1.2.3.5. Position of wh-signs
There are three common configurations of content interrogatives: in the first one, the question sign occurs in its basic (i.e. in-situ) position, namely, if it questions the subject, the subject position, if it questions the object, the object position etc.

In the second configuration, a question sign occurs twice in the question (doubling): with one copy in the basic position and one copy in the question-final position, see [Syntax – 1.2.3.7].
In the third one, the question sign occurs in the sentence-final position.
