FAQ

I didn’t start doing this for money, I did it because I enjoy it. I realized I enjoyed it when I was training Skillbridge interns. The challenge wasn’t explaining networking. It was building labs that made them think and actually understand what was happening. It was the teaching by doing in an effort to take their understanding beyond basic theory.

I don’t have interns anymore, but I still build. It’s kind of a hobby, now. If no one’s using the labs, there’s no point.

Also, I want training to be accessible and frictionless.

No! These labs take real time to design and build. I take pride in the work and hold the quality to the same standard as if they were paid. See next answer.

I have had individuals find mistakes. I am only human. PLEASE PLEASE PLEASE let me know, publicly or privately, if you encountered or suspect an issue with any of my labs. Do not hesitate to call me out. I promise I won’t be mad. I am very responsive when it comes to this. Either it was a genuine mistake and I will quickly correct it, or I will explain why it wasn’t. WIN/WIN!

For those who have messaged me, Thank you!

I have had people ask for this so it is something that I will be working on implementing in the very near future. Today’s date is June 22, 2026. 🙂

Full walkthroughs (video and/or PDF) take longer to create than the labs themselves. Quick answers give you something to check your work until the full explanation is published.

No schedule, though I try to release weekly or biweekly. CCNA, CCNP. Whatever I’m focused on at the moment is what gets built.

Stay informed by subscribing on the lab pages or following on Facebook. You’ll only receive emails about lab releases or updates. That includes new labs and publishing of walkthrough videos or PDFs.

Not every lab release triggers an email. Updates are grouped so you’re not getting spammed. The following are the different email list I have.

  • CCNA Fundamentals Troubleshooting list
  • CCNA Troubleshooting list
  • CCNP Troubleshooting list
  • CCNP Training list
