Are you a customer of The PM PrepCast? If yes, then you can access the "self assessment" questions as part of the PrepCast in the LMS. Look into Modules 4-13 (if I remember the numbers correctly) where you will see a PDF with these questions. Mind you... they are not representative of the PMP exam though. They are only intended to test if you retained the knowledge presented by the training lessons.
Certain tasks from the exam outline were definitely included in the exam (e.g. inform stakeholders of approved project charter, conduct kick-off meeting or archive project documents) that really don't get covered in the PMBOK. Question scenarios that ask what to do next or what got missed sometimes included these tasks as possible answer choices. When evaluating the answer choices on the exam, knowing these tasks were considered an important part of Initiating, Planning, etc., sometimes helped in my selection of the best answer.
Perhaps others with recent exam experience can also weigh in with their take on the importance of the exam outline.
For me it was helpful to review and memorize the tasks of the PMI Exam Content Outline (not verbatim but the general gist of the task). The exam included questions that asked, "What should the PM do next?" or "What was likely not done in this situation?". Knowing the tasks helped with these types of questions.
