Which of the following tools might be useful in data discovery efforts that are based on content analysis?

Data Loss Prevention (DLP) solutions are specifically designed to discover, monitor, and protect sensitive data by performing deep content inspection and contextual analysis across various data states (in use, in motion, at rest). They can identify specific patterns, keywords, or classifications of sensitive information, which is central to content-based data discovery.

Digital Rights Management (DRM) is used to control access to and usage of copyrighted material, not primarily for discovering sensitive content within data stores.

iSCSI (Internet Small Computer System Interface) is a protocol used for linking data storage facilities over IP networks, not for content analysis or data discovery.

Fibre Channel over Ethernet (FCoE) is a networking technology that encapsulates Fibre Channel frames over Ethernet networks, primarily for storage area networks, and does not perform content analysis.
