He should obey the policy because if you are trying to hack someone's account you are having access to all there files without them knowing and when you are having access to someone's files you can delete all there work or you can mess about with it and you should not tamper with any other network area.

11. 1.7 Demonstrate how personal data is backed up to appropriate media Show Charlie how to “back up “work effectively from your college computer onto a USB/Memory stick a) Show a printscreen of files on your college computer, paste the printscreen below. b) Show a printscreen of the files saved on your USB/Memory Stick, paste the printscreen below. c) Charlie isn’t aware that the college backs up all school data (full back up) regularly. Find about what happens and write a short paragraph why it is done. They back it up everyday and take it home at the end of the week incase a virus appears or it deletes any of your files. So if any of your work gets deleted or messed about with it will always be backed up so you will have all your work back.
