Yes, a poor question. However, it is part of the ISC2 game. I had many  
questions that could have gone either way. It wouldn't surprise me if  
some questions are like this one on the exam to mess with you.  
Purposely adding to the stress of the exam.  Also, a percetage of the  
questions are for "research purposes".
