Question No : 5
A workstation has just resolved a browser URL to the IP address of a server. What protocol will
the workstation now use to determine the destination MAC address to be placed into frames
directed toward the server?
A. HTTP
B. DNS
C. DHCP
D. RARP
E. ARP
Answer: E
Explanation:
The RARP protocol is used to translate hardware interface addresses to protocol addresses. The
RARP message format is very similar to the ARP format. When the booting computer sends the
broadcast ARP request, it places its own hardware address in both the sending and receiving
fields in the encapsulated ARP data packet. The RARP server will fill in the correct sending and
receiving IP addresses in its response to the message. This way the booting computer will know
its IP address when it gets the message from the RARP server.
