Which statement below is NOT true about the difference between cutthrough
and store-and-forward switching?

A.
Both methods operate at layer two of the OSI reference model.

B.
A cut-through switch introduces more latency than a store-andforward
switch.

C.
A store-and-forward switch reads the whole packet and checks its
validity before sending it to the next destination.

D.
A cut-through switch reads only the header on the incoming data
packet.

Explanation:
A cut-through switch provides less latency than a store-andforward

switch, as it forwards the frame before it has received the
complete frame. However, cut-through switches may also forward
defective or empty packets. Source: Virtual LANs by Mariana Smith
