Detailed technical explanation
How to think about this question
Sensitivity labels use Azure Information Protection (AIP) to apply rights management (RMS) policies, which encrypt documents using AES-256 and enforce usage restrictions such as copy/paste blocking or expiration dates. These labels can be automatically applied based on data classification rules or manually assigned by users, and they persist with the document even when shared externally via email or cloud storage. A real-world scenario is a legal firm labeling a contract as 'Confidential' to prevent unauthorized forwarding or printing, ensuring compliance with regulatory requirements like GDPR.
