SC-401 Practice Test: Protect Data, Enforce Policy, Respond to Risk
Prepare around Microsoft Purview information protection, data loss prevention, retention, insider risk, alerts, and investigation workflows.
The three-pillar blueprint
1. Information protection
Discover sensitive data, configure sensitive information types and classifiers, publish sensitivity labels, apply encryption, and extend protection to endpoints and repositories.
2. DLP and retention
Design policy scope, rules, actions, exceptions, alerts, testing, records controls, event-based retention, and disposition processes.
3. Risks and activities
Work with insider risk, communication compliance, activity exploration, alerts, investigations, audit, and information-security incidents.
Microsoft currently weights each pillar at approximately 30–35%, so preparation should be balanced. Ignoring one pillar can create a large readiness gap.
Translate every question into a policy decision
When a scenario looks complicated, separate it into five parts: the data being protected, where it lives, who can access it, what action should occur, and how administrators will detect or investigate the event. That method helps distinguish similar controls.
- Classification: What identifies the content—built-in type, custom type, exact data match, fingerprint, or trainable classifier?
- Protection: Does the requirement need a label, encryption, content marking, container settings, or endpoint control?
- Lifecycle: Should content be retained, deleted, declared as a record, reviewed, or placed under event-based retention?
- Risk: Is the problem data leakage, insider activity, communication risk, policy tuning, or incident investigation?
Administrator lab checklist
- Explore Data Explorer and Content Explorer and understand the permissions they require.
- Create a test sensitivity label and a publishing policy; observe user-facing behavior.
- Build a DLP policy in test mode, review matches and alerts, then explain when simulation is safer than immediate enforcement.
- Compare retention policies, retention labels, records management, and disposition review.
- Review insider-risk prerequisites, indicators, privacy controls, cases, and alert triage.
- Practice locating evidence through the Microsoft Defender and Microsoft Purview portals.
