| Question ID 14408 | 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?
|
| Option A | HTTP
|
| Option B | DNS
|
| Option C | DHCP
|
| Option D | RARP
|
| Option E | ARP
|
| Correct Answer | E |
Explanation 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
