Correct answer: Stores and forwards frames in a buffer and performs error checking..
Why this is the answer
Frame switching, specifically store-and-forward switching, involves a switch receiving an entire Ethernet frame into its buffer before making any forwarding decisions. During this buffering, the switch calculates the Cyclic Redundancy Check (CRC) to detect any errors in the frame. If the CRC check passes, the switch then looks up the destination MAC address in its MAC address table to determine the correct egress port and forwards the frame. If errors are detected, the frame is dropped. This method ensures data integrity. Populating the ARP table is a function of ARP, not frame switching. Dropping MAC addresses not in the address table is incorrect; unknown unicast frames are flooded. Rewriting MAC addresses is typically associated with Network Address Translation (NAT) or specific security features, not standard frame switching.
