What you should pay attention to is the best practice mentioned in the videos. There have been many questions where they have just asked about such details. They also asked what Dynatrace modules (One, Community, Support etc.) could be found on the Dynatrace website and in the DT console. There were certainly questions about the mind map.
In general, if you watch the videos 2-3 times with understanding and take notes, you should pass without a problem:)
