Microsoft 70-516 Exam Syllabus Topics:

Microsoft TS: Accessing Data with Microsoft .NET Framework 4 Sample Questions:

1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to develop an application. A file named books.xml contains the following XML.
<bib>
<book title="Programming in Unix" year="1992">
<author>Author1</author>
<author>Author2</author>
<author> Author 3 </author>
</book> </bib>
The application must generate an XML result that contains an XML element named BookTitle for each
book. The text content of the element must contain the title of the book.
You need to create a query that generates the new XML result. What should you do?

A) XDocument document = XDocument.Load("books.xml");
var query = from node in document.DescendantNodes()
where node.ToString() == "book"
select new XElement("BookTitle", node.ToString());
B) XDocument document = XDocument.Load("books.xml");
var query = from node in document.Descendants()
where node.Name.LocalName == "book"
select new XElement("BookTitle").Value = node.FirstAttribute.Value;
C) XDocument document = XDocument.Load("books.xml");
var query = from node in document.Descendants()
where node.Name.LocalName == "book"
select new XElement("BookTitle", node.FirstAttribute.Value);
D) XDocument document = XDocument.Load("books.xml");
var query = from node in document.DescendantNodes()
where node.ToString() == "book"
select new XText("BookTitle" + node.ToString());

2. You use Microsoft .NET Framework 4.0 to develop an application that uses WCF Data Services to persist entities from the following Entity Data Model.

You create a new Blog instance named newBlog and a new Post instance named newPost as shown in the
following code segment.
(Line numbers are included for reference only.)
01 Blog newBlog = new Blog();
02 Post newPost = new Post();
03 ....
04 Uri serviceUri = new Uri("...");
05 BlogsEntities context = new BlogsEntities(serviceUri);
06 ....
You need to ensure that newPost is related to newBlog through the Posts collection property and that
newPost and newBlog are sent to the service.
Which code segment should you insert at line 06?

A) newBlog.Posts.Add(newPost); context.UpdateObject(newBlog); context.UpdateObject(newPost); context.SaveChanges(SaveChangesOptions.Batch);
B) context.AttachLink(newBlog, "Posts", newPost); context.SaveChanges(SaveChangesOptions.Batch) ;
C) newBlog.Posts.Add(newPost); context.AddToBlogs(newBlog); context.AddToPosts(newPost); context.SaveChanges(SaveChangesOptions.Batch);
D) newBlog.Posts.Add(newPost); context.AttachTo("Blogs", newBlog); context.AttachTo("Posts", newPost); context.SaveChanges(SaveChangesOptions.Batch);

3. You add a table to the database to track changes to part names. The table stores the following row values:
-the username of the user who made the change
-a part ID
-the new part name
-a DateTime value
You need to ensure detection of unauthorized changes to the row values.
You also need to ensure that database users can view the original row values.

A) Use System.Security.Cryptography.DES to encrypt all the row values using an encryption key held by the application.
B) Add a column named hash. Use System.Security.Cryptography.MD5 to create an MD5 hash of the row values, and store in the hash column.
C) Use System.Security.Cryptography.RSA to encrypt all the row values. Publish only the key internally.
D) Add a column named signature. Use System.Security.Cryptography.RSA to create a signature for all of the row values. Store the signature in the signature column. Publish only the public key internally.

4. You use Microsoft .NET Framework 4.0 to develop an application that connects to two separate Microsoft
SQL Server 2008 databases.
The Customers database stores all the customer information, and the Orders database stores all the order
information.
The application includes the following code. (Line numbers are included for reference only.)
01 try
02 {
03 conn.Open();
04 tran = conn.BeginTransaction("Order");
05 SqlCommand cmd = new SqlCommand();
06 cmd.Connection = conn;
07 cmd.Transaction = tran;
08 tran.Save("save1");
09 cmd.CommandText = "INSERT INTO [Cust].dbo.Customer " + "(Name,
PhoneNumber) VALUES ('Paul Jones', " + "'404-555-1212')";
10 cmd.ExecuteNonQuery();
11 tran.Save("save2");
12 cmd.CommandText = "INSERT INTO [Orders].dbo.Order " + "(CustomerID)
VALUES (1234)";
13 cmd.ExecuteNonQuery();
14 tran.Save("save3");
15 cmd.CommandText = "INSERT INTO [Orders].dbo." + "OrderDetail (OrderlD,
ProductNumber) VALUES" + "(5678, 'DC-6721')";
16 cmd.ExecuteNonQuery();
17 tran.Commit();
18 }
19 catch (Exception ex)
20 {
21 ...
22 }
You run the program, and a timeout expired error occurs at line 16. You need to ensure that the customer
information is saved in the database.
If an error occurs while the order is being saved, you must roll back all of the order information and save the
customer information.
Which line of code should you insert at line 21?

A) tran.Rollback();
B) tran.Rollback(); tran.Commit();
C) tran.Rollback("save2"); tran.Commit();
D) tran.Rollback("save2");

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The configuration file contains the following code segment.
<configuration> <connectionStrings> <add name="AdventureWorksLT" connectionString="DataSource=SQL01;InitialCatalog=AdventureWorksLT; IntegratedSecurity=True;" providerName="System.Data.SqlClient"/> </connectionStrings> </configuration>
You need to retrieve the connection string named AdventureWorksLT from the configuration file. Which line of code should you use?

A) varconnectionString=ConfigurationManager.ConnectionStrings["AdventureWorksLT"].Name;
B) varconnectionString=ConfigurationManager.AppSettings["AdventureWorksLT"];
C) varconnectionString=ConfigurationManager.ConnectionStrings["AdventureWorksLT"].ConnectionString;
D) varconnectionString=ConfigurationSettings.AppSettings["AdventureWorksLT"];
