Final answer:
Switches make determinations to forward frames based on information in the MAC address table.
Step-by-step explanation:
Switches make determinations to forward frames based off the information contained inside of the MAC address table of a switch. This table contains the association between MAC addresses and specific switch ports. When a frame arrives at a switch, it examines the destination MAC address in the frame's header and checks its MAC address table to determine the appropriate port to forward the frame to.
