LIST-I LIST-II A. Address resolution protocol I. Map physical address to IP address B. Reverse address resolution protocol II. Used by host and router to seed notification of datagram problem back to the sender. C. Internet control message protocol III. Help a multi-cast router identify host in a LAN D. Internet Group message protocol IV. Map IP address to physical address.
Matching Network Protocols: ARP, RARP, ICMP, and IGMP
This question requires matching four network protocols (LIST-I) with their specific functions (LIST-II).
Protocol Function Analysis
- A. Address Resolution Protocol (ARP): The primary role of ARP is to resolve an IP address (Layer 3) into its corresponding physical MAC address (Layer 2) on a local network. This matches with: IV. Map IP address to physical address.
- B. Reverse Address Resolution Protocol (RARP): RARP performs the inverse function of ARP. It allows a host to discover its IP address when it only knows its physical MAC address. This matches with: I. Map physical address to IP address.
- C. Internet Control Message Protocol (ICMP): ICMP is used by network devices, like routers and hosts, to send error messages and operational information indicating, for example, that a requested service is not available or that a host or router could not be reached. This matches with: II. Used by host and router to seed notification of datagram problem back to the sender.
- D. Internet Group Management Protocol (IGMP): IGMP is a communication protocol used by IPv4 network devices for establishing multicast group memberships. It enables multicast routers to determine which hosts on the network have active group subscriptions. This matches with: III. Help a multi-cast router identify host in a LAN.
Final Matching
Based on the analysis, the correct matching is:
- A - IV
- B - I
- C - II
- D - III
This corresponds to Option 4 in the question.
