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
It’s RARP:
A. ARP and RARP are different operations. ARP assumes that every
host knows the mapping between its own hardware address and protocol
address(es). Information gathered about other hosts is accumulated
in a small cache. All hosts are equal in status; there is no
distinction between clients and servers.
On the other hand, RARP requires one or more server hosts to maintain
a database of mappings from hardware address to protocol address and
respond to requests from client hosts.
