27. Which STP state sends and receives all data frames on the bridged port?
A. Blocking
B. Listening
C. Learning D. Forwarding
Answer: D
The purpose of the blocking state is to prevent the use of looped paths. A port in listening state prepares to forward data frames without populating the MAC address table. A port in learning state populates the MAC
address table but doesn't forward data frames. The forwarding port sends and receives all data frames on
the bridged port. Lastly, A port in the disabled state is virtually nonoperational.
