In store and forward mode, the switch must receive the complete frame before forwarding takes place. The
destination and source addresses are read, the cyclic redundancy check (CRC) is performed, relevant filters are
applied, and the frame is forwarded. If the CRC is bad, the frame is discarded. The latency (or delay) through
the switch varies with frame length.
Incorrect Answers:
A: Is wrong because the latency changes with the frame size.
D: Is wrong because it waits for the complete name and not merely the destination address.
