Which Spanning Tree Protocol feature disables a port when it receives unexpected spanning tree messages on an access port?
BPDU Filter
Loop Guard
Root Guard
BPDU Guard
BPDU Guard is designed to protect the network by disabling a port that receives Bridge Protocol Data Units (BPDUs) unexpectedly, such as on access ports connected to end devices. If a BPDU is received on such a port, BPDU Guard places the port into an error-disabled state to prevent potential loops caused by unauthorized devices or misconfigurations. Root Guard prevents connected switches from becoming the root bridge but does not disable the port upon receiving BPDUs. Loop Guard prevents ports from transitioning to the forwarding state when BPDUs are no longer received but doesn't disable the port upon receiving them. BPDU Filter suppresses the sending and receiving of BPDUs but does not disable the port when BPDUs are detected.
