Which of the following is not a recognized security feature of the Einstein Trust Layer?

The correct choice is based on the understanding of the features associated with the Einstein Trust Layer. The Einstein Trust Layer is designed to enhance data security and privacy while leveraging AI capabilities in Salesforce. Among its recognized features are measures like Prompt Defense, which helps prevent unauthorized access by monitoring and responding to security threats in real time; Zero Data Retention, which ensures that sensitive data is not stored beyond its necessary usage period, thereby reducing privacy risks; and Data Masking, which alters data to protect sensitive information from being exposed.

Data Staging, on the other hand, is not recognized as a security feature of the Einstein Trust Layer. It typically refers to the process of preparing and organizing data before it is processed or analyzed, which does not inherently involve security mechanisms aimed at protecting user data. Thus, it does not align with the specific security focus of the features included in the Einstein Trust Layer.
