第3题：

What are two characteristics of "store and forward" switching? (Select two answer choices)

A．Latency fluctuates regardless of frame. size.

B．The switch receives the complete frame. before beginning to forward it.

C．Latency through the switch varies with frame. length.

D．The switch checks the destination address upon receipt of headers.

正确答案：BC
解析：Explanation:
With store-and-forward, the entire frame. is received by the switch before the first bit of the frame. is forwarded. As soon as the incoming switch port receives enough of the frame. to see the destination MAC address, the forwarding decision is made and the frame. is transmitted out the appropriate outgoing port to the destination device. So, each frame. might experience slightly less latency. Store and forward switching may add latency when compared to other switching methods such as cut through, but it can reduce the amount of errors that become forwarded through a network.

Incorrect Answers:
A. The amount of latency that is introduced with this method of switching is dependent on the size of the frame, as the switch must wait to receive the entire frame. before sending it.

D. The switch must wait for the entire frame. before forwarding it on, and not just the headers.
