Answer / guest
Answer: D
Cut-Through switching copies only the destination address
which is the
first 6 bytes after the frame preamble into its buffer. The
LAN switch
then looks up the destination address in its switching table and
determines the outgoing interface. The frame is then sent to the
interface. A cut-through switch provides reduced latency
because it
begins to forward the frame as soon as it read the
destination address
and determines the outgoing interface.
