Which characteristic describes cut-through switching?
- Error-free fragments are forwarded, so switching occurs with lower latency.
- Frames are forwarded without any error checking.
- Only outgoing frames are checked for errors.
- Buffering is used to support different Ethernet speeds.
Answers Explanation & Hints:
Cut-through switching reduces latency by forwarding frames as soon as the destination MAC address and the corresponding switch port are read from the MAC address table. This switching method does not perform any error checking and does not use buffers to support different Ethernet speeds. Error checking and buffers are characteristics of store-and-forward switching.
