The correct answer is NONE OF THE ABOVE

There is no DBCC SQLPREF command.

I presume you meant DBCC SQLPERF and not SQLPREF (which is not a DBCC option)
Other than the obvious typo, nice question.

And, assuming that the typo is corrected, the answer is still NONE OF THE ABOVE, because DBCC SQLPERF, as written in the question, gives an error message

What checks space in the log is DBCC SQLPERF(LogSpace), and the DBCC statement can do several other things, depending on parameters passed to it, some documented, some not.
The question is like asking "What session does KILL terminate?" with answers of 1, 0, 75 and 56452322

Great trolling question there!

My train of thought on seeing this went domething like this... SQLPREF? Something odd there. Isn't it meant to be SQLPERF? Never actually used it, being more a developer than a DBA, so let's look at BOL... Hah! Trick question! Hmm - the only safe course of action is to think like a computer, (if it can be called thinking). The answer is obviously "syntax error" or similar... Let's see what the multi-choice answers are.. oh! Syntax errors not on the list! Must be a typo, albeit a repeated one. Let's try DBCC SQLPERF then... Hmm - parameter missing! I really want to post a comment, but I can't unless I answer the question. Temporarily suspending my computer-like thinking, I deduce that the closest answer is the last one, and lo and behold, it awards me a point!

To be honest, I really feel as if I cheated. Steve, feel free to deduct that point.

Top marks for entertainment value though, even if that was accidental! It all goes to show how hard it can be to think like a computer!

What's amazing to me is the typo is in the subject of the question as well as the question itself.

And of course the "correct" answer is only half correct anyway as SQLPERF can also reset wait and latch statistics.

Is it required to be accurate in typing to be DBA? That's the question.

Carlo Romagnano SSC-Insane Points: 22601 More actions · Answer 9

Assuming we use DBCC SQLPERF with the parameter LOGSPACE the explanation is wrong.
"Check the amount of space available in a transaction log file."

BOL says the opposite "amount of space used" and not "the amount of space available".

From BOL:
LOGSPACE
Returns the current size of the transaction log and the percentage of log space used for each database. You can use this information to monitor the amount of space used in a transaction log.

Again 'typos' in the question (and the answer). Sometimes the 'typo' is there deliberately. So when do we know when this is the case and when not?

Just getting around to this question and I could not decipher a correct answer from the list of answers. I really do not like this question as currently constructed.

I am glad Gail brought up the issues with this question because I would do the same in this case.
