To find out the time taken by the exam, you can register for the exam on the Prometric web site and see how much time you are allocated. You can cancel the registration process before you complete it. Typically, you will find out that you get somewhere around
3 or 4 hours, but some of that time is dedicated to the initial acceptance of the conditions and the period for entering comments at the end, so the actual time available for answering questions is less than the total exam time.
As to the number of questions in the exam, we are not allowed to tell. When you take the exam you have to accept an NDA that prevents you from revealing anything about the contents of the exam, so anyone that takes the exam cannot legally tell you the number
of questions.
