The PMBOK Exam Domains and Process Groups. The PMP Domains spell out exactly what you will be tested on, as the exam covers a broader set of skills than what is in the PMBOK Guide. There are five domains: initiating, planning, executing, monitoring, and closing. A domain is an area, the topic, the discipline that you will be tested on in the PMP Exam. There are specific activities that you need to know how to do in order to pass the exam. Initiate the project – PMP Domain I. Plan the project – PMP Domain II.
