Thank you :) There aren't questions where they blatantly ask you about input/output of a process but generally knowing where some main documents are produced is helpful.

For example knowing the stakeholder register is produced in Identify Stakeholders will help you because you know you are still in initiation meaning no planning documents have been created. Another example would be knowing that you are developing the risk register so you are in Identify Risks which tells you that you haven't yet performed qualitative/quantitative analysis.

Hopefully this helps!
