This question is somewhat badly worded.
Not only was it confusing as to how the job steps are defined, but there appear to be two questions:
Now if you run the job and if it fails, will it create the output file?
If the file is already available in the location, will it write anything to the file?
This follow up question makes it seem like the answer to the first question has to be yes.
But if I understood the way the question is worded, the answer should be no.
However if I misunderstood the first question, and the answer is yes, then it stands to reason that the answer to the second question is also yes.
At which point I get confused, and end up answering yes.
