A. B. C. D.B
The process associated with spanning-tree convergence is the election of the root bridge and the calculation of the best path from each switch to the root bridge.
In a network with multiple switches, Spanning Tree Protocol (STP) is used to prevent loops and ensure that there is only one active path between any two network devices. STP elects a root bridge, which serves as the central point for the topology.
Once the root bridge is elected, each switch in the network determines the best path to reach the root bridge by calculating the cost of each link. The cost of a link is determined by the speed of the link, so faster links have lower costs than slower links.
After the path costs are calculated, STP selects the best path from each switch to the root bridge. The path with the lowest total cost is selected, and all other paths are blocked. This process ensures that there is only one active path between any two devices, and that there are no loops in the network.
During this process, STP also elects designated and non-designated ports. A designated port is the port that is used to forward traffic towards the root bridge, while a non-designated port is a port that is blocked.
Therefore, the correct answer to the question is B. Electing designated ports. While the calculation of the path cost and the assignment of port IDs are important aspects of STP, they are not directly associated with spanning-tree convergence. The convergence process primarily involves the election of the root bridge and the selection of the best path from each switch to the root bridge.
