      Question

      What is the function of DNS (Domain Name

      System)?
      A To assign dynamic IP addresses to devices Correct Answer Incorrect Answer
      B To translate human-readable domain names into IP addresses Correct Answer Incorrect Answer
      C To encrypt web traffic between browser and server Correct Answer Incorrect Answer
      D To route packets between different networks Correct Answer Incorrect Answer
      E To manage email delivery across the internet Correct Answer Incorrect Answer

      Solution

      DNS acts as the internet's phonebook — converting domain names to IP addresses (e.g., 203.x.x.x) that computers use. DNS operates on port 53. DNS poisoning/spoofing is a security attack where forged DNS responses redirect users to malicious sites (phishing banks).
