Standard Exam Demonstration

This is a standard exam sample. It just demonstrates the question types which you can create using Visual CertExam Designer.

1. You are a software developer for a sporting goods company. You are creating an ASP.NET application for the marketing department. The application provides access to sales and marketing data. The data is stored in a Microsoft SQL Server2000 database named MarketingDB on a server named MrktSrv.

You want to add a page to your ASP.NET application in order to display sales data from MarketingDB. You use a SqlConnection object to connect to the database.

You need to create a connection string to MarketingDB. Which string should you use? (Select the best choice.)

A. "Data Source=MarketingDB;Initial Catalog=MrktSrv;IntegratedSecurity=SSP1"
B. "Data Source=MrktSrv;Initial Catalog=MarketingDB;Integrated Security=SSP1"
C. "Provider=SQLOLEDB.1;Data Source=MrktSrv;Initial Catalog=MarketingDB;Integrated Security=SSP1"
D. "Provider=MSDASQL;Data Source=MrktSrv;Initial Catalog=MarketingDB;Integrated Security=SSP1"

Answer: A

To connect to a Microsoft SQL Server 2000 database using the SqlConnection object, in theconnection string you must specify the server name using the DataSource parameter, the database name using the Initial Catalog parameter, and the authentication method using the Integrated Security parameter.

It is not necessary to specify the Provider parameter because the SqlConnection object can be used only to establish a connection to Microsoft SQL Server databases.

Reference:

Microsoft.NET Framework SDK Documentation, "Reference", "Class Library", "System.Data.SqlClient", "SqlConnection Class", "Properties", "ConnectionString Property [C#]".

2. You are the administrator of the corporate Web server connected to the network based on the Windows 2000 domain. Windows 2000 Server and Internet Information Server 5.0 are installed on the Web server. Another employee administrates thenetwork.

You need to permit the network administrator to run Windows Update on the Web server for system files updating. You want to give him as few privileges as possible.

To which local group you should add the network administrator? (Select the best choice.)

A. Administrators
B. Backup Operators
C. Power Users
D. Replicator

Answer: A

To update your system files using WindowsUpdate, you must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. Therefore, the user must be a member of the Administrators local group in order to update system files using Windows Update.

Reference:

Windows 2000 Advanced Server Help, Index, "Windows Update".

Windows 2000 Advanced Server Help, Search, "Windows Update".

3.You create a user control named MenuBar that is defined in a file named MenuBar.ascx. In order to test the user control you create an ASP.NET page and place it in the same folder as the MenuBar.ascx file. You use the following line of code to include the user control in the ASP.NET page.



To make the user control available on the page you need to declare it using the Register directive.Which declaration should you use? (Select the best choice.)

A.
B.
C.
D.

Answer: C

Including the @ Register directive in a page or user control allows you to lay out custom server controls or user controls using declarative custom server control syntax.

Use the @ Register directive in the following situations.
- To declaratively add a custom ASP.NET server control to a page or usercontrol.
- To add a declarative user control to a page or user control.

For declarative user controls, use the tagname, tagprefix, and src attributes. The first two are always used together as a colon-separated pair (tagprefix:tagname) when you declare the control in the page. The src attribute value can be either a relative or absolute path to the user control source file from your...
