DRAG DROP
Place the Spanning-Tree Protocol port state on its function by dragging the state on the left to the
correct target on the right. (Not all options on the left are used.)
Answer: 
Explanation:
STP switch port states:
Blocking – A port that would cause a switching loop, no user data is sent or received but it may go
into forwarding mode if the other links in use were to fail and the spanning tree algorithm
determines the port may transition to the forwarding state. BPDU data is still received in blocking
state.
Listening – The switch processes BPDUs and awaits possible new information that would cause it
to return to the blocking state.
Learning – While the port does not yet forward frames (packets) it does learn source addresses
from frames received and adds them to the filtering database (switching database)
Forwarding – A port receiving and sending data, normal operation. STP still monitors incoming
BPDUs that would indicate it should return to the blocking state to prevent a loop.
