Interesting answer. I would have expected it to be able to use only one protocol, with shared memory being the most efficient method (but not a test answer). So I chose named pipes.
Does it really use both? When/how would it select one protocol over the other?

Looking at the default values from the table at the bottom of this artical, I would take the correct answer as #3 "TCP/IP, Local Named Pipes" and I see most people who answered this question agree's with me.
Unless I am Missing Something??

I think a more complete explanation would be nice. I quickly chose the popular TCP/IP, Named Pipes - thinking even if it's the other way around, I didn't care because it seemed a silly question.
However, maybe it's not so silly. I'm not too familiar with shared memory, except I thought it similar to named pipes. What is the difference?
I see Shared memory is not even an option in Server or Client network utility from SQL Server running on a 2000 sp4 OS. The choices are:
Named Pipes
TCP/IP
Multi
NWLink
AppleTalk
Banyan
VIA

In BOL, I found:
For computers running Windows NT 4.0 or Windows 2000, the default server Net-Libraries are:
- TCP/IP Sockets.
- Named Pipes.
For computers running Windows 98, the default server Net-Libraries are:
- TCP/IP Sockets.
- Shared Memory.
Does IIS do something unusual to force SharedMem and NamedPipes? Or is the correct answer ... wrong?

The key is that IIS is communicated locally, so it'll probably use Shared Memory. Lookup BOL "Client and Server Net-Libraries".
"The client calls to the IPC API are transmitted to a server Net-Library by the underlying IPC. If it is a local IPC, calls are transmitted using a Windows operating IPC shared memory or local named pipes. If it is a network IPC, the network protocol stack on the client uses the network to communicate with the network protocol stack on the server."

Well, I searched the web high and low and finally I guess the answer.
I might be blind but I didn't find anything.
Do you have some reference?

Seems Win 2000 uses named pipes, not shared memory, which must be just for win 9x.
Might the question or answer need some adjusting?
