سوال ۲۳ کنکور ارشد مهندسی کامپیوتر ۱۴۰۱

PASSAGE 2 (excerpt): "... Tests in our lab have shown that this approach allows you to get much more random bytes than anything else. Yes, there are cases where this approach allows recovering original data from a sector. But these cases are extremely rare in real data recovery scenarios, and even then, only a part of the recovered sector will contain valid data. There are tools that claim better bad sector recovery. But they utilize a statistical approach, an algorithm where the tool reads the bad sector a number of times and then reconstructs the 'original' sector by locating the bits that occur most often. While these tools claim this approach could improve the outcome, there is no evidence to back up the validity of such claims."

According to the passage, recovering original data from a sector ----------.
