What does LLMNR stand for?

  1. Local Link Multicast Name Resolution

  2. Link Local Multicast Name Resolution

  3. Linked List Multicast Name Resolution

  4. Local Loop Multicast Name Resolution

The correct answer is: Link Local Multicast Name Resolution

LLMNR stands for Link Local Multicast Name Resolution. This protocol is used by Microsoft Windows operating systems to perform name resolution for hosts on the same local link. LLMNR is not used over routers, making option A and C incorrect. Option D is incorrect because it includes the term "loop" which is not part of the acronym. Therefore, the correct answer is B.
