Which one of the following switching modes reads at least 64 bytes of the frame before forwarding it to the destination?
Cut-Through
Fragment-Free
Store-and-Forward
Fast-Forward
Fragment-Free switching works like Cut-Through switching except that it checks the first 64 bytes of the frame, which is where most of the collisions and network errors occur, before being forwarded to the destination. In Cut-Through switching mode, only the frame's first 6 bytes (destination MAC address) is checked before being forwarded to the destination. In Store-and-Forward switching mode, the whole frame is stored in the memory buffer for CRC calculation for errors before being forwarded to the destination.
