    The lesson is saying that a switch is a layer 2 device and that it is capable of sending packets to a specific MAC address because it builds a routing table. Since it is a layer 2 device and layer 2 does not deal with IP addressing, does this mean that every port in a switch has its own MAC address

    The quiz says managed and layered switches are layer 3 devices. So a "regular switch" is a layer 2 device and a "managed switch" like a router is a layer 3 device?
