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

Question 1

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Windows
Communication
Foundation (WCF) Data Services service. You deploy the data service to the following URL: http://
contoso.com/Northwind.svc.
You add the following code segment. (Line numbers are included for reference only.)
01 var uri = new Uri(@"http://contoso.com/Northwind.svc/");
02 var ctx = new NorthwindEntities(uri);
03 var categories = from c in ctx.Categories select c;
04 foreach (var category in categories) {
05 PrintCategory(category);
06 ...
07 foreach (var product in category.Products) {
08 ...
09 PrintProduct(product);
10 }
11 }
You need to ensure that the Product data for each Category object is lazy-loaded. What should you do?

A. Add the following code segment at line 06:
ctx.LoadProperty(category, "Products");
B. Add the following code segment at line 08:
ctx.LoadProperty(product, "*");
C. Add the following code segment at line 08:
var strprdUri= string.format("Products?$filter=CategoryID eq {0}",
category.CategoryID);
var prodcutUri = new Uri(strPrd, UriKind.Relative);
ctx.Execute<Product>(productUri);
D. Add the following code segment at line 06:
var strPrdUri = string.Format("Categories({0})?$expand=Products",
category.CategoryID);
var productUri = new Uri(strPrdUri, UriKind.Relative);
ctx.Execute<Product>(productUri);

Question 2

You use Microsoft .NET Framework 4.0 to develop an ASP.NET 4 Web application.
You need to encrypt the connection string information that is stored in the web.config file. The application is
deployed to multiple servers.
The encryption keys that are used to encrypt the connection string information must be exportable and
importable on all the servers.
You need to encrypt the connection string section of the web.config file so that the file can be used on all of
the servers.
Which code segment should you use?

A. Configuration config = WebConfigurationHanager.OpenWebConfiguration ("~") ; ConnectionStringsSection section = (ConnectionStringsSection)config.GetSection ("connectionStrings") ; section.Sectionlnformation.ProtectSection("DpapiProtectedConfigurationProvider"); config.Save ();
B. Configuration config = WebConfigurationManager.OpenMachineConfiguration("~"); ConnectionStringsSection section = (ConnectionStringsSection)config.GetSection("connectionStrings"); section.Sectionlnformation.ProtectSection("RsaProtectedConfigurationProvider'*); config.Save();
C. Configuration config = WebConfigurationManager.OpenWebConfiguration("~") ; ConnectionStringsSection section = (ConnectionStringsSection)config.GetSection("connectionStrings"); section.Sectionlnformation.ProtectSection("RsaProtectedConfigurationProvider"); config.Save();
D. Configuration config = WebConfigurationManager.OpenMachineConfiguration ("~") ; ConnectionStringsSection section = (ConnectionStringsSection)config.GetSection ("connectionStrings") ; section.Sectionlnformation.ProtectSection("DpapiProtectedConfigurationProvider"); config.Save () ;

Question 3

You use Microsoft Visual Studio 2010 and .NET Framework 4.0 to develop an application.
You use entity Framework Designer to create an Entity Data Model from an existing database by using the
Generate From Database wizard.
The model contains an entity type named Product. The Product type requires an additional property that is
not mapped to database colomn.
You need to add the property to product. What should you do?

A. Add the property in a partial class named Product in a new source file.
B. Create a function import with the name of property in the Entity Framework Designer.
C. Create a comlex type with the name of the property in the Entity Framework Designer.
D. Add the property in the generated class file, and select Run Custom Tool from the solution menu.

Question 4

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

Question 5

You use Microsoft .NET framework 4.0 to develop an application that connects to a Microsoft SQL Server
2008 database named AdventureWorksLT.
The database resides on an instance named INSTA on a server named SQL01.
You need to configure the application to connect to the database. Which connection string should you add
to the .config file?

A. Data Source=SQL01; Initial Catalog=INSTA; Integrated Security=true; Application Name=AdventureWorksLT;
B. Data Source=SQL01\INSTA; Initial Catalog=AdventureWorksLT; Integrated Security=true;
C. Data Source=AdventureWorksLT; Initial Catalog=SQL01\INSTA; Integrated Security=true;
D. Data Source=SQL01; Initial Catalog=AdventureWorksLT; Integrated Security=true; Application Name=INSTA;
