Two network engineers are discussing the methods used to forward frames through a switch. What is an important concept related to the cut-through method of switching?

• The fragment-free switching offers the lowest level of latency.
• Fast-forward switching can be viewed as a compromise between store-and-forward switching and fragment-free switching.
• Fragment-free switching is the typical cut-through method of switching.
• Packets can be relayed with errors when fast-forward switching is used.

Explanation:  Fast-forward switching offers the lowest level of latency and it is the typical cut-through method of switching. Fragment-free switching can be viewed as a compromise between store-and-forward switching and fast-forward switching. Because fast-forward switching starts forwarding before the entire packet has been received, there may be times when packets are relayed with errors.
