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
