Shubho:
There are very few questions on the PMP exam that directly ask "What is an output of" some process. All of ones that I experienced (back in 2019) were indirect and scenario-based. For example, the scenario description would lead you to a process, and then ask something along the lines of:
1) What information do you need to continue (an input)? or
2) How you would go about doing something (a tool/technique)? or,
3) What is the resulting document or action (an output)?
From that perspective, it is very much best to UNDERSTAND THE INTERCONNECTIONS of the ITTOs with the various processes in the PMBOK as opposed to memorizing specific ITTOs for all the processes.
Best of luck!
