This free online course teaches you everything you need to know to pass the CCENT exam.


About this course

This course covers everything you will need to pass the Cisco CCENT 100-101 ICND1 exam, but it also provides many information about internetworking in general. The Cisco Certified Entry Networking Technician (CCENT) certification is a famous IT certification from a company called Cisco. After you pass the ICND1 exam, you will need to pass ICND2 200-101 exam to obtain your CCNA certification.


This tutorial is designed for people studying for the CCENT ICND1 100-101 exam, but it can also be used by anyone who wants to learn about computer networks in general.


You should have a basic understanding of computers. You should have some basic knowledge of system administration (configuring IP addresses, connecting to the Internet, installing Windows, etc.). An experience with the command line is recommended, but not required.

What you’ll learn

You will learn what computer networks are, the difference between the OSI and TCP models, what an IP address is, how to configure an IP address on a Cisco router, etc. In later lessons we will go through topics such as routing protocols, IPv6, NAT, Spanning Tree Protocol…

  7. the content matches what I learned in university network course


    I accidentally found this website when I was preparing for the final exam of my university network security course. When the university exam passed, I am aware this web content is very helpful for me to prepare for CCENT exams. And it did help me learned comprehensive knowledge on network basics. The content structure resonates with what I learned in university lecturers. I am very grateful for the instructor TUNA PEYO.
    Thank you guys very much.

    Great learning👍 very good content, explanation was very good in a simple manner. I recommend everyone who like networking go fir this course.

  16. Good Information


    A lot of good information. Some topics covered I don’t think are in ICND 1 though like EIGRP and VTP I believe aren’t until ICND 2, if you are taking the Cisco Exams. Also this course will be difficult I think if you have no experience at all in networking but if you are studying for the CCENT or CCNA and are looking for additional study material it is helpful.
