What protocol is used on the Local Area Network (LAN) to obtain an IP address from its known MAC address?

A.
Reverse address resolution protocol (RARP)

B.
Address resolution protocol (ARP)

C.
Data link layer

D.
Network address translation (NAT)

Explanation:
RARP translates a MAC address into an IP address.
Incorrect Answers:
B: ARP translates the IP address into a MAC address, not the other way around.
C: Network address translation (NAT) is a methodology of remapping one IP address space into another IP
address space. NAT does handle MAC addresses.
D: The data link layer does not use IP addresses. It transfers data between adjacent network nodes in a wide
area network (WAN) or between nodes on the same local area network (LAN) segment.
