Suggested answer: B

Explanation:

Address Resolution Protocol (ARP) is a network maintenance protocol of the TCP/IP protocol suite. It is responsible for the resolution of IP addresses to media access control (MAC) addresses of a network interface card (NIC). The ARP cache is used to maintain a correlation between a MAC address and its corresponding IP address. ARP provides the protocol rules for making this correlation and providing address conversion in both directions. ARP is limited to physical network systems that support broadcast packets.

Answer option A is incorrect. The Dynamic Host Configuration Protocol (DHCP) is a computer networking protocol used by hosts (DHCP clients) to retrieve IP address assignments and other configuration information. DHCP uses a clientserver architecture. The client sends a broadcast request for configuration information. The DHCP server receives the request and responds with configuration information from its configuration database. In the absence of DHCP, all hosts on a network must be manually configured individually - a time-consuming and often error-prone undertaking. DHCP is popular with ISP's because it allows a host to obtain a temporary IP address.

Answer option D is incorrect. Reverse Address Resolution Protocol (RARP) is a Network layer protocol used to obtain an IP address for a given hardware (MAC) address. RARP is sort of the reverse of an ARP. Common protocols that use RARP are BOOTP and DHCP.

Answer option C is incorrect. Protocol-Independent Multicast (PIM) is a family of multicast routing protocols for Internet Protocol (IP) networks that provide oneto-many and many-to-many distribution of data over a LAN, WAN, or the Internet. It is termed protocol-independent because PIM does not include its own topology discovery mechanism, but instead uses routing information supplied by other traditional routing protocols, such as Border Gateway Protocol (BGP).
