An airport operations IT team needs executive closed-session minutes marked as highly confidential in Microsoft 365. Which Purview use case fits?

Sensitivity labels in Microsoft Purview classify and protect content, including applying protections appropriate to highly confidential material. An airport operations IT team that needs executive closed-session minutes marked as highly confidential in Microsoft 365 should apply a sensitivity label that classifies and protects those minutes according to confidentiality requirements. Applying a retention label that preserves the minutes for the records schedule retention period manages retention only; it does not classify or protect the content from unauthorized viewing the way a sensitivity label does. Applying a DLP policy that monitors and restricts sharing of the minutes for confidentiality can detect and block risky sharing, but it does not classify and protect the minutes themselves with a highly confidential label and persistent protections the way a sensitivity label does. Applying an eDiscovery hold that preserves the minutes for legal review of confidentiality matters keeps the content discoverable for legal review, but it does not classify the minutes as highly confidential or apply protective controls, so it does not prevent unauthorized viewing the way a sensitivity label does. Exam caveat: AB-900 sensitivity-label use cases emphasize classification plus protection—not retention scheduling, DLP monitoring, or eDiscovery preservation. Operational check: apply the highly confidential label with encryption and sharing restrictions as policy requires, limit owners and viewers to authorized executives and clerks, and verify external sharing is blocked for that content.
