Microsoft Certified: Identity and Access Administrator Associate Study Guide

A contractor needs a SharePoint role for one project, a script needs to call Microsoft Graph without a stored password, and a sign-in from an unfamiliar location needs a second factor before it goes anywhere. SC-300, the Microsoft Certified: Identity and Access Administrator Associate exam, is built around decisions exactly like these. This guide is the written companion to the practice exams: a complete, plain-language walk through everything the test covers, in one place, so you can read for understanding and then drill with the questions.

SC-300 is for the person who runs identity in Microsoft Entra: provisioning users and guests, standing up authentication and Conditional Access, integrating applications, and governing who keeps access over time. The exam rewards judgment far more than recall. Almost every scenario hands you two answers that both technically work and asks for the one that fits Zero Trust: verify explicitly, and keep the least privilege standing. Concretely, that means preferring a phishing-resistant method like a passkey over basic MFA, choosing a managed identity over an app credential you have to store and rotate, and making a privileged role eligible just-in-time in PIM rather than assigned around the clock.

The guide follows the four official domains and weights them the way the real exam does. You will spend the most time in Authentication and Access (25 to 30 percent), then move through User and Hybrid Identities, Workload Identities and Apps, and Identity Governance (each 20 to 25 percent). Each chapter builds the mental model first in everyday language, then separates the look-alike options that trip people up, such as an app registration (the blueprint) versus an enterprise application (the tenant instance), with comparison tables and decision trees, and closes with a cheat sheet you can review the night before.

Start at the top for the full path, or pick a domain from the list beside this page if you already know where you are weakest.
