A county IT shared-services team needs retention and deletion lifecycle concepts applied to old permit archives in Microsoft 365. Which Purview capability fits?

Microsoft Purview Data Lifecycle Management provides retention and deletion lifecycle controls so content is kept and disposed of according to organizational policy. A county IT shared-services team applying retention and deletion lifecycle concepts to old permit archives in Microsoft 365 should identify Data Lifecycle Management as the fitting Purview capability. Microsoft Purview eDiscovery Premium supports identification, collection, and review for litigation and investigations with holds and search, but it does not apply scheduled retention and disposal lifecycle policy to old permit archives. Microsoft Purview Information Protection classifies and protects content with sensitivity labels, encryption, and policies, but it does not retain and dispose of content according to policy; retention and disposal timing is Data Lifecycle Management's job. Microsoft Purview Data Loss Prevention monitors and blocks risky sharing or exfiltration to prevent data loss, but it does not retain or dispose of content according to a records schedule. Exam caveat: AB-900 links retain-and-dispose lifecycle concepts to Data Lifecycle Management—not eDiscovery Premium for investigations, Information Protection for classification, or Data Loss Prevention for preventing oversharing. Operational check: map permit archive classes to retention policies or labels, verify disposal eligibility only after the required period, and document exceptions for holds or active investigations.
