What makes the SC-401 hard
SC-400 retired in May 2025, and SC-401 is what replaced it: the same Purview core, rebuilt around a data-security role, with AI security added. Study material written for SC-400 misses a chunk of the current blueprint.
The exam lives in Microsoft Purview’s decision points: sensitivity labels versus sensitive information types versus trainable classifiers, DLP policy scoping and priority when rules collide, retention labels versus retention policies, and insider risk management thresholds. The newer layer is securing data that AI touches: Copilot interactions, DSPM for AI, and oversharing surfaced by AI tools.
The three domains are weighted almost identically, at 30 to 35% each, so there is no section that can safely be skimmed. Information protection, DLP and retention, and risk and alert management each decide roughly a third of the score.
