Answer

Fast-forward Explanation 1. Identify Switching Methods Store-and-forward checks the entire packet for errors, causing higher latency. Fragment-free checks the first 64 bytes, reducing latency compared to store-and-forward. Cut-through and fast-forward forward packets immediately after reading the destination address, minimizing latency. 2. Determine Lowest Latency Fast-forward is a type of cut-through switching that forwards packets without error checking, resulting in the lowest latency.
