For 3CX server setup, what is recommended in terms of network adapter settings?

Disabling unused adapters is recommended for 3CX server setup because it helps streamline network traffic and reduces potential points of conflict. In a typical installation, having multiple network adapters can lead to complications in routing and connectivity, especially if some are not in use. By ensuring that only necessary adapters are enabled, the server's resources can be utilized more effectively, enhancing performance and security.

Keeping unused interfaces active could lead to confusion in network path selection and potential miscommunication within the system. Moreover, it can create unintended vulnerabilities, as each active adapter might expose the server to different network segments. Disabling those that are not utilized contributes to a cleaner, more efficient setup that is easier to manage and monitor.

In contrast, utilizing only virtual interfaces, keeping all adapters active, or limiting to one active interface do not support the best practices for optimizing the 3CX server's network configuration and management. Each of these options could introduce their own complications and does not maximize the server's operational efficiency.
