A. B. C. D.


Spanning Tree Protocol convergence (Layer 2 convergence) happens when bridges and switches have transitioned to either the forwarding or blocking state.

When layer 2 is converged, root bridge is elected and all port roles (Root, Designated and Non-Designated) in all switches are selected.

The correct answer to this question is A. converged.

Explanation: In a Spanning Tree Protocol (STP) network, the STP algorithm blocks some ports to prevent loops from forming. As a result, there is a period of time called the "convergence time" during which the STP algorithm determines which ports should be blocked or unblocked.

When all switch ports in a STP network are either in the blocking or forwarding state, the network is said to be "converged." This means that the STP algorithm has determined the optimal path for traffic and has blocked all other paths to prevent loops.

Option B, redundant, refers to the use of backup links or devices in a network to provide fault tolerance and prevent downtime in case of a failure. Option C, provisioned, refers to the process of setting up and configuring network devices. Option D, spanned, is not a term used in the context of STP networks.

Therefore, the correct answer is A. converged.
