Which of the following protocols resolves IP addresses to MAC addresses?
A. DNS
B. ARP
C. RARP
D. NTP
Correct Answer: B
Explanation/Reference:
Explanation: ARP is used to convert an IP address to a physical address such as an Ethernet address. ARP has been implemented with many combinations of network and data link layer technologies, such as IPv4, Chaosnet, DECnet and Xerox PARC Universal Packet (PUP) using IEEE 802 standards, FDDI, X.25, Frame Relay and Asynchronous Transfer Mode (ATM). IPv4 over IEEE 802.3 and IEEE 802.11 is the most common case.
