When you copy a compressed NTFS file, Windows XP Professional uncompresses the file, copies the file, and then compresses the file again as a new file. This might take considerable time.

To add the connection to your project, finish the wizard by completing the fol lowing steps. 10. Click Next. You are presented with the option of saving the Connection string in the application configuration file as well as providing a name for the connection. By default, the selection is set to save the connection; this is probably a good idea for most applications. Saving your connection in the application configuration file would be advantageous if, after deployment, you wanted to point at a differ ent data source. Then you (or a systems administrator) could easily modify the configuration setting rather than having to change the connection string in code and recompile and redeploy the application. Once a connection string is saved to the application configuration file it can be accessed and modified using the Project Designer. Open the Project Designer by double-clicking the My Project icon (VB) or the Properties icon (C#) in Solution Explorer. After the Project Designer opens, click the Settings tab to access the connection strings stored in your application. 11. The Choose Your Database Objects page of the wizard allows you to select the Tables, Views, Stored Procedures, and so on to be used in your application. For this lesson, expand the Tables node and select the Customers and Orders tables. 12. Click Finish. A typed dataset with the connection object defined in the wizard is added to your project. Now that you ve completed the wizard, let s take a look at where the connection is and what it contains. The connection created as a result of running the wizard is located within the designer-generated dataset code file. To view the actual connection object, open the dataset in the Dataset Designer by double-clicking the dataset object in Solution Explorer. (The Dataset object is the NorthwindDataSet.xsd node.) Select the title bar of a TableAdapter on the design surface (for example, select CustomersTableAdapter). The connection information is available in the Properties window, where you can expand the node and see the name, modifier, and connection string.

There are several additional settings, detailed in Table 4-1.

When designing your DNS name resolution strategy, you should plan to integrate other networking services to optimize performance. In this section, you look at how Active Directory integration can improve network performance and lessen administrative overhead. You also see how DHCP not only automatically configures your client workstations with IP configuration information, but also communicates with DNS Server service to perform dynamic updates. Last, you will examine WINS and how DNS can be optimized to forward queries to a WINS server to resolve Network Basic Input/Output system (NetBIOS) names and services. Let s begin with Active Directory integration.

Correct Answers: B A. Incorrect: Any volume type can be mounted only in an empty folder on an NTFS volume, but FAT does not support mounting a separate drive to an empty folder. Therefore, the external drive does not need to have the NTFS file system, but the C:\ drive does. B. Correct: The C:\ drive must be converted to NTFS before external drive can be mounted to a folder. This answer has the proper syntax for converting the drive. C. Incorrect: Fsutil.exe is useful for modifying aspects of the file system, but it cannot be used to create folder mount points. D. Incorrect: The Format.exe utility is used to add a file system to a disk that has already been configured. It cannot be used to create folder mount points.

Structure your application to simplify the maintenance of your database access code. Describe how to best use SQL permissions to limit damage done by successful SQL

a. The server has been started for the first time. b. The server cannot communicate on the network. c. The server has been unauthorized by a senior network manager. d. The server is not running Windows Server 2003.
