Microsoft UPG:Transition MCPD.NET Frmwrk 3.5 Web Dev to 4 Web Dev Sample Questions:

1. You are consuming a Windows Communication Foundation (WCF) service in an ASP.NET Web application. The service interface is defined as follows. [ServiceContract] public interface ICatalog {
[OperationContract]
[WebGet(UriTemplate = "/Catalog/Items/{id}",
ResponseFormat = WebMessageFormat.Json)]
string RetrieveItemDescription(int id); } The service is hosted at /Catalog.svc. You need to call the service using jQuery to retrieve the description of an item as indicated by a variable named itemId. Which code segment should you use?

A) $.get(String.format("/Catalog.svc/Catalog/Items/{0}", itemId), null, function (data) {
...
},
"xml");
B) $.get(String.format("/Catalog.svc/Catalog/Items/id={0}", itemId),
null,
function (data) {
...
},
"json");
C) $.get(String.format("/Catalog.svc/Catalog/Items/?id={0}", itemId) null, function (data) {
...
},
"javascript");
D) $.get(String.format("/Catalog.svc/Catalog/Items/{0}", itemId), null, function (data) {
...
},
"json");

2. You are designing a user input form that is part of an ASP.NET Web Forms application. You need to ensure that users cannot attack the Web server by submitting invalid data. Which approach should you recommend?

A) Write an onSubmit JavaScript handler that validates all form input.
B) Write an OnClick method for the Submit button that rejects form submissions that contain invalid data.
C) Install a certificate on the Web server, and force all Web traffic to use SSL.
D) Write an onSubmit JavaScript handler that URL-encodes all data that is passed to the server.

3. You use Microsoft Visual Studio 2010, Microsoft Sync Framework, and Microsoft .NET Framework 4 to
create an application. You have a ServerSyncProvider connected to a Microsoft SQL Server database. The
database is hosted on a Web server. Users will use the Internet to access the Customer database through
the ServerSyncProvider. You write the following code segment. (Line numbers are included for reference
only.)
01SyncTable customerSyncTable = new SyncTable("Customer");
02customerSyncTable.CreationOption = TableCreationOption. UploadExistingOrCreateNewTable;
03
04customerSyncTable.SyncGroup = customerSyncGroup;
05 this.Configuration.SyncTables.Add(customerSyncTable);
You need to ensure that the application meets the following requirements: "Users can modify data locally
and receive changes from the server. "Only changed rows are transferred during synchronization. Which
code segment should you insert at line 03?

A) customerSyncTable.SyncDirection = SyncDirection.Snapshot;
B) customerSyncTable.SyncDirection = SyncDirection.DownloadOnly;
C) customerSyncTable.SyncDirection = SyncDirection.Bidirectional;
D) customerSyncTable.SyncDirection = SyncDirection.UploadOnly;

4. You are implementing an ASP.NET AJAX page. You add two UpdatePanel controls named pnlA and pnlB.
pnlA contains an UpdatePanel control named pnlAInner in its content template.
You have the following requirements.
?Update panels pnlA and pnlB must refresh their content only when controls that they contain cause a
postback.
?Update panel pnlAInner must refresh its content when controls in either pnlA or pnlB or pnlAInner cause a
postback.
You need to configure the panels to meet the requirements.
What should you do?

A) Set the UpdateMode of pnlA and pnlB to Always. Set the UpdateMode of pnlAInner to Conditional.
B) Set the UpdateMode of pnlA and pnlB to Always. Set the UpdateMode of pnlAInner to Always, and add AsyncPostBackTrigger elements to its Triggers element for every control in pnlB.
C) Set the UpdateMode of pnlA and pnlB to Conditional. Set the UpdateMode of pnlAInner to Conditional, and add AsyncPostBackTrigger elements to its Triggers element for every control in pnlA.
D) Set the UpdateMode of pnlA and pnlB to Conditional. Set the UpdateMode of pnlAInner to Always.

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application uses the ADO.NET Entity Framework to manage customer and related order records. You add a new order for an existing customer. You need to associate the Order entity with the Customer entity. What should you do?

A) Use the AddObject method of the ObjectContext to add both Order and Customer entities.
B) Set the Value property of the EntityReference of the Order entity.
C) Use the Attach method of the ObjectContext to add both Order and Customer entities.
D) Call the Add method on the EntityCollection of the Order entity.
