A corrupted file system is now repaired and back in use. Some， but not all of the files within the file  systems have been deleted. The only backup of this file system is a month-old tar archive. This archive will need to be restored as root.  Which two statements correctly describe the effects of the restore operation？（）

Files found in the file system that are also on tape will NOT be overwritten.

The missing files， present on the backup tape， are restored to the file system with the data as it was when the backup was taken.

The access times are preserved by tar and will reflect the time when a user last accessed the data.

The modification time on the files restored by tar will be preserved and will reflect the time the file was last modified before the backup， NOT the time of the restore operation.
