    • Question

      In a network, which protocol is used to determine the

      MAC address corresponding to a given IP address?
      A ARP Correct Answer Incorrect Answer
      B DNS Correct Answer Incorrect Answer
      C DHCP Correct Answer Incorrect Answer
      D ICMP Correct Answer Incorrect Answer
      E FTP Correct Answer Incorrect Answer

      Solution

      The Address Resolution Protocol (ARP) is used to map a known IP address to its corresponding MAC (Media Access Control) address. It is essential for communication within a local network where devices need the MAC address for packet delivery. Why Other Options are Wrong: b) DNS (Domain Name System) resolves domain names to IP addresses. c) DHCP assigns dynamic IP addresses to devices on a network. d) ICMP is used for error reporting and diagnostic functions, such as ping. e) FTP is a protocol for file transfer, unrelated to address resolution.
