Question 17 of 40 describes a service provider whose request workflows only half work and asks which guiding principle it should apply first. Two of the four options look right, and telling them apart is what the ITIL 4 Foundation exam really measures. The paper itself is simple: 40 one-mark multiple-choice questions in 60 minutes, closed book, with 26 correct answers (65%) needed to pass and no deduction for a wrong answer.

Here is that question in full, written in the style of the real paper:
Question 17. A service provider wants to improve the way it fulfils service requests. Some of its current request workflows are quick and well liked by users; others regularly miss their targets. Which guiding principle should it apply FIRST?
A. Optimize and automate
B. Start where you are
C. Progress iteratively with feedback
D. Keep it simple and practical
Most candidates narrow this to B and C within seconds, and then hesitate. Improvement in ITIL 4 is iterative, so C feels safe. But the stem hands you two clues. It says some workflows already work well, and it asks what to do FIRST. Assessing what exists, keeping what works and measuring it directly before designing anything new is the whole of start where you are, so B is the answer. C is a true statement about ITIL that answers a different question: how to run the improvement once it has started. A is a trap of its own, because ITIL 4 automates only after something has been simplified and optimised, and D is sound advice that the stem never asks for.
