You have a Microsoft ASP.NET application.
You use trace statements in the Web pages of the application.
You need to capture trace messages only for specific Web pages in the application.
What should you do?

• A. Enable tracing in the Machine.config file of the Web server.
• B. Enable tracing in the Web.config file in the root of the Web site.
• C. Enable tracing in the Web.config file in the folder of the application.
• D. Enable tracing in the individual Web pages.

You are developing a Web application. The application has a page named Report.aspx.
The code-behind file for Report.aspx changes frequently. The rest of the application remains the same.
You need to ensure that the code-behind file of Report.aspx can be precompiled and then deployed to the
Web server without redeploying the application.
What should you do?

• A. Use the Copy Web Site tool to copy the App_Code folder to the Web server.
• B. Use the Publish Web Site tool and select the Allow this precompiled site to be updatable option.
• C. Use the Publish Web Site tool and select the Use fixed naming and single page assemblies option.
• D. Use the Copy Web Site tool to copy Report.aspx.cs to the Web server.

You are creating a Web application.
The Web application manages an XML document that contains a catalog of books.
You need to ensure that nodes named Magazine are not added to the catalog.
What should you do?

• A. Attach the following handler to the XmlDocument.NodeInserting event. void xmlDocument_NodeInserting(object sender, XmlNodeChangedEventArgs e){ if (e.Node.Name == "Magazine"){ throw new ApplicationException("Magazines are not allowed."); } }
• B. Attach the following handler to the XmlDocument.NodeInserted event. void xmlDocument_NodeInserted(object sender, XmlNodeChangedEventArgs e){ if (e.Node.Name == "Magazine"){ throw new ApplicationException("Magazines are not allowed."); } }
• C. Attach the following handler to the XmlDocument.NodeChanging event. void xmlDocument_NodeChanging(object sender, XmlNodeChangedEventArgs e){ if (e.Node.Name == "Magazine"){ throw new ApplicationException("Magazines are not allowed."); } }
• D. Attach the following handler to the XmlDocument.NodeChanged event. void xmlDocument_NodeChanged(object sender, XmlNodeChangedEventArgs e){ if (e.Node.Name == "Magazine"){ throw new ApplicationException("Magazines are not allowed."); } }

You are developing a Microsoft ASP.NET Web site.
You add a user control named WebUserControl1 to a Web Form. The control is defined in the same Web
site project.
After adding the markup for the control to the Web Form, you receive the following error message:
"Unknown server tag: 'uc1:WebUserControl1'"
You need to resolve the error.
What should you do?

• A. Add a <%@ Register %> directive to the top of the Web Form along with the Src and TagPrefix attributes for the WebUserControl1.ascx file.
• B. Add a <%@ Reference %> directive to the top of the Web Form along with the Control attribute for the WebUserControl1.ascx file.
• C. Add a <%@ Register %> directive to the top of the Web Form along with the Assembly, Namespace, and TagPrefix attributes for the WebUserControl1 class.
• D. Add a <%@ Reference %> directive to the top of the Web Form along with the virtualPath attribute for the WebUserControl1 class.

You create a Web Form. The Web Form uses the FormView control to enable a user to edit a record in the
database.
When the user clicks the Update button on the FormView control, the application must validate that the
user has entered data in all of the fields.
You need to ensure that the Web Form does not update if the user has not entered data in all of the fields.
Which code segment should you use?

• A. Cancel = true; return; } } }
• B. protected void FormView1_ItemUpdated(object sender, FormViewUpdatedEventArgs e) { foreach (DictionaryEntry entry in e.NewValues) { if (entry.Value.Equals("")) {
• C. protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e) { foreach (DictionaryEntry entry in e.Keys) { if (entry.Value.ToString() == System.String.Empty) {
• D. protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e) { foreach (DictionaryEntry entry in e.NewValues) { if (entry.Value.Equals("")) {
• E. KeepInEditMode = true; return; } } }
• F. protected void FormView1_ItemUpdated(object sender, FormViewUpdatedEventArgs e) { foreach (DictionaryEntry entry in e.Keys) { if (entry.Value.ToString() == System.String.Empty) {
• G. KeepInEditMode = true; return; } }
  }
• H. Cancel = true; return; } } }
