The correct answer is a retention policy set to retain for 5 years and then delete. This configuration works because Microsoft Purview retention policies are designed to be applied at the site or folder level, allowing you to enforce a consistent lifecycle rule—such as keeping all documents in a specific SharePoint site for exactly five years after creation, followed by permanent deletion. On the SC-900 exam, this question tests your understanding of the difference between retention policies, which manage automated lifecycle actions across a scope, and retention labels, which require manual or rule-based application to individual items. A common trap is confusing retention policies with sensitivity labels or DLP policies, but remember: sensitivity labels handle classification and protection, while DLP policies prevent data loss, not retention. For a quick memory tip, think “Policy for the place, Label for the face”—policies apply broadly to locations like SharePoint sites, while labels tag specific content.
