Which statement is correct about ARP in relation to ROAS?

Answer Options

A

Each physical interface has a unique MAC address, which responds to ARP requests.

B

Each subinterface has a unique MAC address, which responds to ARP requests.

C

Each IP address has a unique MAC address, which responds to ARP requests.

D

All of the above.

Correct Answer: A

Explanation

When ROAS is implemented, only the physical interface has a unique MAC address. All ARP requests for the IP addresses configured on the subinterfaces respond with the same MAC address. They are not unique MAC addresses, but on each VLAN they are unique in the sense that no other machines on the VLAN share the same MAC address.
