CompTIA Network+ (N10-009) Full Course & Practice Exam (Udemy.com)
CompTIA Network+ (N10-009) Bootcamp - Certification preparation course on the most popular networking certification!
Created by: Jason Dion
Last updated September 2026
Our take
Based on the ratings of 42,085 students, a sample of their written reviews and the syllabus, as the course stood in September 2026. No course pays to be reviewed.
This is Jason Dion's prep course for the CompTIA Network+ N10-009 exam, built around 32.8 hours of video across 30 sections, a study guide, 28 quizzes, and a full practice exam. It walks through all five exam domains, from the OSI model and IP addressing to network security and troubleshooting methodology. The course is billed as beginner level, but the requirements list expects some prior exposure to networking basics, so it suits people already working help desk or support roles who want the certification, not someone who has never touched a router.
Reviewers who passed the exam credit the course directly, several posting their scores and thanking Dion's explanations for getting them through. One reviewer, whose first language isn't English, says the teaching style made dense material click. A recurring complaint is that the practice tests quiz on material the video lectures never actually cover, forcing extra outside study; multiple reviewers raise this. Others found the pace fast or the explanations too dense, and one reviewer called the course thin on harder topics like encryption and PKI and ended up supplementing with a textbook.
At 42,085 reviews and a 4.7 average, with a bestseller badge in its category, this is the default pick for Network+ candidates, and it was refreshed in September 2026. It is not the leanest option; one reviewer points to Andrew Ramdayal's course as tighter and more exam-focused. But the volume of content and the included practice exam make this a solid single source, as long as learners are willing to fill gaps with outside notes on the trickier security topics.
Pros
- Thousands of reviewers report passing the real exam after taking it
- Covers all five N10-009 domains across 259 lectures plus a full practice exam
- Dion's explanations praised even by a non-native English speaker
- Refreshed September 2026, so content tracks the current exam version
Cons
- Several reviewers say practice tests cover material the lectures skip
- Fast pace and dense wording make some sections hard to digest
- Thin on tougher topics like encryption and PKI, per a reviewer
Listed as beginner, but reviews and requirements point to learners with some hands-on IT support experience already.

By Kuo-Chang Chu on 9/7/2026
Sept 7th 2026, I pass with 775 points. This time I got lots of subnettings: 1 in PBQ and 3 or 4 in the questions exams. One of the questions about subnetting was: Company A was merging with Company B and Company B was having 1 Public address ( starting with 10.x.x.x ) 2 Class C Address ( 192.x.x.x ) . The manager wants to merge into One big Class B Address. I didn't have a clue how to procceed. Other sections that appeared very often was the Troubleshooting methodology x 3 or 4 questions ; and the Cloud IaaS/Paas / x 3 or 4 questions. Also, there are lots of configurations images interpretations ( in other words: what should appear in your screen either for Linux / Windows / Switch / Routers ) , if you don't know what the alphanumeric numbers mean, you won't be able to answer the questions. So, I strongly recommend hands-on lab experiences. I won't write here which labs are cheaper or convenient, to avoid conflict of interest.

