You are asked to configure 802.

This scenario describes a specific use case where a switch port is shared by multiple devices (e.g., via a downstream unmanaged switch), and you want to simplify the authentication process.

Single Supplicant Mode (Option A):In this mode, the switch requires only thefirst devicethat connects to the port to successfully authenticate via 802.1X. Once that first device is authorized, the switch "opens" the port for all traffic. This meansall subsequent devicesattached to that same downstream switch are permitted to access the network without undergoing their own authentication.

Other Modes:

Single-secure supplicant (C):Only allows the first authenticated device; all others are blocked.

Multiple supplicant (D):Requireseverydevice to authenticate individually.

MAC RADIUS (B):This is an authentication method, not a port-control mode.
