When a MAC address changes ports on a switch, the process involves both the removal of the old MAC address entry and the addition of a new entry for the new port. This occurs because a switch maintains a MAC address table, which maps MAC addresses to specific ports.

When a device with a particular MAC address moves to a different port, the switch detects this change through the frames that the device sends. It will then first remove the association of that MAC address from the old port, ensuring that the MAC address table is updated to avoid potential traffic misdirection. Subsequently, the switch will add a new entry for the MAC address linked to the new port, effectively updating its knowledge of where to forward packets destined for that MAC address.

This process is crucial for maintaining accurate and efficient network communication, as it allows the switch to route data to the correct port in scenarios where devices are relocated within the network. The incorrect options reflect different concepts or misunderstandings of MAC address management in switching. Static entries, for instance, would not be removed under normal circumstances, as they are fixed and do not adapt to changes in device location.
