What mode in ESS prompts the user with a pop-up message asking whether to allow or deny traffic?

The correct answer is the Learn Mode. In this mode, the system actively monitors network traffic to establish a baseline of legitimate activity. When unrecognized or unusual traffic attempts to pass through the network, Learn Mode prompts the user with a pop-up message that asks whether to allow or deny the traffic. This interactive nature allows for manual assessment of potential threats or anomalies, ensuring that legitimate traffic is not erroneously blocked while enhancing the overall security posture.

This method contrasts with other tuning options, which either rely on predefined rules without user input or adjust settings automatically based on historical traffic patterns. Through Learn Mode, organizations benefit from an additional layer of scrutiny, allowing them to adapt their security measures according to real-time conditions rather than solely relying on automated responses.
