A network administrator is troubleshooting intermittent connectivity issues in a LAN. The network uses a mix of hubs and switches. Users on the hub segment experience frequent collisions, while users on the switch segment do not. The administrator wants to reduce collisions on the hub segment without replacing the hub. Which action would be most effective?

Reduce the number of devices connected to the hub

Increase the hub's transmission power

Connect the hub to a switch port and enable port mirroring
