Microsoft 070-523 Value Pack (Frequently Bought Together)

You are creating a Windows Communication Foundation (WCF) service that implements operations in a
RESTful manner.
You need to add a delete operation.
You implement the delete method as follows.
string void DeleteItems(string id);
You need to configure WCF to call this method when the client calls the service with the HTTP DELETE
operation. What should you do?

• A. Add the HttpDelete attribute to the operation.
• B. Add the WebInvoke(UriTemplate = "/Items/{id}",Method="DELETE") attribute to the operation.
• C. Replace the string parameter with a RemovedActivityAction parameter.
• D. Replace the return type with RemovedActivityAction.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. The application uses DataContexts to query the database. You create a function that meets the following requirements: "Updates the Customer table on the database when a customer is marked as deleted. "Updates the related entries in other tables (CustomerAddress, CustomerContacts) by marking them as deleted. "Prevents consumer code from setting the Deleted column's value directly. You need to ensure that the function verifies that customers have no outstanding orders before they are marked as deleted. You also need to ensure that existing applications can use the update function without requiring changes in the code. What should you do?

• A. Override the Update operation of the DataContext object.
• B. Override the Delete operation of the DataContext object.
• C. Add new entities to the DataContext object for the Customers and Orders tables.
• D. Modify the SELECT SQL statement provided to the DataContext object to use an INNER JOIN between the Customer and Orders tables.

You are designing a data access service backed by Microsoft SQL Server. Other developers will use your
service as a third-party service.
You have the following requirements:
*To reduce maintenance cost, you must write the minimal amount of code required for fulfilling the goals.
*The service must function with Microsoft and non-Microsoft technologies.
*The service must implement the WS-Security standards.
You need to design the service to meet the requirements.
Which approach should you recommend?

• A. Use SQL Server XML Web services.
• B. Use a WCF service with multiple bindings.
• C. Use an ASP.NET Web service.
• D. Use an .ashx file to return an XML response over HTTPS.

You are implementing an ASP.NET Web page.
You need to add a text box that allows only values between 1 and 10, inclusive, to be submitted. Which two
code segments should you use? (Each correct answer presents part of the solution. Choose two.)

• A. <script type="text/javascript"> function validate_value(obj, args) { return (args.Value >= 1 && args.Value <= 10); } </script>
• B. <asp:TextBox ID="txt1" runat="server" /> <asp:CustomValidator ID="val1" runat="server" ControlToValidate="txt1" ClientValidationFunction="validate_value" ErrorMessage="Value invalid" />
• C. <script type="text/javascript"> function validate_value(obj, args) { args.IsValid = (args.Value >= 1 && args.Value <= 10); } </script>
• D. <asp:TextBox ID="txt1" runat="server" onChange="validate_value(this, args)" />

You are implementing an ASP.NET application. The application includes a Person class with property Age. You add a page in which you get a list of Person objects and display the objects in a GridView control. You need to add code so that the GridView row is highlighted in red if the age of the person is less than 18. Which GridView event should you handle?

• A. RowEditing
• B. RowCommand
• C. RowDataBound
• D. RowUpdated
