最新的 MCTS 070-516 免費考試真題:

1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 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 Delete operation of the DataContext object.
B) Modify the SELECT SQL statement provided to the DataContext object to use an INNER JOIN between the Customer and Orders tables.
C) Override the Update operation of the DataContext object.
D) Add new entities to the DataContext object for the Customers and Orders tables.

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application uses the ADO.NET Entity Framework to model persistence-ignorant entities. The
application operates in a disconnected mode.
You need to ensure that changes made to local entities while the application is in the disconnected mode
are correctly persisted.
Which method should you call before persisting changes?

A) ObjectStateEntry.AcceptChanges
B) DataContext.AcceptAllChanges
C) ObjectStateEntry.SetModifiedProperty
D) ObjectContext.Refresh

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
You use the ADO.NET Entity Framework to model your entities.
You use Plain Old CLR Objects (POCO) entities along with snapshot-based change tracking. The code
accesses the POCO entities directly.
You need to ensure that the state manager synchronizes when changes are made to the object graph.
Which ObjectContext method should you call?

A) Refresh
B) DetectChanges
C) SaveChanges
D) ApplyPropertyChanges

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application contains following XML document.
<feed> <title>Products</title> <entry>
<title>Entry title 1</title>
<author>Author 1</author>
<content>
<properties>
<description>some description</description>
<notes>some notes</notes>
<comments>some comments</comments>
</properties>
</content>
</entry>
...
</feed>
You plan to add localization features to the application. You add the following code segment. (Line numbers are included for reference only.)
01 public IEnumerable <XNode> GetTextNodesForLocalization(XDocument doc) 02 {
03 ...
04 return from n in nodes
05 where n.NodeType = XmlNodeType.Text
06 select n;
07 }
You need to ensure that the GetTextNodeForLocalization method returns all the XML text nodes of the XML
document.
Which code segment should you inser at line 03?

A) IEnumerable <XNode> nodes = doc.NodesAfterSelf();
B) IEnumerable <XNode> nodes = doc.Descendants();
C) IEnumerable <XNode> nodes = doc.Nodes();
D) IEnumerable <XNode> nodes = doc.DescendantNodes();

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Windows
Communication Foundation (WCF) Data Services service.
The service connects to a Microsoft SQL Server 2008 database. The service is hosted by an Internet
Information Services (IIS) 6.0 server.
You need to ensure that applications authenticate against user information stored in the database before
the application is allowed to use the service.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Configure IIS to require Windows authentication.
B) Configure IIS to allow anonymous access.
C) Enable the WCF Authentication Service.
D) Configure IIS to require basic authentication.
E) Modify the Data Services service to use a Microsoft ASP.NET membership provider.
