      Question

      Which of the following operation is performed by Domain

      Name Server (DNS)?
      A Resolve a data link layer address to the corresponding network layer address. Correct Answer Incorrect Answer
      B Transferring of a data between a client and a server to send and receive requests and corresponding responses by the networking server. Correct Answer Incorrect Answer
      C Mapping a domain name to an IP Address Correct Answer Incorrect Answer
      D Connects changing IP address to a fixed media access (MAC) address Correct Answer Incorrect Answer

      Solution

      • Why Correct: DNS translates human-readable domain names (like openai.com) into IP addresses (like 104.18.xx.xx), allowing communication over the internet.
      • Why Others are Wrong:
        • Option 1: That’s ARP (Address Resolution Protocol).
        • Option 2: That describes HTTP.
        • Option 4: That’s DHCP (assigns IPs to MAC addresses).
