Hi,
here
you can find official info regarding the 10-min break recently introduced in the PMI exam:
Both the online proctored testing and center-based testing option for the PMP exam will now have a built-in 10-minute break. You do not need to take the entire 10 minutes, but are more than welcome to. The exam is now divided into two parts. You will start the break once you review and submit the first part of the exam. Please note, you will NOT be able to review questions from the first part of the exam after you submit it and start your break.
You will be permitted to leave the room during the break. Once your 10-minute break is over, your proctor will check you back in and you will finish the second and final part of your exam. If you do not return to the room at the conclusion of your 10-minute break, your exam session will be terminated.

For PMP [and PMI-PBA], there is a built-in 10-minute break that will appear after you complete the first exam section (between 85 – 100 question). Once you finish the section you will be able to review all of your responses prior to entering your break. Please note, once your 10-minute break is over, you will not be able to return to the questions from the first section of the exam. Once your 10-minute break is over, your proctor will check you back in and you will finish the second and final part of your exam. If you do not return to the room at the conclusion of your 10-minute break, your exam session will be terminated. You will not be permitted to take any additional breaks during the exam for any reason and leaving your desk will invalidate your score.
As you can see, PearsonVUE mentions that the break is between question #85 and #100, which may explain the confusion about how many questions are included in the first part. When I took the exam the first part was about 89-90 questions; I was sure it was 90, but based on other comments I thought maybe I remember it wrong and it was 89. Anyway, you will be clearly prompted when the first part is over, and will be asked to confirm twice that you are ready to submit the first part after review.
Please, notice that there is no time limit for each of the two parts. You will be given 4 hours for the whole exam; it will be up to you to manage this time between the two parts. Whatever time is left after you submit the first part, that will be given to complete the second part.
I would say the break is not mandatory (meaning that you can decide to skip it), but this does not mean that if you decide to skip it you will be given 4 h for 200 questions, with the option to review all of them at the end. In fact, the exam is still composed of two parts; once you submit the first part, you can choose whether you want to take the break, or if you prefer to skip it and are ready to move to the second part of the exam.
Hope this helps clarify how the break works,
Gabriella
