What are two features of ARP? (Choose two.)

Selecciona una o más de las siguientes respuestas posibles:

If a host is ready to send a packet to a local destination device and it has the IP address but not the MAC address of the destination, it generates an ARP broadcast.

When a host is encapsulating a packet into a frame, it refers to the MAC address table to determine the mapping of IP addresses to MAC addresses.
If no device responds to the ARP request, then the originating node will broadcast the data packet to all devices on the network segment.
If a device receiving an ARP request has the destination IPv4 address, it responds with an ARP reply.
