What do you call a question that has correct or incorrect answer?
I call it a factual question.
Factual questions require fact-based answers. There is only one correct answer, which can be verified by referring to the text or other learning materials.
As evident from the word ‘factual’, this type of questions requires you to retrieve facts given in the passage. Examples are who, what, where, when, how and why questions.

In the study of logic, the term for something like that would be predicate. From Wikipedia

Either the answer given is true, or false, so the question with answer is a predicate.
