Detailed explanation-1: -Fast-forward switching begins to forward a frame after reading the destination MAC address, resulting in the lowest latency.
Detailed explanation-2: -35. Which switching method has the lowest level of latency? cut-throughstore-and-forwardfragment-freefast-forwardExplanation:Fast-forward switching begins to forward a frame after reading the destinationMAC address, resulting in the lowest latency. Fragment-free reads the first 64 bytes beforeforwarding.
Detailed explanation-3: -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.)
Detailed explanation-4: -The primary advantage of cut-through Ethernet switches, compared to store-and-forward Ethernet switches, is lower latency. Cut-through Ethernet switches can support an end-to-end network delay latency of about 10 microseconds.
