Microsoft 070-515 Exam Syllabus Topics:

Microsoft TS: Web Applications Development with Microsoft .NET Framework 4 Sample Questions:

1. You are implementing a new Dynamic Data Web site.
The Web site includes a Web page that has an ObjectDataSource control named ObjectDataSource1.
ObjectDataSource1 interacts with a Web service that exposes methods for listing and editing instances of a
class named Product.
You add a GridView control named GridView1 to the page, and you specify that GridView1 should use
ObjectDataSource1 as its data source.
You then configure GridView1 to auto-generate fields and to enable editing.
You need to add Dynamic Data behavior to GridView1.
You also must ensure that users can use GridView1 to update Product instances.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Add a DynamicDataManager control to the Web page.
B) Add the following code segment to the Page_Init method of the Web page.
GridView1.EnableDynamicData(typeof(Product));
C) Add the following code segment to the Application_Start method in the Global.asax.cs file.
DefaultModel.RegisterContext(typeof (System.Web.UI.WebControls.ObjectDataSource), new ContextConfiguration() {ScaffoldAllTables = true});
D) Disable the auto-generated fields on GridView1. Add a DynamicField control for each field of the Product class.

2. You are implementing an ASP.NET Web application that retrieves data from a Microsoft SQL Server
database.
You add a page that includes the following data source control.
<asp:SqlDataSource id="sqlds" runat="server" ConnectionString="<%$ ConnectionStrings:MyDB %>" SelectCommand="SELECT * FROM Companies" />
The page is accessed frequently, but the data in the database rarely changes.
You need to cache the retrieved data so that the database is not queried each time the Web page is
accessed.
What should you do?

A) Add the following attributes to the SqlDataSource control.
DataSourceMode="DataReader"
EnableCaching="True"
CacheDuration="120"
B) Add the following configuration to the <system.web/> section of the web.config file.
<caching>
<sqlCacheDependency enabled="true" pollTime="120">
<databases>
<add name="MyDBCache" connectionStringName="MyDB" /> </databases> </sqlCacheDependency>
</caching>
C) Add the following attributes to the SqlDataSource control.
DataSourceMode="DataSet"
EnableCaching="True"
CacheDuration="120"
D) Add the following configuration to the <system.web/> section of the web.config file.
<caching> <sqlCacheDependency enabled="true"> <databases> <add name="MyDBCache" connectionStringName="MyDB" pollTime="120"
/>
</databases>
</sqlCacheDependency>
</caching>

3. You create a Web page that contains the following code.
<script type="text/javascript">
var lastId = 0; </script> <div class="File">
Choose a file to upload:
<input id="File0" name="File0" type="file" /> </div> <input id="AddFile" type="button" value="Add a File" /> <input id="Submit" type="submit" value="Upload" />
You need to provide the following implementation.
Each time the AddFile button is clicked, a new div element is created.
The new div element is appended after the other file upload div elements and before the AddFile span.
Each new element has a unique identifier.
Which code segment should you use?

A) $("#AddFile").click(function () { var id = "File" + ++lastId; var item = $(".File:first").clone(true); $("input:file", item).attr({ id: id, name: id }); item.insertAfter("input[type=file]");
});
B) $("#AddFile").click(function () { var id = "File" + ++lastId; $(".File:first").clone(true).attr({ id: id, name: id }).insertBefore
("#AddFile");
});
C) $("#AddFile").click(function () {
var id = "File" + ++lastId;
});
D) $("#AddFile").click(function () { var id = "File" + ++lastId; var item = $(".File:first").clone(true); $("input:file", item).attr({ id: id, name: id }); item.insertBefore("#AddFile");
});

4. You are developing an ASP.NET web application.
The application includes the following Entity Data Model (EDM): You instantiate an ObjectContext for the EDM named context.

You need to find the total number of addresses that are associated with customers that have a non-null middle name.
Which LINQ to Entities query should you use?

A) var query = context.Customers .Where(c => c.MiddleName != null) .SelectMany(c => c.CustomerAddresses.Count();
B) var query = context.Customers .Where(c => c.MiddleName != null) .Select(c => c.CustomerAddresses.Count();
C) var query = context.Addresses .GroupBy(a => a.CustomerAddresses .Where(ca => ca.Customer.MiddleName != null)).Count();
D) var query = context.Addresses .SelectMany(a => a.CustomerAddresses.OfType<Customer>() .Where(c => c.MiddleName != null)).Count();

5. You are developing an ASP.NET web page that includes a textbox control that has ID txtDate. You need to ensure that the user enters a valid date in the text box.
Which markup should you use?

A) <asp:CompareValidator ID="valDate" runat="server" Type="Date" ControlToValidate="txtDate" Operator="DataTypeCheck"/>
B) <asp:CompareValidator ID="valDate" runat="server"
Type="Date" ControlToCompare="txtDate"
Operator="Equal"/>
C) <asp:CompareValidator ID="valDate" runat="server" Type="Date" ControlToCompare="txtDate" Operator="DataTypeCheck"/>
D) <asp:CompareValidator ID="valDate" runat="server" Type="Date" ControlToValidate="txtDate" Operator="Equal"/>
