Question:
Which switching method ensures that the incoming frame is error-free before forwarding?

• cut-through
• FCS
• fragment free
• store-and-forward

Explanation: 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.
