What action does the ARP process take when a host needs to build a frame, but the ARP cache does not contain an address mapping?

• The ARP process sends out an ARP request to the Ethernet broadcast address to discover the IPv4 address of the destination device.
• The ARP process sends out an ARP request to the IPv4 broadcast address to discover the MAC address of the destination device.
• The ARP process sends out an ARP request to the IPv4 broadcast address to discover the IPv4 address of the destination device.
• The ARP process sends out an ARP request to the Ethernet broadcast address to discover the MAC address of the destination device.

Explanation: The address resolution protocol (ARP) maintains a cache of MAC to IPv4 address mappings on the local computer. If there is no mapping in the cache for a specific IPv4 address, then the ARP process sends an Ethernet broadcast on the local link in an attempt to resolve the destination IPv4 address to a MAC address.
