Which of the port is not part of STP protocol?

The Spanning Tree Protocol (STP) is a protocol used to prevent loops in a network topology. It works by disabling certain links to prevent them from creating loops in the network. STP is implemented on a per-bridge basis and operates at the data link layer (Layer 2) of the OSI model.
There are four STP port states that a switch port can be in:
Blocking: The port is not forwarding any data but is still receiving BPDUs to determine the root bridge.
Listening: The port is still not forwarding data, but it has received information about the topology of the network from the root bridge.
Learning: The port is still not forwarding data, but it has learned the MAC addresses of the devices connected to it.
Forwarding: The port is forwarding data.
The port state that is not part of the STP protocol is "Discarding." This is because it is not a valid port state in STP. The correct term used in STP is "Blocking" (as mentioned above), which is when the port is not forwarding data but is still receiving information about the network topology.
Therefore, the answer is D. Discarding.
