The Drag-n-Drop questions on the real exam do require an accurate answer. However, there are often several ways to create a correct answer; that is several ways of organizing the boxes that make a correct answer.
The DnD questions were difficult to create because we had to record *every* correct answer, but these types of questions also raise the "level" of the exam from pure memorization to a level that is more about testing whether or not you know what "code" (be it Java, JSP, or JSTL) is needed to solve a particular problem.
