Unix systems maintain up to which of the following date-time stamps ?
Answer: A
Unix systems maintain up to four date-time stamps.
The inode of a file in Unix file systems such as ext2 and ext3 holds the last access time (atime), the last modification time (mtime), the last inode change time (ctime), and the deletion time (dtime), which is set when the file is deleted. Hence up to four time stamps, which forensic examiners use to build timelines.
Three is the familiar number of MAC times on a live file, which is why it is a tempting wrong answer, but the question asks for the maximum maintained. Two or one are too few for any Unix file system.
