Which of the following is the fastest method for transmitting data using a switch?
  1. Store and forward
  2. Fully buffered
  3. Cut through
  4. Loop back
Explanation
Answer: C - The fastest among the switching methods for transmitting data through a switch is the cut-through method.

Key Takeaway: Cut through reads the frame's hardware address before starting to forward it. Store and forward buffers and performs a checksum on each frame before forwarding it on. Since there is no error checking with the cut-through method, it is significantly faster though less reliable than the store-and-forward method.
