In Ethernet networking, how does a switch decide to which port to forward an incoming frame?
By utilizing the TTL field in the frame header
By using the frame's VLAN tag
By examining the frame's source IP address
By examining the frame's destination MAC address
Switches forward Ethernet frames by examining the destination Media Access Control (MAC) address in the frame's header. They consult their MAC address table to determine which port is associated with the destination MAC address and forward the frame accordingly. Source IP addresses, Time To Live (TTL) fields, and VLAN tags are not used by switches for basic frame forwarding decisions.
