All users on a specific network segment report losing access to the wired network. During troubleshooting, the network administrator observes link lights on the workstations. When physically…

STP convergence causes a temporary loss of connectivity while the spanning tree algorithm recalculates, but port lights would not remain solid green continuously - some ports would be in a blocking state.

A power failure would cause link lights to go dark entirely, not remain solid green, as the switches or workstations would lose power.

Excessive bandwidth usage from normal traffic would show high activity on some ports but would not cause all ports across the switch to display solid, constant green activity simultaneously.

A broadcast storm occurs when broadcast or multicast frames loop continuously through the network due to a switching loop, causing exponential traffic multiplication. All switch port activity lights appear solid green because the ports are overwhelmed with constant traffic, which explains both the solid activity lights and the complete loss of connectivity for users on that segment.
