TOPIC: Why Agile or Scrum are not in the Select Criteria

I just ordered the PMP Exam simulator 2021, I am looking at the Timed/Learning Quiz Engine, under the select criteria, I don't find knowledge areas and Domains for Agile or Scrum, as those a big content for the exam. Can you explain why?

Hello. As I understand it, the Exam Simulator is aligned to the exam content outline. There are no Domains for Agile and Scrum. The PMP domains are People, Process, and Business Environment.
There's an article in the Help section here that might give you more guidance: pmhelpdesk.zendesk.com/hc/en-us/articles...ge-for-the-PMP-exam-

You'll find agile questions scattered throughout, just as you will in the real exam. Hope that helps.
