How do switches and bridges learn where devices are located on a network?Bridges and switches learn addresses by copying the MAC address of the source device and placing it into the MAC address table. The port number that the frame entered is also recorded in the table and associated with the source MAC address.
What device filters and forwards traffic based of MAC address?Routers. Whereas switches and bridges make forwarding decisions base on Layer 2 MAC addresses, a router makes forwarding decisions based on Layer 3 addresses. Unlike a switch, a router is more concerned with routing network traffic along the most efficient path to the destination.
At which OSI layer does a router operate to forward network messages?Routers operate on the third layer of the OSI Model, the Network-Control Layer.
Which of the following performs filtering of multiple frames simultaneously based on MAC addresses?What is a switch? A multiport bridge that performs filtering based on MAC addresses, in addition to providing additional features not found in a bridge. What layer of the OSI model does a switch operate?
