I am studying from Configuring Windows Server 2008 Network Infrastructure (our environment still has significant Windows 2008 R2 servers), and one question asks

You are working on a Windows Server 2008 R2 computer named WS08A. You cannot connect to computers running Windows XP on the local network by specifying them by name in a UNC path such as \computer1.

What can you do to enable your computer to connect to these computers by specifying them in a UNC?

The choices are

Enable IPv6 on WS08A.

Enable NetBIOS on WS08A.

Enable Local Link Multicast Name Resolution (LLMNR) on WS08A.

Disable IPv6 on WS08A.

I believe the correct choice is Enable Local Link Multicast Name Resolution (LLMNR) on WS08A. because it replaces NetBIOS. However, the textbook says Enable NetBIOS on WS08A is the answer.

When I researched this, I read somewhere that using LLMRN to connect to a 32bit machine will take longer than if you use NetBIOS, but this connection is still possible.

If this is the case, why can't they re-write the question to ask,

"Which is the faster way to connect to Windows XP by specifying them in a UNC?"

Or is there something else I am missing?

You can't use LLMNR in that scenario because it was introduced with Windows Vista/Server 2008. Windows XP does not support it.

Since Windows XP is end of life, and nobody should be using it anymore, (though some are) you can use LLMNR once you have completely eliminated XP from your environment.
