Even if someone knows, they are not allowed to tell you. When you start the exam, you have to accept an NDA that forbids you from discussing the exam contents with other people.
Do take a look at the "Skills Measured" section in the exam description page. Note that NETSH is not mentioned at all, at least explicitly (although it can be used to achieve some of the results listed there). The notes for the Skills Measured
say that the topics "include but are not limited to..." the types of skills listed, so in theory anything whatever could be asked in the exam. But in practice, you can expect the questions to be a reasonable match for the list of topics described in
the Skills Measured.
