Answer: A
Store-and-Forward switching copies the entire frame into its
buffer and
computes the CRC. If a CRC error is detected, the frame is
discarded, or
if the frame is a runt (less than 64 bytes including the
CRC) or a giant
(more than 1518 bytes including the CRC). The LAN switch
then looks up
the destination address in its switching table and
determines the
outgoing interface. The frame is then forwarded to the outgoing
interface. Cisco Catalyst 5000 switches uses the
Store-and-Forward
method. The problem with Store-and-Forward switching is
latency is
increased. Latency also varies with the size of the frame.
The larger
the frame, the more latency associated. This of course is
due to the
fact that the entire frame is copied into its buffer before
being
forwarded.

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
