• Setting aside the trace flag issue (I don't blame the question writer for Microsoft's inability to write proper documentation) the only problem I have with this question is the use of the term "best".

    To paraphrase an old quote about lawyers, ask five SQL Server professionals the best way to write a simple SELECT statement, and they'll give you six(teen) different answers.

    You could have made this question bulletproof by using the term "recommended" instead of "best". Even the flipped trace flag would be technically correct, because Microsoft actually does recommend using the wrong one on that page.
