I don't mind so much getting this one wrong, as I have learnt a lot along the way, and had a very interesting time trying to find the answer.
However, I do 100% fully consider this a trick question. Why? Because the author specifies the Service Pack when it comes to Windows Server, but omits it for SQL Server, which leaves you wondering therefore what is the correct answer, as it is very much SP specific. The default scenario would be to always maintain your servers with the latest SP, and therefore you would have at least SP2 (most likely SP3, maybe even SP4) on this SQL Server 2005 installation.
However, this question was about a previous (to current) version of SQL Server on a specific version of the SP, and the author deliberately omitted to specify that in the question.
That aside, a great question which, as I say, I had a great time researching. Thanks 😀
