In RSTP configuration, which port is disabled when receiving BPDUs?

In Rapid Spanning Tree Protocol (RSTP) configuration, when a port receives Bridge Protocol Data Units (BPDUs), it indicates the presence of a designated bridge, which leads to the port transitioning through various states to maintain a loop-free topology. If a port continues to receive BPDUs after being designated as a blocking port due to a network topology change or a failure condition, RSTP will disable that port to prevent any forwarding loops.

The correct answer signifies that the port ge-0/0/14.0 would enter a disabled state upon receiving BPDUs under specific conditions, reinforcing RSTP’s goal of maintaining a stable and efficient spanning tree. It is crucial to note that each port's designation depends on the network's topology changes and the configuration of the switches involved. Therefore, when troubleshooting or analyzing an RSTP implementation, recognizing which ports transition to a disabled state upon receiving BPDUs can be key to understanding the state of the network.
