What component is responsible for detecting incoming traffic that matches specific IP addresses or subnets?

The correct choice is focused on the role of listeners in network traffic management. Listeners are designed to monitor and detect incoming traffic based on predetermined criteria, such as specific IP addresses or subnets. Essentially, a listener acts as an attentive observer on the network, continuously scanning for traffic patterns or requests directed at defined addresses. When traffic matches the criteria set within the listening configuration, the listener can then trigger certain actions or policies, making it a crucial component in the context of proactive traffic monitoring and filtering.

This capability allows for efficient traffic handling and ensures that only the desired requests are processed, enhancing both security and performance. In this way, listeners play a pivotal role in managing incoming traffic effectively in a network environment.
