I really appreciate this website. I'm making a career switch from Telecommunications to a potential IT role at a NOC. The job posting said they're willing to train. But I want to do everything in my power to close that knowledge gap before the first interview. This website is my answer and savior. Thank you so much. Good quality content.

learned new things about switches and interfaces. great courses. any advice you can give me to start my network career and where i can train for CCNA?
Connected Dots Online9 months ago
Hi Labs, you can follow all the courses on this site to get started. Even though the content on the site does not yet fully cover everything required to pass the CCNA, it is a good start to get an in-depth understanding of the topics that are covered. I would recommend following all the courses on the site and using a book to cover the content that is not covered here yet. The courses on this site are a good complement to visually understand the concepts covered in books. Hope that helps!

I have had an issue where I completed the assigned task (answered the question correctly) during the "Cisco Switch CLI - Exercises" and the system would not move forward until I clicked on the hint and then answer. I have saved a screenshot if you need it. Otherwise this is an amazing learning resource. Thank you for all of your hard work!
Connected Dots Online11 months ago
Hi David, thanks for the feedback, and the heads-up regarding the issue you faced. If you could please email the screenshot to we will look into it right away! Thanks again for the heads up!

Sent. Thanks for the quick response.

We are working on an update to the lesson "Introduction to Cisco Switch CLI" as per Billy's suggestion below. We have already incorporated one "Activity Break" into the lesson and are working on incorporating 2 more of these. This should be ready in a day or 2. We will advise when the update is complete.
Billy11 months ago
That's awesome, thanks! I will definitely revisit that one in the future then.
Connected Dots Online11 months ago
Update: Activity Breaks 2 and 3 has been added to this lesson. We are working on one more.
Billy11 months ago
I've been taking these courses and enjoying them. Thanks for this resource! My one bit of feedback so far, I think it would be beneficial if in the "Intro to Cisco Switch CLI" there was a bit more of an interactive flow to it. Having a few boxes where it's explained and then you follow it up by doing it as well yourself would help to cement that knowledge. By the time I got to the exercise section I was scrambling through my notes and forgetting a lot of what I had just read.
Connected Dots Online11 months ago
Hi Billy. Thanks for the feedback. That is extremely useful feedback. We will modify that particular lesson to incorporate your suggestions. Please keep the feedback coming!

It would be good to be able to pick up where I left off when I resume a lesson. As it is now I have to scroll through previously completed sections.
Connected Dots Online12 months ago
Thanks for the feedback, Ric! This is already being incorporated into some of the newer lessons. It will be incorporated into the older lesson content over time.
