BPDU Guard performs the function of shutting down a port if a BPDU is seen on that port. Therefore, the correct answer from the provided options is:
**Shuts down a port if a BPDU is seen on that port.**
BPDU Guard is typically used on ports configured with PortFast to prevent loops by ensuring that only end devices (like PCs and printers) are connected to the port. If a BPDU is detected, it indicates that a switch has been connected to the port, which could potentially create a loop in the network, so the port is shut down to prevent that.
