address. The MAC address is a Data Link layer address that is embedded in a ROM on
the network device and is hard-coded to each network interface. It does not automate IP
configurations. 642-521

addresses. It does not automate IP configurations.
D: WINS resolves NetBIOS names to IP addresses. It does not automate IP
configurations.
