Computer Networking and CCNA 200-301 Prep
Learn computer networking from the ground up and prepare for Cisco's CCNA 200-301 exam: the OSI and TCP/IP models, Ethernet switching, IPv4 addressing and subnetting, VLANs and trunks, spanning tree, static routing and OSPF, IPv6, DHCP, DNS and NAT, ACLs and security basics, wireless, and network automation, with Packet Tracer labs throughout. Exam preparation only: the EDWartens certificate is not Cisco's CCNA, which is earned only by passing Cisco's 200-301 exam.

Project
The course project
Optional practice that ends in the kind of job the course prepares you for, with the documents that go with it.
About 12 hours
Designing and building a segmented office and plant network for a juice bottling site in Packet Tracer
Design the network for a juice bottling plant with an office, a filling and packing hall and CCTV. Then build and test it in Cisco Packet Tracer. You plan zones in the lab, write a VLSM address plan, and build VLANs, trunks and Rapid PVST+ with a chosen root. You add inter-VLAN routing on a multilayer switch, OSPF to the edge router, PAT, DHCP, SSH and an ACL that lets the office read the plant historian and nothing else. The sample pack shows each document for a plant in Chile.

Practise what you learn in the free 3D lab
Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.
- Practise safely, so a mistake costs nothing.
- The lab checks your work like a site test, so you know when it is right.
- Free, in your browser, with nothing to install.
Why learn with EDWartens
What you get with this course.
- Free from the first lesson to the final assessment.
- Practice in a free 3D lab in your browser, with nothing to install.

FAQ
Common questions
Is this the CCNA certification?
No. This is an exam preparation course. The EDWartens certificate shows you completed it; the CCNA is awarded only by Cisco, to people who pass Cisco's 200-301 exam, which you book through Cisco. EDWartens is not affiliated with Cisco, and Cisco, CCNA and Packet Tracer are Cisco trademarks.
Which version of the CCNA exam does it follow?
The v1.1 exam topics, which is the version on sale now. Cisco has announced that v1.1 can be taken until 2 February 2027 and that v2.0 goes live on 3 February 2027 under the same code. The notes list what v2.0 adds, and most of the course carries straight into it. Check Cisco's site for the current exam before you book.
Who is the Computer Networking and CCNA 200-301 Prep course for?
IT and OT technicians, students and anyone new to networking, including people who look after plant networks and want to understand the IP networking under industrial protocols. No experience is needed.
Do I need routers and switches?
No. Every lab runs in Cisco Packet Tracer, which is free with a Cisco Networking Academy account. The notes show where to download it.
Whose lessons are these?
Most are from Jeremy's IT Lab's free CCNA course, with short lessons from freeCodeCamp.org, David Bombal and PowerCert Animated Videos, credited on every module. EDWartens wrote the notes, the worked subnetting problems, the practice tasks, the 169 practice questions, the project and the final assessment.
Is the Computer Networking and CCNA 200-301 Prep course really free?
Yes. Every module, the notes, the project and the final assessment. The only paid item is the EDWartens certificate, if you want it. Cisco's exam is separate and is paid to Cisco.
How long does the Computer Networking and CCNA 200-301 Prep course take?
About 17 hours of video plus notes and practice, plus about 12 hours if you do the project. Most people need extra lab and revision time on top before sitting Cisco's exam.
What is the project in the Computer Networking and CCNA 200-301 Prep course?
You design and build the network for a juice bottling plant in Rancagua, Chile, in Packet Tracer: a VLSM address plan, VLANs and trunks, spanning tree, OSPF, PAT, DHCP and an ACL that keeps the office out of the control network, then test it and write the handover documents. A complete sample pack shows each one.
Do I have to use the lab?
No. The lab is optional practice. You can skip it whenever you like, and it never blocks your progress, the final assessment or your certificate.
Is the lab free?
Yes. Every lab level for this course opens in your browser, free, with nothing to install.
Is the Computer Networking and CCNA 200-301 Prep course free in India, and what does the certificate cost?
Yes. Learning costs ₹0 in India: every module, the written notes, the practice tasks and the final assessment, with no card and no trial period. The only paid item is the optional EDWartens Certificate of Completion, ₹499 including GST for this beginner course, paid in rupees through Razorpay, and only if you want it after passing the final assessment.

The full list with minutes is under "What you learn" on this page.
What can I do after the Computer Networking and CCNA 200-301 Prep course?
After the Computer Networking and CCNA 200-301 Prep course: Explain the OSI and TCP/IP models and encapsulation, and choose copper or fibre for a link; Configure Cisco routers and switches from the command line in Packet Tracer, and secure and save them; Predict how a switch learns MAC addresses and how ARP finds a host. These are the practical outcomes the course is written around, and the final assessment of 15 questions checks them.
What software and hardware do I need for the Computer Networking and CCNA 200-301 Prep course, and does it cost anything?
