An organization recently acquired a Data Loss Prevention (DLP) solution, and two months after the...

The most likely reason sensitive data was leaked despite the implementation of a DLP solution is inadequate data classification. Without proper classification, the DLP system cannot identify or apply appropriate controls to sensitive data. DLP solutions rely on predefined rules and policies tied to data labels; if sensitive data isn't accurately classified, it may not trigger protections. Options A, C, and D address peripheral issues but do not explain the failure of the DLP system to detect and prevent the leak.
