@Lawtonb Benjamin, thank you for watching the series and for asking. Really good question - unfortunately there aren't any other SailPoint resources that go further into depth regarding the exam questions.
Since the IdentityNow Professional Study Guide is the authoritative source for the exam structure, I'd recommend being able to answer questions from both of the perspectives you mentioned for 2.01 and 5.03 - going wider in scope, in case the questions get asked at either level. And similarly with the other objectives in the guide.
And if you run into an area where you need clarification on whether or not something is correct, you can always ask in the SailPoint Certified Professionals User Group.
