141. Which statement about Ethernet switches is true?
A Symmetric switching allows connection between port of unlike bandwidth
and does not require memory buffering
B Memory buffering is used to prevent a bottleneck when port of different
bandwidth are connected on a symmetric switch
C The latency can be reduced if the switch utilizes the store and forward
method of switching Store and forward is better for error detection
D The cut through method of switching is faster because the switch forwards
the packet to the destination as soon as it reads the destination address
Answer: B
