Paid Udemy video courses include a certificate of completion when you finish; free courses and practice-test-only courses do not. It shows you did the work, but it is not an accredited qualification. For the Cisco or CompTIA credential itself you pass the certification provider's exam; the course certificate is not the certification.

-
- Low-star reviewers call it disjointed, with older clips and topics that pop up out of order

5
Introduction to networking for complete beginners (2026)
A free, under-two-hour first look at IP addresses, firewalls, ping and traceroute, meant as a warm-up before CCNA or MTA study rather than a course in itself.
Best for: Total beginners who want a quick, plain-English first look at networking before starting CCNA or MTA.
-
- Explanations that reviewers call clear, direct and easy to digest for beginners
- Covers ipconfig, ping and traceroute, so there is something to try on a real PC
- Short enough to finish in one sitting, with a clear path on to MTA or CCNA

-
- High level, and one 2-star reviewer wanted more definitions and examples
- One reviewer says it leans on older products, another wanted livelier delivery and animations
- No certificate and only two quizzes, so there is little to practise with
6
