A. Enable monitoring-only mode to permit further tuning of the solution.

Proper configuration and rule definition are important for DLP tools to function accurately. We recommend using monitor-only mode to minimize false positives while evaluating your actual operational situation.

A. Enable monitoring-only mode to permit further tuning of the solution. Here’s a concise rationale for why this option is the most effective: Enabling monitoring-only mode allows the DLP tool to continue monitoring and generating alerts without taking any enforcement actions (such as blocking or quarantining files). This approach temporarily reduces the impact of false positives on administrators, enabling them to analyze and understand the alerts more comprehensively. Further tuning of the DLP solution based on the data gathered during the monitoring-only period helps in identifying patterns and refining policies to reduce false positives while maintaining effective detection of actual data breaches or policy violations.

Should be C. Enabling monitoring-only mode (option A) may provide insights for further tuning, but it does not directly address the issue itself. Educating staff about risks (option B) is important for overall security awareness, but it may not immediately reduce false positives. Ensuring the latest signature files and regular updates (option D) is essential for maintaining the effectiveness of the DLP tool, but it may not directly address the issue of false positives.

from the internet: To address this issue, administrators should enable monitoring-only mode in order to fine-tune the solution. This will allow them to monitor system activity without immediately taking action on any alerts that are triggered by suspicious activity.

Why not C ?

A is the answer

it shoud be C

Why signature files need for DLP solution? I think D isn't correct answer
