Best Online Course to Learn Computer Networking for CCNA Prep

If you’re considering a career in IT and wondering where to start, understanding computer networking is the first crucial step. Whether you’re looking to become a network engineer or just want to pass the Cisco CCNA exam, you’ve probably searched for the best online course to learn computer networking. The answer, for many beginners and aspiring IT professionals, has been a standout course on Udemy: The Complete Networking Fundamentals Course by David Bombal.

Why Learn Computer Networking?

Networking is the backbone of modern IT infrastructure. Without networks, there is no cloud, no internet, and certainly no business operations. Whether you’re just getting started or planning to earn your Cisco CCNA certification, networking is an essential skill.

Fortunately, in the age of e-learning platforms like Udemy, you don’t need to enroll in a four-year degree or attend costly in-person classes. Instead, you can take a well-structured and affordable online course to build the skills that matter. That’s where the Complete Networking Fundamentals Course shines.

Course Snapshot

Here’s what the Complete Networking Fundamentals Course offers at a glance:

• Over 24.5 hours of engaging video lectures
• 146 lessons covering everything from TCP/IP to network devices
• Hands-on labs and practical real-world demonstrations
• Quizzes and downloadable content for ongoing review
• A certificate of completion from Udemy

Perfect for Beginners Preparing for the CCNA Exam

One of the standout features is how this course aligns with the Cisco CCNA 200-301 exam. Built specifically with beginners in mind, the course breaks down difficult networking principles into easy-to-follow modules. This makes it one of the best CCNA prep courses online for someone just getting started.

Here are some key topics covered:

• How networks work and the OSI model
• IP addressing and subnetting
• Routing Protocols like RIP and OSPF
• Wireless technologies and network security basics
• Switches, routers, and real lab examples using simulators like Packet Tracer

Instructor David Bombal is a veteran in the networking world, known for his clear, concise teaching. Thousands of students have praised how he deconstructs complex topics like BGP—one user on Class Central noted that the clarity of explanations helped them finally understand IP addressing after months of confusion (source).

Affordable and High-Value

If cost is a concern (and let’s be real, most of us are budget-conscious), this course is hard to beat. While the full price is listed at $69.99, it’s almost always on sale for just $14.99. For less than the price of a pizza, you get lifetime access to an in-depth networking foundation that could launch your IT career.

Compare that to months of a subscription on LinkedIn Learning ($39.99/month) or CBT Nuggets ($59+/month), and the value is easy to see. Plus, Udemy offers a 30-day money-back guarantee, so it’s essentially a risk-free investment.

Pros

• No previous experience needed—beginner-friendly
• Real-world labs for hands-on learning
• Clear video guidance from an industry expert
• Lifelong access and self-paced format
• Great value for CCNA preparation

Cons

• The course focuses on fundamentals—intermediate learners may find it basic
• Simulators used in labs (like Packet Tracer) are not included and must be downloaded separately
• Some topics, while explained well, may require external study or resources for deeper understanding

Is It Really Worth It?

Short answer: Yes—if you are a beginner or looking to prep for the CCNA certification without spending thousands. Multiple reviews from platforms like Udemy and Class Central have highlighted how much clearer networking concepts became after taking this course.

However, as with any skill, one course isn’t a silver bullet. To truly master networking, you’ll need to supplement your knowledge with hands-on experience, maybe try simulation software like Cisco Packet Tracer or GNS3, and work with actual devices if possible. But as a launchpad, this course sets a strong foundation.

Here’s what some students had to say in their reviews:

• “David Bombal made networking click for me. The labs are excellent and easy to follow.”
• “I had no prior IT background, and now I feel confident enough to go for my CCNA.”
• “You probably can find this info online, but having it all organized and explained is SO worth paying for.”

Moreover, a ResetEra user mentioned that paying for the course gave them the motivation to stick with it—crediting the paid nature of the course itself as a motivational factor, especially given Udemy’s refund policy (source).

Whether you’re starting fresh, transitioning into IT, or prepping for the CCNA, the Complete Networking Fundamentals Course offers an unbeatable combination of quality instruction, actionable labs, and affordability. With David Bombal as your guide, you’ll likely walk away with not just theoretical knowledge, but practical tools that will help you succeed.
