Correct answer: frame switching.
Why this is the answer
Frame switching is the process where a switch examines the destination MAC address of an incoming frame and forwards it only out of the port(s) associated with that specific MAC address, as learned and stored in its MAC address table. This intelligent forwarding prevents unnecessary traffic on other ports. Frame flooding occurs when a switch doesn't have a destination MAC address in its table and sends the frame out of all ports except the incoming one. Frame filtering is a broader concept related to blocking frames based on various criteria, not just forwarding to a specific MAC. Frame pushing is not a standard networking term for this function.
