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

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 database. The application uses the ADO.NET Entity
Framework to manage order data.
The application makes a Web service call to obtain orders from an order-tracking system.
You need to ensure that the orders are added to the local data store. Which method should you call on the
ObjectContext?

A) ApplyCurrentValues
B) AttachTo
C) AddObject
D) Attach

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that
uses the EntityFramework.
The application has an entity named Person. A Person instance named person1 and an ObjectContext
instance named model exist.
You need to delete the person1 instance. Which code segment should you use?

A) model.Detach(person1); model.SaveChanges();
B) model.ExecuteStoreCommand("Delete", new []{new ObjectParameter("Person", person1)}; model.SaveChanges();
C) model.DeleteObject(person1); model.SaveChanges();
D) model.ExecuteStoreCommand("Detach", new []{new ObjectParameter("Person", person1)}; model.SaveChanges();

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that
uses LINQ to SQL.
The application contains the following model.

Each region contains a single vendor. Customers order parts from the vendor that is located in their region.
You need to ensure that each row in the Customer table references the appropriate row from the Vendor
table.
Which code segment should you use?

A) SalesDataContext dc = new SalesDataContext("...");
var query = from v in dc.Vendors
join c in dc.Customers on v.Region equals c.Region
select new { Vendor = v, Customer = c };
foreach (var u in query){
u.Customer.VendorlD = u.Vendor.VendorlD;
}
dc.SubmitChanges();
B) SalesDataContext dc = new SalesDataContext("...");
var query = from v in dc.Vendors
join c in dc.Customers on v.VendorlD equals c.VendorID
select new { Vendor = v, Customer = c };
foreach (var u in query){
u.Customer.Region = u.Vendor.Region;
}
dc.SubmitChanges();
C) SalesDataContext dc = new SalesDataContext("...");
var query = from c in dc.Customers
join v in dc.Vendors on c.VendorlD equals v.VendorID
select new { Customer = c, Vendor = v };
foreach (var u in query){
u.Vendor.Region = u.Customer.Region;
}
dc.SubmitChanges();
D) SalesDataContext dc = new SalesDataContext("...");
var query = from c in dc.Customers
join v in dc.Vendors on c.Region equals v.Region
select new { Customer = c. Vendor = v };
foreach (var u in query){
u.Vendor.VendorlD = u.Customer.VendorID;
}
dc.SubmitChanges();

4. You are developing an ADO.NET 4.0 application that interacts with a Microsoft SQL Server 2008 server
through the SQL Server Native Client.
You create a trace DLL registry entry and you register all of the trace schemas.
You need to trace the application data access layer. Which control GUID file should you use?

A) ctrl.guid.mdac
B) ctrl.guid.msdadiag
C) ctrl.guid.adonet
D) ctrl.guid.snac10

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