When I finished for the Course list, I can test CCNA, That's right?
Connected Dots Online8 months ago
Hi Trân, this course list is a good beginning to get started on learning networking. As it stands currently, it does not cover everything that will be tested on the CCNA exam. Over the next few months we will be adding more courses to the course list that will cover the rest of the material that is tested on the CCNA exam.

is this addition done?
Connected Dots Online5 months ago
Hi Jagbir, we will not be adding an online CCNA exam. We will keep adding content to help learn and practice the content covered on the CCNA exam.

is the available content enough to crack CCNA exam
Connected Dots Online5 months ago
Hi Jagbir,
The content covered in this particular course should be sufficient to pass the subnetting portion of the CCNA exam. However, courses to cover other topics on the CCNA exam such as OSPF, RIP, IP Services, TCP/UDP are still under development.

This is without a doubt the best interactive network training material. The methodoloy to teach is so simplistic yet interactive that even newbies can grasp the complicated concepts. There are plenty of examples and exercises to make sure you truly understand all concepts.

Thank you very much for creating such an unique way of teaching Networking concepts.

in the 1st chapter, "Introduction To Number Systems", it says, "the hexadecimal system employs numbers 0-7 and letters A-F". Isn't it "0-9"? That said, thank you very much for the course - really helpful!

Thanks very much for pointing out that mistake, Dmitry! You are correct, it should read "0-9". It has been fixed now. Thank you for your feedback as well. It's great to hear that the content is helpful!
