DD certainly knew what each had done to protect the Stone.

Dungrollin:

Hold up a minute... At the start of year feast DD says that the 
second floor corridor is out of bounds.  Quirrell let the troll into 
the dungeons on Halloween.  But Harry saw the Mirror of Erised in a 
disused classroom during the Christmas holidays.

So the plan to protect the stone in the second floor corridor - no, 
hang on, they fall down the trapdoor... the plan to have the 
*entrance* to the hiding place of the stone on the second floor 
corridor - was decided on before the beginning of term.  Likewise, 
the stone was removed from Gringotts during the summer holidays.  
But the Mirror, (presumably the last bit of protection to be added 
to the obstacle course) wasn't put in place until the Christmas 
holidays.

So when was the troll put in place?

I'd bet after Halloween.  I'd bet that it was the same troll, that 
Quirrell had procured it *for* the obstacle course with DD's full 
knowledge, though he probably didn't mention that he had a special 
knack with them - he was, after all, rather good at affecting 
incompetence.

Either that, or Quirrell let the troll in, and once Ron and Harry 
had subdued it, DD thought it would be useful so it was put to work 
as a guard.  

Plausible?
