To obtain an IP address from a MAC address, what mechanism is used?

A.
Reverse Address Resolution Protocol (RARP)

B.
Address Resolution Protocol (ARP)

C.
Data Link layer

D.
Network Address Translation (NAT)

Explanation:

includes a MAC address and a request to be informed of the IP address that should be
assigned to that MAC. Diskless workstations that need to obtain their IP address
from the network may use this process.
