Which advantage does the store-and-forward switching method have compared with the cut-through switching method?

  • collision detecting
  • frame error checking
  • faster frame forwarding
  • frame forwarding using IPv4 Layer 3 and 4 information
    Answers Explanation & Hints:

    A switch using the store-and-forward switching method performs an error check on an incoming frame by comparing the FCS value against its own FCS calculations after the entire frame is received. In comparison, a switch using the cut-through switching method makes quick forwarding decisions and starts the forwarding process without waiting for the entire frame to be received. Thus a switch using cut-through switching may send invalid frames to the network. The performance of store-and-forward switching is slower compared to cut-through switching performance. Collision detection is monitored by the sending device. Store-and-forward switching does not use IPv4 Layer 3 and 4 information for its forwarding decisions.
