After all, in my second try I followed the advice: I counted the number of neurons in the 1st layer, which was 4, and the number of training samples, which was 2, so the dimension of Z[1] should be (4,2).

Hey @Matthias_Kleine,
In this question x1 and x2 represents the input neurons, and not the number of examples. So, the statement that the network is fed with 2 examples is incorrect. I hope this resolves your query, and will help you select the correct answer.
