Question

A financial services company must classify and protect a proprietary customer dataset stored in SharePoint and Exchange. The data consists of exact account numbers and customer names pulled from a structured database of 2 million records. The security architect finds that the built-in credit card and generic account-number sensitive information types (SITs) generate a high volume of false positives because many numbers match the pattern but do not belong to actual customers. The architect must design a classification solution that only matches values that exist in the company's real customer records. Which Microsoft Purview capability should be used?
