Correct Answer - Option 1 : DHCP
Dynamic Host Configuration Protocol (DHCP):
- It serves as a bootstrap when a host is booted and supposed to be connected to the Internet, but the host does not know its IP address.
- It is used on UDP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks.
Reverse address resolution protocol (RARP):
It is used to an associate physical address with an IP address
The address resolution protocol (ARP)
- It is a protocol used by the Internet Protocol (IP) [RFC826], specifically IPv4, to map IP network addresses to the hardware addresses used by a data link protocol.
- The purpose of ARP is to resolve known IP addresses to unknown physical addresses.
- The protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer.
