Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Elect root bridge using lowest bridge ID
STP first elects a root bridge based on lowest bridge ID. Then each non-root bridge selects one root port (lowest path cost to root). Next, each segment elects a designated port (lowest root path cost, then lowest bridge ID). All other ports become alternate (blocking). Finally, ports transition through blocking, listening, learning, and forwarding states.
