Spanning Tree Protocol - Technical MCQs

Q1:

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

A All switch and bridge ports are in the forwarding state.

B All switch and bridge ports are assigned as either root or designated ports.

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.

ANS:C - All switch and bridge ports are in either the forwarding or blocking state.

Convergence occurs when all ports on bridges and switches have transitioned to either the forwarding or blocking states. No data is forwarded until convergence is complete. Before data can be forwarded again, all devices must be updated.
