Answer / guest

Answer: D

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.
