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.

How does the cut-through switching technique work? A.) By using broadcast address as source addresses B.) The switch waits only for the header to be received before it checks the destination address and starts forwarding the packets C.) The LAN switch copies the entire frame into its onboard buffers and then looks up the destination address in its forwarding, or switching, table and determines the outgoing interface D.) By using a Class I repeater in a collision domain
