Which switching method examines the destination MAC address as the frame is being received and then begins forwarding the frame prior to receiving the entire frame?

Cut-through switching reads the destination MAC address as soon as it arrives in the frame header and immediately begins forwarding the frame to the destination port without waiting for the entire frame to be received. This provides lower latency than store-and-forward switching but may forward corrupted frames since error checking happens after forwarding begins. Modified cut-through and fragment-free are variations that wait slightly longer to reduce errors, while store-and-forward receives the complete frame before forwarding.
