ISC2 Exam SSCP Topic 4 Question 59 Discussion
Topic #: 4
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?
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.
