Description

Are you ready for SC-401, or do you only recognise the terms? Reading about Microsoft Purview is one thing; choosing between exact data match and document fingerprinting, or between a retention label and a retention policy, under time pressure is another. These practice tests show you exactly where you stand.

The course contains 500 original questions in five full-length tests of 100 questions each. They are written against the skills measured as of October 28, 2026 for exam SC-401: Administering Information Security in Microsoft 365, and follow the official weighting of its three domains: information protection, data loss prevention and retention, and risks, alerts and activities, including the newer area of protecting data used by AI services.

SC-401 replaced SC-400 in 2025. The scope moved: DSPM for AI, DLP for Microsoft 365 Copilot, Adaptive Protection, just-in-time protection for Endpoint DLP, adaptive scopes and Purview alerts in Microsoft Defender XDR are in; communication compliance, information barriers and privacy management are out. Older SC-400 material spends time on topics you will not see and misses topics you will.

The five tests build up step by step:

  • Test 1, Groundwork: one concept per question, short stems.

  • Test 2, In Practice: short scenarios that separate features which are easily confused.

  • Test 3, Trade-offs: two answers look right and one constraint decides.

  • Test 4, Under the Hood: roles, settings, cmdlets, defaults and limits.

  • Test 5, Exam Day: long multi-constraint scenarios at the pace of the real exam.

Every answer option has its own explanation, so you learn why a wrong option is wrong and what it actually does. Each question also has an overall explanation that ends with a link to the Microsoft Learn page it is based on.

Udemy reports your score per SC-401 domain after every attempt, so you can target your weakest area. The passing score is 80% for tests 1 to 4 and 85% for test 5, deliberately above the real exam, so a pass here means a margin rather than luck.

What this course is not: it is not a video course, and it does not contain real exam questions. It is a practice and feedback tool to use alongside the free Microsoft Learn training for SC-401 and hands-on time in a Microsoft 365 tenant.

Who this course is for:

  • This course is for Microsoft 365 administrators, security and compliance engineers, and IT professionals who are moving into information protection and data security, and who plan to take exam SC-401: Administering Information Security in Microsoft 365. It also suits students and career switchers who have worked through the Microsoft Learn paths and want to know whether they are ready, and consultants or data governance specialists who need a solid grasp of Microsoft Purview. If you prepared for the retired SC-400 (Microsoft Information Protection Administrator), note that SC-401 replaced it in 2025: protecting data used by AI services, Adaptive Protection, just-in-time protection for Endpoint DLP, adaptive scopes and responding to Purview alerts in Microsoft Defender XDR are now in scope, while communication compliance, information barriers and privacy management are not. This is a set of practice exams with detailed explanations. It checks and deepens your knowledge; it does not replace hands-on training or the official learning paths.
