The instructor had focus on both theoretical vs practical knowlede. On multiple occasions, the instructor made us pay particular attention to some details where it is easy to get confused and fail at configuring the feature correctly. This is immensely valuable for me when trying to establish a private lab built upon similar features, and also deep dive into our infrastructure. Also, when we have the opportunity to choose between different strategies, we made made aware of pros and cons or where administrators can apply different configuration strategies. The instructor showed deep practical knowledge when lecturing all subjects.
