A written agreement or a document stipulating constraints and practices that a community computer network or an individual user must agree and adhere to is called an Acceptable Use Policy (AUP). Employees and students are required to sign an AUP when you sign up with an ISP. A good AUP will cover most provisions for network etiquette and indicate clearly the privacy levels of a member. The examples given in the multiple choices above are use cases for AUP apart from option D. If a user is not certain on the actions that should be taken in use cases like these, an AUP should be of great help.
