Question 7
Log files are a static snapshot of the performance of a system.
True
False
TRUE
REASON: the log files are the static snapshot of the performance of the system. As you might know, the log files are updated consistently with time, telling the performance of the system at that point of time. But say, you want to see the performance of the system an hour before, then the log files will provide you the statistics at that time, which will be static since the system now cannot update anything to the log file at that point of time.
