The original post is gone, so I can't take a look. But I have to at least state that this seems like another case of a perfectly good question that mentioned a particular trigger word (education) and was therefore put on hold.
Of course there is no way to tell for sure without seeing the original post. But I do want to speak to this point made by Ron:
The problem with those type of questions is that the course material may not agree with what happens in the real world
I'm of the mentality that this is not our problem. If an instructor or education curriculum teaches something that doesn't match up to reality, that is their problem, not ours. We should always (continue to) answer questions from the perspective of reality.
To that end, I don't believe we should exclude education questions. Maybe the obvious "copy paste do my homework for me", but well though out questions, or questions from a student asking for clarification or further understanding should be welcomed. They are, after all, network engineers in training.... who will become network engineers, and hopefully remember a good experience when they interacted with the Network Engineering Stack Exchange. AKA, they are the future posters and responders.
