Answer-Which of the following protocols is used for resolving IP addresses to MAC addresses in a network?

Question

Accepted Answer

The Address Resolution Protocol ARP is used to map an IP address to a MAC address within a local area network LAN. It operates at the Network Layer Layer 3 and communicates with the Data Link Layer Layer 2 to retrieve the physical address of the destination device. When a device wants to send data to another device within the same network, it broadcasts an ARP request to resolve the MAC address corresponding to the known IP address.   Why Other Options Are Incorrect     DHCP Dynamic Host Configuration Protocol assigns IP addresses dynamically to devices but does not resolve IP to MAC addresses.    ICMP Internet Control Message Protocol is used for diagnostic purposes, such as ping tests, and does not handle address resolution.    DNS The Domain Name System resolves domain names e.g., www.example.com  to IP addresses, not MAC addresses.    FTP File Transfer Protocol is an application layer protocol for transferring files, unrelated to address resolution.
