What mode causes the ENS Firewall to automatically create an allow rule for network traffic that doesn't match an existing block rule?

Adaptive Mode is the correct choice because it is designed to take a proactive approach in managing network traffic. In this mode, the ENS (Endpoint Security) Firewall analyzes the network traffic and automatically creates allow rules for any traffic that does not match an existing block rule. This helps ensure that legitimate traffic can flow without interruption, enhancing the usability of the network while still maintaining security controls.

Adaptive Mode allows for a greater level of automation, adjusting dynamically to changes in traffic patterns and behaviors, which is crucial in environments where network conditions can frequently change. This automating capability helps minimize the administrative overhead of manually updating firewall rules as new applications and services are introduced or modified within the network.

The other modes mentioned, while they have their specific functions and use cases, either do not support automatic rule generation based on traffic patterns (like Static Mode) or are not specifically aimed at managing rules in the manner Adaptive Mode does. Learn Mode could be seen as analyzing traffic for future adjustments but does not directly allow traffic automatically, while Firewall Mode generally applies existing rules without the flexibility afforded in Adaptive Mode.
