Correct answer C&D A. Switches use the Address Resolution Protocol table to assign MAC addresses to network interface cards in the forwarding frame: This is incorrect. The Address Resolution Protocol (ARP) is used by devices to map IP addresses to MAC addresses, but it does not assign MAC addresses to NICs. Switches use a MAC address table to map MAC addresses to specific switch ports. B. Switches use the destination MAC address to identify the next-hop destination and to change the destination MAC address in the frame: This is incorrect because switches do not alter the destination MAC address in the frame. They forward the frame based on the destination MAC address but do not modify it.

Switches don't change the destination mac address in a frame when forwarding it. The source and destination mac information is preserved from the source to destination inside a layer 2 broadcast domain. Answer should be CD
