SC-401 study plan

SC-401 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Implement information protection

  • Diagram the full sensitivity label lifecycle from creation through publishing, policy evaluation, and client application for Word, Excel, PowerPoint, Outlook, Teams, SharePoint, and OneDrive.

  • Build a six-label taxonomy (one parent plus sublabels) with distinct priority ordering, colors, and tooltips in a Microsoft Purview trial tenant.

  • Publish a label policy scoped to a pilot security group, then record observed client behavior for each label in a comparison table.

  • Configure one label with encryption set to 'Assign permissions now' and one with 'Let users assign permissions', and document the resulting co-authoring and offline access differences.

Your checkpoint

A working six-label taxonomy in a trial tenant plus a one-page label design record listing priority order, encryption mode per label, and observed client behavior matrix.

Week 2

Implement information protection

  • Configure auto-labeling for SharePoint and OneDrive using a sensitive information type condition, run the simulation, and record the match rate before enabling the policy.

  • Build a custom sensitive information type using a regular expression plus supporting keywords and confidence level, then validate it against five test documents.

  • Create one trainable classifier seed set and explain, in writing, when a trainable classifier is preferable to EDM or document fingerprinting.

  • Apply a document fingerprint to a template set and confirm detection on a modified copy of the source file.

  • Map container labeling (Teams, Microsoft 365 Groups, SharePoint sites) to its downstream effects on site access and guest permissions.

Your checkpoint

An auto-labeling simulation report showing match counts for at least two rule types, plus a written decision matrix comparing sensitive information types, EDM, fingerprinting, and trainable classifiers.

Week 3

Implement information protection

  • Configure role groups in the Microsoft Purview portal so a test user can create labels but cannot publish policies, and verify the restriction.

  • Integrate a labeled file scenario with Defender for Cloud Apps to enforce label-based protection on a third-party cloud app session.

  • Troubleshoot three simulated label propagation failures (label not appearing in client, encryption not applied, sublabel missing) and write the resolution for each.

  • Complete a 40-question practice set covering only Domain 1 and log every missed item with the underlying concept and the corrected rationale.

Your checkpoint

A Domain 1 troubleshooting log with three documented failures, root causes, and fixes, plus a scored practice set of at least 40 questions with a remediation list for every miss.

Week 4

Implement data loss prevention and retention

  • Create DLP policies across Exchange, SharePoint, OneDrive, Teams chat, and endpoint locations, and describe how workload-specific conditions behave differently.

  • Tune a policy from a broad template into a narrow custom rule using conditions, exceptions, and instance counts, then verify with test content.

  • Configure user notifications and policy tips, including override with business justification, and confirm the override appears in the audit trail.

  • Explain the precedence and default behavior when a user attempts to override a blocking action, and configure an alert threshold for a high-severity rule.

  • Distinguish adaptive protection from static DLP by enabling an insider risk level condition and documenting what triggers each risk level.

Your checkpoint

A five-location DLP policy set with tuned rules, working policy tips, and an exported DLP alert report showing one triggered incident per configured condition.

Week 5

Implement data loss prevention and retention

  • Build retention labels with retention periods, start-of-retention triggers, and disposition review, then apply them to SharePoint and Exchange content.

  • Configure a file plan with at least four records with distinct retention and disposition settings, and label records versus regulatory records correctly.

  • Demonstrate retention precedence by placing overlapping retention policies and labels on one item and recording which outcome wins.

  • Set up event-based retention with a custom event type and confirm the retention clock starts only after the event is created.

  • Design an endpoint DLP rule set that blocks and audits a specific sensitive file transfer while allowing a justified override.

Your checkpoint

A file plan of four records with documented retention outcomes, plus a precedence test log proving the applied result for three overlapping label and policy combinations.

Week 6

Manage risks, alerts, and activities

  • Configure an insider risk management policy for data theft by departing users and identify which indicators require the most tuning to avoid false positives.

  • Build a communication compliance policy with a classifier-based condition and triage two sample flagged items through the review workflow.

  • Navigate Activity Explorer and Audit log search to trace a single labeled file from creation through sharing, and reconstruct the sequence in writing.

  • Configure alert policies and alert thresholds for DLP and retention events, then route alerts to a review queue and document the triage path.

  • Explain how audit log retention policies and the audit retention default differ for E5 versus lower licensing tiers.

Your checkpoint

An end-to-end investigation write-up of one simulated risky-sharing incident, including the triggering policy, the alert, the audit evidence trail, and the triage decision.

Week 7

Manage risks, alerts, and activities & Implement data loss prevention and retention

  • Resolve a cross-domain scenario where a retention label prevents deletion that a DLP rule expects, and document the resolution order.

  • Tune an insider risk policy to remove at least two noisy indicators while preserving detection of the primary risk scenario.

  • Configure communication compliance and insider risk to escalate into the same review workflow, and verify both appear correctly for a reviewer.

  • Draft a data lifecycle governance summary that maps each workload to its applicable protection, DLP, and retention controls.

Your checkpoint

A one-page cross-domain control map covering at least four workloads, each with its label policy, DLP policy, retention mechanism, and alerting owner.

Week 8

Implement information protection & Implement data loss prevention and retention & Manage risks, alerts, and activities

  • Complete two full-length timed practice exams under exam conditions and record per-domain scores.

  • Rebuild from memory the top ten weak concepts identified across both practice exams, without notes.

  • Re-run the three most-missed hands-on configurations in a trial tenant until successful without reference material.

  • Consolidate all deliverables into a single study portfolio indexed by domain for final review.

Your checkpoint

Two scored timed practice exams with per-domain breakdowns showing at least 80 percent in every domain, plus a rebuilt-from-memory sheet of the ten highest-risk concepts.

Milestones

Week 2: Sensitivity label taxonomy, auto-labeling simulation, and at least one encryption mode are functioning in a trial tenant; sensitive information type, EDM, fingerprinting, and trainable classifiers are distinguishable in a written decision matrix without notes.

Week 4: A 40-question Domain 1 practice set is scored at 80 percent or higher, and the Domain 1 troubleshooting log shows root causes rather than symptom descriptions.

Week 6: A five-location DLP policy set triggers the expected alerts, retention precedence has been proven with three overlap cases, and one insider risk incident has been investigated end to end through the audit trail.

Week 8: Both timed practice exams score 80 percent or higher in each of the three domains, and no domain falls more than 5 points below the others.
