Which of the following roles allows for device detection configuration on a FortiGate?

The role that allows for device detection configuration on a FortiGate is the LAN role. In a typical FortiGate configuration, the LAN interface is designed for internal network connectivity, and device detection is a feature meant to identify and manage devices on the local area network. The purpose of device detection is to enable network visibility and control, allowing administrators to apply policies based on the types of devices connected to the network.

Device detection typically involves monitoring traffic patterns and recognizing the operating systems and types of devices being used, which is essential for managing security policies effectively. Since the LAN environment is where users and devices primarily connect, it’s the most suitable role for implementing device detection features.

On the other hand, the DMZ typically serves as a buffer zone between the internal network and an external network, often hosting publicly accessible services, which makes it less relevant for internal device detection. The WAN role represents the external network connection, primarily focused on outbound access and may involve different security measures; therefore, it does not serve the purpose of device detection in the local network context. The Undefined option is not a recognized designation for interface roles on a FortiGate device, making it irrelevant for this functionality.
