Which switching method has the lowest level of latency?
- cut-through
- store-and-forward
- fragment-free
- fast-forward
Explanation:Fast-forward switching begins to forward a frame after reading the destination MAC address, resulting in the lowest latency. Fragment-free reads the first 64 bytes before forwarding. Store-and-forward has the highest latency because it reads the entire frame before beginning to forward it. Both fragment-free and fast-forward are types of cut-through switching.
