Which switching method ensures that the incoming frame is error-free before forwarding?
- cut-through
- FCS
- fragment free
- store-and-forward
Answers Explanation & Hints: Two methods used by switches to transmit frames are store-and-forward and cut-through switching. The store-and-forward method performs error checking on the frame using the frame check sequence (FCS) value before sending the frame. In contrast, cut-through switching sends the frame as soon as the destination MAC address part of the header has been read and processed.
