  • Robert Herron (5/5) : Mr. Bombal is just one of the best at what he does.
  • Akhil NR (5/5) : This is the one of the best course that i have ever attended online.
  • Christopher Moss (5/5) : Excellent course for anyone looking to gain python skills for networking!
  • Stephendeb Butler (5/5) : David is an excellent teacher and presents the course content in a structured manner.


  • Kom Phatak (1/5) : I am not sure whether the lab setup would work even after purchasing CML as Network Automation container facility is not there in CML labs.
  • Nathaniel Draper (1/5) : Without VIRL images you are basically left behind and nothing makes sense.
  • Kom Phatak (1/5) : Wasted a lot of time with VMware and GNS3 lab setup.
  • Eric Meinders (1/5) : I spent 2 weeks downloading different VMs, trying to get GNS3 to work (or just to recognize the various VMs), then trying EVE-NG which took 2 days to just get set up and inevitably failed because of the images.
