ITIL Foundation (Version 5) Study Guide

Preparing for the ITIL Foundation (Version 5) exam? You are in the right place. This is the written companion to the practice tests, a plain-language walk through everything the exam covers, gathered in one place.

Foundation is a recall-and-understanding exam: 40 multiple-choice questions in 60 minutes, closed book, and 26 correct to pass. It rewards precision more than application. Most questions hand you a definition and check that you can tell it from its near neighbour, so the skill is holding boundaries steady: output versus outcome, product versus service, and above all whether the value chain is the whole ITIL Value System or only one of its five components. It also slips in superseded ITIL 4 wording, so a recurring choice is the Version 5 answer, eight lifecycle activities and five value-system components, over the older one.

The guide follows the official domains and weights them the way the exam does, so your reading lands where the marks are: the ITIL Value System (40%) and Key ITIL terms (30%) together make up most of the paper, with the Four Dimensions, the Lifecycle, value streams, AI, and other frameworks filling the rest. Each chapter builds the mental model in plain words, separates the look-alike options with comparison tables and decision trees, and closes with a cheat sheet. Start at the top, or pick a domain from the list beside this page.
