Question 29

Which two statements are correct about MAC addresses? (Choose two.)

Switches use the Address Resolution Protocol table to assign MAC addresses to network interface cards in the forwarding frame.

Switches use the destination MAC address to identify the next-hop destination and to change the destination MAC address in the frame.

The source and destination MAC addresses always remains static to the final destination.

The MAC address identifies the physical hardware.

Correct Answer: C, D

Switches do not change the destination MAC address when forwarding a frame; they simply forward the frame based on the MAC address table. The source and destination MAC addresses stay the same throughout the Layer 2 broadcast domain. Additionally, the MAC address is a unique identifier assigned to the network interface card, identifying the physical hardware.
