Microsoft 365 Administrator MS-102 Exam Ref PDF Free Download

Prepare for Microsoft Exam MS-102 with the Exam Ref by Orin Thomas. Download a free sample chapter and study pack covering the four-domain MS-102 outline measured as of April 28, 2026—the skills version currently in force. 

What You'll Find Inside:

• Core Exam Topics – Coverage mapped to the four domains in force: Manage security and threats by using Microsoft Defender XDR (30–35%), Deploy and manage a Microsoft 365 tenant (25–30%), Implement and manage Microsoft Entra identity and access (25–30%), and Manage compliance by using Microsoft Purview (10–15%)

• Exam Objective Organisation – Chapters follow the exam objectives directly, with strategic “what-if” scenarios designed to test the decision-making an administrator performs at the tenant level—role assignment, identity governance, threat response, and compliance configuration—rather than passive recall

• Key Topic Highlights – Must-know administrator concepts flagged in the text, with the Exam Ref’s scenario-driven approach forcing you to apply them under realistic tenant-level constraints

• End-of-Chapter Review – Concept recaps and scenario exercises, reflecting the Exam Ref’s assumption that you already have experience deploying and managing Microsoft 365 in cloud and hybrid environments

• Final Review – Strategies for the proctored exam, including how to handle the 700/1000 passing score and the interactive components Microsoft uses in role-based exams

• Glossary and Tool Coverage – Quick reference spanning Microsoft 365 admin center, Entra ID, Defender XDR (including Defender for Office 365, Endpoint, and Cloud Apps), and Microsoft Purview

• Practice Questions – Chapter-ending review questions plus realistic practice scenarios; Microsoft also offers a free Practice Assessment on Microsoft Learn, accessible from the MS-102 study guide page, though the Exam Ref itself does not bundle a separate test bank
