Answer
# 1
Answer: A C

The larger the packet, the greater the latency when using a
switch with

Store and Forward methods. This is due to the fact that
Store and

Forward switching copies the entire Frame into its buffer before

forwarding the frame. Cut Through switching only examines the

destination address before forwarding the packet and does
not copy the

frame into its buffer.
