  4. fast frag
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cut-through switching reads only the first 6 bytes of the frame (the destination MAC address) before making the forwarding decision. This allows faster switching but increases error propagation since the entire frame isn't checked. Store-and-forward switching receives the entire frame before forwarding, making it slower but more reliable. Options C and D are not standard switching methods.
