  • Question
  • Which statement describes a spanning-tree network that has converged?

  • C. All switch and bridge ports are in either the forwarding or blocking state.
  • D. All switch and bridge ports are either blocking or looping.

  • Correct Answer
  • All switch and bridge ports are in either the forwarding or blocking state.
