain why a host cannot reach a server. Video alone will not get you there. You need one course, one question bank, and a console or simulator where you can break a small network and fix it. We make SecLern, so it is first on this list; the disclosure is here so you can discount the ranking and still use the rest of the page.
| Option | Best for | What it costs | Skip it if |
|---|---|---|---|
| SecLern | Console labs, subnet drills and exam simulation | Free tier; Pro $15/month or $99/year | You want one long video course |
| Professor Messer | A free first pass over every objective | Videos free; notes paid | You need graded configuration practice |
| Dion Training | Exam-feel questions with explanations | Paid per pack | You have not built a network yet |
| CompTIA CertMaster | Official Learn, Labs and Practice | Paid per exam | You are paying yourself |
| Total Seminars | A long, personality-led video course | $249 for N10-009 TotalVideo | You need reps more than lessons |
| Cisco Packet Tracer | Free visual network building | Free, account and install required | You need N10-009-mapped grading |
| ExamCompass | Free topic quizzes | Free | You need teaching explanations |
What N10-009 asks for
Network+ N10-009 is a maximum of 90 questions in 90 minutes, with multiple-choice and performance-based questions, and a pass mark of 720 on a 100 to 900 scale. The domains are networking concepts at 23%, implementation at 20%, operations at 19%, security at 14%, and troubleshooting at 24%. Troubleshooting is the heaviest single domain, which is why a resource that only teaches definitions is a poor fit.
The N10-009 exam page carries the current facts and the objective list. Check the IPv4 addressing objective on that page: if you cannot explain subnetting from the wording the exam uses, fix that before buying anything.
The short answer
Watch a free course to learn the vocabulary, drill questions daily, and spend real time in a console or simulator. The table compares the options on those three jobs, not on how many hours of video they contain.
1. SecLern: our pick for console labs and subnet drills
The N10-009 path holds 1,599 questions, 39 performance-based questions, 71 labs and 25 lessons. The labs are Cisco-style console tasks over a small topology: rebuild an uplink as a trunk, find where traffic to the warehouse stops, stop a rogue DHCP server, relay DHCP to a server on another subnet. You type commands and the lab grades the state you leave behind, not the words you choose.
The free tier gives you 30 study questions a day, three labs and unlimited flashcards. Pro is 15 dollars a month or 99 dollars a year, and the 29 dollar Exam Sprint covers 90 days. If subnetting is the weak spot, the free subnet calculator shows the working, and the subnetting guide teaches the block-size method. The labs hub lists each console task by name.
Good for: people who can watch a video and still freeze when asked to configure a trunk. Skip it if you want a single long course; we do not sell one, and the labs assume you have met the vocabulary somewhere else.
2. Professor Messer: the free course to start with
Messer's N10-009 course is 87 free videos, 12 hours and 55 minutes, in objective order. The videos are free; the 70-page course notes are a paid extra. It is a complete zero-cost explanation of the syllabus, and it is where most people should begin.
Good for: a first pass over every objective without spending money. Skip it if you learn by typing rather than watching; the course cannot tell you that your trunk is misconfigured.
3. Dion Training: exam-feel practice
Dion's N10-009 practice exam pack gives randomized question sets, unlimited attempts, detailed explanations and 12 months of access. It is a straightforward drill product: no labs, no simulator, just questions that feel like the exam and explanations you can read afterwards.
Good for: the last month, when you need volume and exam rhythm. Skip it if you have not built a network yet; questions about STP will not teach you what a blocked port looks like.
4. CompTIA CertMaster: the vendor's own materials
CertMaster Learn is the official e-learning with flashcards and performance-based questions. CompTIA Labs provides virtual environments with lab guides aligned to the objectives, and CertMaster Practice is the official knowledge assessment. CertMaster Perform bundles all three.
Good for: employer-funded study and anyone who wants the vendor's alignment. Skip it if you are paying yourself or studying for several certifications; it is licensed per exam and priced accordingly.
5. Total Seminars and Mike Meyers: the long course
Total Seminars sells the Network+ N10-009 TotalVideo course at 249 dollars: 20-plus hours taught by Mike Meyers, Joe Ramm and Lyndon Williams, mapped to all five domains. It is the most traditional option here and the most expensive single purchase.
Good for: long-form learners who want one course to cover the whole syllabus. Skip it if your budget is tight or you already know the material and need practice.
6. Cisco Packet Tracer: free and capable, with a caveat
Packet Tracer is free from Cisco, but you need a Cisco Networking Academy or Skills for All account, and you install it on Windows, macOS or Linux. It is genuinely good at building networks: drag devices, cable them, configure VLANs and routing, and watch packets move.
