not of
a repeater?
A.) Switches forward packets based on the IPX or IP address
in the frame
B.) Switches forward packets based on the IP address in the
frame
C.) Switches forward packets based on the MAC address in the
frame

| How does a switch use store and forward?

buffers and
then looks up the destination address in its forwarding, or
switching,
table and determines the outgoing interface
C.) By using broadcast addresses as source addresses
