Which AZ-700 Exam Topics Have the Most Tricky Questions?

I am currently preparing for the AZ-700 exam and trying to spend more time on the areas that tend to be most challenging in the actual exam. For those who have already taken the AZ-700 exam, which topics contain the trickiest or most confusing questions?
I am asking because I want to focus my revision on the topics that commonly catch candidates off guard, rather than spending equal time on every objective.