I just passed the CompTIA Network+ exam, and it only took me about a month and a half of studying! This course covers everything you need to know for the CompTIA Network+ exam. Jason Dion explains the concepts clearly and makes even the more difficult topics easy to understand. I personally learned and understood much more from Jason Dion's course than I did from the official CompTIA course. I also highly recommend Practice Exams Set 1—they're an excellent way to prepare for the real exam and helped me build confidence before test day. If you need even more practice, Practice Exams Set 2 is also worth getting. Each set has 540 questions One study tip that really helped me was to spend more time on practice questions than watching videos: 30% videos → Review topics you consistently miss. 70% practice questions → Build exam-taking skills, identify weak areas, and reinforce what you've learned. I also recommend consistently scoring 75% or higher on the practice exams before scheduling your Network+ exam. While no practice score can guarantee a passing result, consistently reaching that range is a good indicator that you're on the right track. I only say that because I personally and other people found that Jason Dion's test is tend to be harder than the real exam. I highly recommend this course to anyone preparing for the CompTIA Network+ certification. It was one of the biggest reasons I was able to pass.
By Nathaniel Adam Calderon on 8/2/2026
I took the 6 sets of Practice Exams and reviewed the missing objectives by using the search tool and inputting my specific OBJ number that I needed help with. I got a 770, which is barely passing, but I studied hardcore for about 6 hours every day using a pomodoro timer to take breaks. I did use the CompTIA CertMaster Labs and Study material, but I didn't review the study material and only followed along when my professor gave a 4-hour lecture in the prep course I took. If I were to do it again, I would watch these videos while taking notes, study Acronym flashcards, and do the CompTIA CertMaster Labs (only to help with practical Application). I also would learn the Subnet cheat sheet table, and overall try to understand all the concepts in the big picture in Networking. I hope it goes well for you. Study hard and do not give up!
By Marcin Marzejon on 7/8/2026
This course was amazing and helped me pass my Network plus exam on 7th July 2026 with a 90% score. The test and additional 2 sets of 6 test are definitely very helpful. The only thing i would suggest is to improve the practical questions as on the real exam they are completely different (more interactive, using command line etc)
By Jaime Eduardo Ximenes Soares on 6/23/2026
The course offers a comprehensive understanding of each topic and domain, with clear explanations that make complex concepts easy for students to grasp. Each section includes short quizzes to reinforce learning, and a full practice exam at the end provides an experience closely aligned with the actual certification test. This structured approach makes the course highly effective and is strongly recommended for anyone preparing to earn their certificate.
By Jaemy Malik on 5/8/2026
Goes on a deep dive on topics, but knowing myself I wouldn't get it the first time of watching, on my 2nd rewatch Im gonna take down some notes after taking all the practice exams and testing where I am in terms of knowledge. I most likely will watch this a 3rd time, just to let everything I learned sink in.
By Mathebula Tiyiselani Ashley on 5/5/2026
My experience learning Computer Networking on Udemy was very positive and rewarding. The platform made it easy to understand networking concepts through simple explanations and practical examples. The video lessons were clear, well-structured, and beginner-friendly, which helped build confidence step by step. One of the best things about studying on Udemy was the flexibility. I could learn at my own pace, revisit difficult topics, and practice whenever I had time. The instructors explained complex topics such as subnetting, routing, switching, and troubleshooting in an easy-to-understand manner. The practical demonstrations and quizzes also helped improve my understanding of real-world networking environments. The course content was organized professionally and aligned well with the CompTIA Network+ objectives. Another positive aspect was affordability. Udemy courses are often available at discounted prices, making quality IT education accessible and cost-effective. Overall, the learning experience was excellent, informative, and highly beneficial for building networking knowledge and preparing for an IT career.

I just passed my CompTIA Network+ exam, and a huge part of my success came from Jason Dion’s course. The material was clear, well-structured, and focused on exactly what you need to know for the exam. I especially appreciated how diagrams were used in the video. One trick I learnt closer to the end of the course was that I could pair this with some practice questions from ExamCompass. Dion’s course was definitely the foundation of my preparation. If you’re studying for Network+, I highly recommend this course. It helped me go into the exam feeling confident and prepared. Thanks again, Jason!
By Michael Weathers on 3/14/2026
I went through a different Network+ course and at the end, I still felt under prepared. So I got this course, and it was so much better even though I only had about 2 weeks to get through the entire 33 hours of video, I felt so much better about going into the exam. I passed my exam on March 11. Thank you to the creators and instructors for doing such a good and thorough job of covering all the exam objectives. I would recommend this course for anyone who is planning on taking the Netowrk+. Very well made!
By Vasilii Baterianu on 2/11/2026
Thanks so much, JD and team, for updating and creating that course! For me, like a totally new person in the industry, that was super helpful, and I don't think it's doable to pass N+ without that course! Especially, practice exams (sold extra but from same universe) help a LOT! it's 90 Qs for 90 mins and usually much harder than on exam itself (70 for 90 mins with ~5 PBQs) Sincere gratitude for this journey, and truly appreciate ALL effort behind the scenes actions to make this course ideal to pass N+! Thank you!
