[All Systems Security Certified Practitioner Questions]

When a station communicates on the network for the first time, which of the following protocol would search for and find the Internet Protocol (IP) address that matches with a known Ethernet address?

AAddress Resolution Protocol (ARP).

BReverse Address Resolution Protocol (RARP).

CInternet Control Message protocol (ICMP).

DUser Datagram Protocol (UDP).

Show Suggested Answer

Suggested Answer: B

The RARP protocol sends out a packet, which includes its MAC address and a request to be informed of the IP address that should be assigned to that MAC address.

ARP does the opposite by broadcasting a request to find the Ethernet address that matches a known IP address.

ICMP supports packets containing error, control, and informational messages (e.g. PING).

UDP runs over IP and is used primarily for broadcasting messages over a network.
