When a switch configuration includes a user-defined error threshold on a per-port basis, to which switching method will the switch revert when the error threshold is reached?

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

Explanation: When a switch is configured for cut-through switching, it can be set to monitor error rates on a per-port basis; if a user-defined error threshold is reached, the port automatically reverts to store-and-forward switching to perform error checking on all frames before forwarding. Once the error rate drops below the threshold, it changes back to cut-through switching.
