Single Answer
0What mode of switching is best suited to low-latency, high-throughput data transfer?
Answer Options
A
Store-and-forward switching
B
Blind switching
C
Forward switching
D
Cut-through switching
Correct Answer: D
Explanation
Cut-through switching forwards packets as soon as the destination address is known without waiting for the rest of the frame to arrive. This means that packets are not checked for integrity before being forwarded, optimizing throughput and reducing latency at the expense of error checking. Store-and-forward waits for the entire frame to allow it to be checked using a cyclic redundancy check (CRC) before forwarding it. Blind and forward switching were made up for this question.
