Hi Robert,
thank you for your kind words and for the response.
Here my thoughts:

.... That being said, it makes sense to me that the project manager will not always be the subject matter expert for every task and activity that encompasses a project.
For instance, if I'm the project manager working for an innovative and specialized technology project, chances are I'm not going to be the subject matter expert on all the mechanisms within the project. As the project manager, I must consult with my firmware, software, and development experts so I can create a robust project scope statement and develop a realistic schedule, budget, risk register, etc. Project managers often confer the expertise of their team so they can plan accordingly.
Well, i know that the project manager is not allway the subject matter expert for everything hapening at his/her project. This wouldn't work in real life.

I am a project manager in the IT Industry for several years now and also dealing with the PMBOK Guide knowledge since a few years (just didn't the exam yet, but this will happen in a few weeks now).
It is totally clear to me, that the project manager is not the expert for everything and therefore he/she had the project team and other experts arround.
But in the end he/she is responsible for all the results and everything what is happening while the project.
In my experience sometimes it could be even counter productive, if the project manager (may be recruited out of the available experts) is the best subject matter expert in his project ...

In any case, I understand your frustration and I can see how you might have misinterpreted the question to be asking for the person or party responsible for the project's process results. Please let me know if you have any other questions or concerns regarding this and I will do my best to clarify.
First of all don't worry, i am not frustrated, not at all. It makes really fun to me to fresh up my PMP knowledge with the help of the pm prep cast and all the other stuff available here. You guys do a really great job here.
I am just a fan of precision (may because of my german background

).
And i am still convinced that i did not missinterprete the question.
From my sight of view the question is clearly asking for the responsibility and not for who is performing the determination ...
It asked:
Who is responsible for determining ...
it asked
not:
Who will conduct (do, perform, execute ...) the determination ...
Don't get me wrong; i do not want to be anoying and it is true, it is not reall THAT important regarding this specific question.
But it is more for instance and for making the point clear regarding what you allready mentioned, that it is really important to read the questions full and concentrated and precise and to get the right context of all of the questions.
I think the discussion could help therefore.
Best regards,
Markus
