Free CCNA 200-301 Course: Network Fundamentals (Udemy.com)

This is a free, 80-minute introduction to networking fundamentals from David Bombal, built around the CCNA 200-301 and CompTIA Network+ exams. Eleven lectures in a single section walk through hubs, bridges, switches, routers, and port numbers, the vocabulary you need before real exam prep starts. It sits next to a full paid CCNA 200-301 course in our IT Certifications list, and that context matters: this is the on-ramp, not the destination. Complete beginners with just a computer and curiosity are the real audience.

Reviewers, many of them brand new to networking, praise Bombal for explaining switches and routers in plain language and keeping the pace friendly rather than technical. Several call him one of the better teachers they have found on Udemy. The complaints are about scope, not delivery: one reviewer found the tone almost too simple for an adult audience, and another called it an incomplete course, since 80 minutes barely scratches what a real certification course needs to cover.

There is no financial risk since the course is free, but it has not been touched since January 2023, so treat it as an orientation rather than an exam-ready resource. If fundamentals are still fuzzy, it is a solid warm-up before tackling the full Cisco CCNA 200-301 guide it sits beside on our list. If a hub versus a switch already makes sense, skip straight to a longer course that actually prepares for the exam.
