Which statement is true about ARP when inter-VLAN routing is being used on the network?
- When router-on-a-stick inter-VLAN routing is in use, each subinterface has a separate MAC address to send in response to ARP requests.
- When VLANs are in use, the switch responds to ARP requests with the MACaddress of the port to which the PC is connected.
- When router-on-a-stick inter-VLAN routing is in use, the router returns the MACaddress of the physical interface in response to ARP requests.
- When traditional inter-VLAN routing is in use, devices on all VLANs use the same physical router interface as their source of proxy ARP responses.