The caveat is alignment. Packet Tracer is a teaching simulator for Cisco courses, not a product mapped to N10-009. You will spend time on skills the exam does not test and miss CompTIA-specific phrasing. Use it to understand how a network behaves, not as your only exam resource.
Good for: free, visual, hands-on network building. Skip it if you want graded tasks that map to the objectives, or if you cannot install software on your machine.
7. ExamCompass: free topic quizzes
ExamCompass publishes free Network+ N10-009 quizzes by topic, from the OSI model to ports and wireless. They are short, browser-based and free.
Good for: a five-minute check on one objective. Skip it if you need explanations deep enough to teach; a topic quiz tells you that you are wrong, not why.
How we chose
We ranked on five jobs: explaining the objectives, drilling recall, subnetting practice, hands-on configuration, and exam simulation. Price and free tier were the tie-breakers. We checked every competitor fact on the vendor's own page on 28 October 2026 and linked it below. We did not include leaked question sets, and we did not include a course we could not verify was updated for N10-009.
One deliberate omission: we did not rank a bootcamp. The price and format vary too much to compare honestly in a table, and the good ones are usually employer-funded.
The subnetting problem, specifically
Most Network+ failures are not caused by a missing definition. They are caused by slow subnet maths under time pressure. A question that asks for the broadcast address of a /27 should take seconds, not a minute of scribbling.
Train it three ways. First, learn the block sizes: 128, 64, 32, 16, 8, 4, 2, 1. Second, do ten questions a day with a timer. Third, use the subnet calculator to check your answer, not to get the answer. The calculator is a marking tool; the exam does not have one.
What a console lab has to prove
A console lab is worth paying for only if it makes you prove something. "Configure a trunk" teaches a word; a lab should leave you at a prompt where the trunk output lists the interface, the allowed VLAN list and the native VLAN, and the grade reads that state rather than your clicks. Our labs grade the end state, and that is also the standard to hold every other platform to.
Four questions for any platform. Does the task name the objective it checks, or only the topic? Does it grade the state you leave behind, or the steps you took? Does it start from a broken network, or a clean one? And when you fail, does it explain the failure in terms of output you could have read? A platform that answers all four is a lab. One that answers two is a video with a terminal picture.
The broken-start question matters most on Network+. Troubleshooting is 24% of the exam, the heaviest single domain, and every troubleshooting item starts after something has already failed. Practising on a clean topology teaches configuration. Practising on a broken one teaches the exam.
Reading a topology in four passes
Most topology questions are decided before you configure anything, in how you read the diagram. Four passes, in this order.
First, endpoints: what talks to what, over which protocol and port, and which side started the conversation. Write it as a sentence, because direction decides both the ACL and the NAT rule. Second, the layer-2 boundary: find where the source's broadcast domain ends, and name the device and interface that ends it. Third, the layer-3 boundary: the first hop, the route out, and the point where the subnet changes. Fourth, the failure: place the symptom on the layer it belongs to. A host that reaches nobody usually has an addressing problem; a host that reaches everything except one server usually has a filter.
Only then touch a prompt, and read before you write: addresses, interface state, VLAN membership, routes. The N10-009 exam page names the objective behind each step, and the Network+ lab catalogue has a task for each one, most of them starting from a working network that has been broken somewhere.
What free actually buys you
Free is a real option here, and it is not the same as free forever. Messer's course plus ExamCompass covers explanation and quick checks at zero cost, and Packet Tracer costs nothing but an install and an account. What free does not give you is a grade on a task you designed badly, and that is exactly what a candidate needs in the last month.
So spend the zero-dollar weeks early, on vocabulary and on building small networks in Packet Tracer. Spend money, if you spend it at all, in the final month, when the scarce thing is feedback rather than content.
There is one exception worth paying for early: a subnet drill you can mark automatically. Subnetting is the only topic on this exam where speed is the skill, and speed comes from repetition with immediate correction, which is exactly what a calculator with a practice mode gives you for free.
A four-week stack that fits a job
Week one: Messer's concepts and implementation sections, 45 minutes a day, plus 15 subnet questions. Week two: operations and security, plus one console lab every second day. Week three: troubleshooting, the heaviest domain, with a lab every day. Week four: two timed sets, review, and one lab on anything you missed twice.
If you have no networking background, add a week at the front for cabling, ports and addressing, or follow the Network+ study plan instead of improvising. Network+ assumes you can read an IP address and know what a switch does; it does not assume you have configured one.
What to do this week
Download the objectives and rate your confidence per domain. Watch the Messer section for your weakest domain, then answer 20 questions on it the same day. Book one console lab. On the weekend, take a 45-question timed set and review every miss.
Book the exam when two fresh timed sets land above 80 percent and you can complete a trunk, a static route and a DHCP relay without notes. If you are deciding between certifications, read which to take first. Until then, more videos will feel productive and change nothing.
