A user in a small office with three employees has just purchased a new computer run ning Windows XP and has configured a network by using a four-port hub. She con nected her three existing computers running Windows 98 and her new computer running Windows XP, and then she used the Network Setup Wizard on the computer running Windows XP to create the network. She reports that she made no other changes. After sharing a few folders, she reports that everyone on the network can view and make changes to her shared files. She wants the users on her network to be able to view the files only, not edit or change them. What should you tell the owner to do (Choose all that apply.) A. Disable Simple File Sharing.

Windows XP provides access to local, shared, and offline files. A file name extension is a set of characters at the end of a file name that describes the type of information that is stored in the file. A file name extension can also indicate which application is associated with the file. File compression reduces the amount of disk space required for the storage of files and increases the amount of information that you can place on a single volume. This is useful on a volume that is running low on available disk space. Windows XP Professional supports file compression on NTFS volumes only. (Windows XP Home Edition does not support file compression.) In Windows XP Professional, you can protect files and folders by using the Encrypting File System (EFS). (EFS is not available in Windows XP Home Edition.) EFS encodes your files so that even if a person can obtain the file, he cannot read it.

Supporting Windows XP File and Folder Access
Disk quotas allow you to track and control disk space usage. You can enable disk quotas strictly for the purpose of monitoring how much disk space each user is consuming, or you can take the additional step to configure and enforce quota limits. Every file and folder on an NTFS volume has a discretionary access control list (DACL) associated with it. The DACL contains the user accounts and groups that have been assigned permissions to a resource and the permissions that have been granted. Each entry in the DACL is called an access control entry (ACE). A user account or a group that the user account is a member of must be listed as an ACE in the DACL for the user account to gain access to a resource. Basic file and folder permissions include the following: List Folder Contents, Read, Write, Read & Execute, Modify, and Full Control. When assigning permissions, you should grant the user the lowest level of permis sion required to access the resources in the appropriate fashion. For each permission, you can choose one of two states: allow or deny. In most cases, you will allow specific permissions, which provide the user with the ability to perform the specified function. When you deny a permission, that denial overrides any allowances of the same permission that may come from other sources. When you calculate effective NTFS permissions, you should combine all allowed permissions. A denied permission always overrides an allowed permission. To create shared folders on a computer running Windows XP Professional, you must be a member of the Administrators or Power Users groups. Also, users granted the Create Permanent Shared Objects user right can share folders. Using a $ at the end of a share name creates a hidden share, which prevents users who are browsing the network from seeing the share. Users have to know the name and location of the share to connect to it. You can share the same folder multiple times with different share names and dif ferent permissions assignments. This sharing is useful if diverse groups of users would recognize the same data more intuitively under different share names or if different users require different levels of share permissions for the same folder. You can protect shared folders by using shared folder permissions or by using a combination of shared folder and NTFS permissions. When shared and NTFS permissions are applied, the cumulative permissions of both are determined, and the most restrictive of those permissions create the user s effective permission. Simple File Sharing is a simplified sharing model that allows users to easily share folders and files with other local users on the same computer or with users in a workgroup without having to worry about configuring NTFS permissions and standard shared folders.
