Fantastic CCIE Data Center training!

NIL’s CCIE Data Center Preparation Workshop is a fantastic course! With our instructor’s help, we practiced designing/troubleshooting with all of the most relevant and expansive CCIE Data Center technologies.

Mitja Robas is the best teacher I ever known: he has a lot of hands-on experience that coordinates perfectly with [the student’s] knowledge, producing a very successful training session.

I’m very satisfied with this course for all these reasons—plus, we were able to use all the labs also during the weekend. Amazing!
