B. Only nonedge ports moving to the forwarding state generate a TC BPDU.
C. If either an edge port or a nonedge port moves to a block state, then a TC BPDU is generated.

Correct Answer: B Section: (none) Explanation
Explanation/Reference:
Explanation:
The IEEE 802.1D Spanning Tree Protocol was designed to keep a switched or bridged network loop free,
with adjustments made to the network topology dynamically. A topology change typically takes 30
seconds, where a port moves from the Blocking state to the Forwarding state after two intervals of the
Forward Delay timer. As technology has improved, 30 seconds has become an unbearable length of time
to wait for a production network to failover or “heal” itself during a problem.
