A switch can have multiple MAC addresses mapped to which of the following?

A switch can have multiple MAC addresses mapped to interfaces because each port on a switch can connect to different devices, each having its own unique MAC address. When devices are plugged into various ports, the switch learns the MAC addresses from incoming frames. This learning process enables the switch to build a MAC address table, which helps it direct network traffic efficiently.

By maintaining a mapping of MAC addresses to specific interfaces (or ports), the switch ensures that data is sent to the correct destination device within the local area network. This capability is essential for the proper functioning of a switch in a network environment, allowing for effective communication between multiple devices. The idea that a switch can maintain this mapping is fundamental to its role in handling Ethernet frames and making forwarding decisions based on the source and destination MAC addresses.
