Welcome to our CCNA Enterprise Infrastructure v1.1 learning path. It is a collection of multiple courses covering all the network topics you need to know to pass the latest 200-301 CCNA exam successfully. Each course covers a specific technology, starting from the basics up to the level of understanding required for CCNA certification.
We focus on WHY
We start from the basics and focus on understanding the fundamentals behind every technology. We are already in the age of AI. Computers will become better and better at configuring network devices. That's why it is much more valuable to know why a technology has been introduced and why an enterprise organization would benefit from using it.
We start each topic by explaining why it matters in the networking domain - why it was introduced in the first place, and what problems it solves. We then explain how it works under the hood. Lastly, we demonstrate how to configure and verify the technology on Cisco devices.
Let's see an example with OSPF:
- WHY: Why do we need a dynamic link-state routing protocol instead of distance vector ones such as RIP and EIGRP?
- HOW: How does OSPF build a link-state database and calculate shortest paths using Dijkstra’s algorithm?
- WHAT: Configure OSPF on routers, check neighbor adjacencies, and verify route propagation.
What you'll learn
For me, as an instructor, using the WHY–HOW–WHAT model of teaching helps CCNA students tremendously:
- Think like an engineer, not just memorize: Understanding WHY provides the context to grasp a technology from a design and architectural perspective. It encourages logical and out-of-the-box thinking. You think and design, AI executes and implements.
- See the bigger picture: Understanding HOW each device, protocol, and link fits into the overall network, makes the technology more meaningful.
- Retain knowledge longer, because you have the context around it: By connecting concepts to real-world problems, you remember how and why things work, not just what commands to type.
- Get ready for the real world: Understanding both the design and practical side of technologies gives you the confidence to handle actual network environments, not just exams.
Skills you'll gain
Who is this for?
Perfect for beginners and IT professionals preparing for the Cisco CCNA certification. You don’t need prior networking experience — just curiosity and motivation to learn.
How the Learning Path works?
The learning path follows a logical order — starting with the basics and moving toward advanced enterprise topics. It includes several courses, as you can see in the left sidebar of the page.
Each course consists of multiple sections, each of which includes several lessons, lab examples, and quizzes, where you can test your progress. The following diagram illustrates the learning path structure.
The goal is not just passing the exam, but understanding the technology behind it. You’ll see how protocols interact, how to identify problems quickly, and how to design reliable networks that scale. You’ll apply every concept through real device configurations and review questions that simulate CCNA exam challenges.
Outcomes
After completing this path, you’ll have the knowledge and hands-on skills to build, configure, and troubleshoot enterprise networks. You’ll understand how routers and switches work together, how IP addressing drives communication, and how to secure and automate your network. You’ll be fully ready for the Cisco CCNA certification and confident to take on real-world projects.
