Microsoft 070-516 Exam Syllabus Topics:

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

1. You are developing a new feature in the application to display a list of all bundled products.
You need to write a LINQ query that will return a list of all bundled products. Which query expression should
you use?

A) context.Parts.Cast<Product>() .ToList() .Where(p => p.Descendants.Any(d => d is Product))
B) context.Parts.Cast<Product>() .Where(p => p.Descendants.Any(d => d is Product))
C) context.Parts.OfType<Product>() .ToList() .Where(p => p.Descendants.Any(d => d is Product))
D) context.Parts.OfType<Product>() .Where(p => p.Descendants.Any(d => d is Product))

2. 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) Add new entities to the DataContext object for the Customers and Orders tables.
B) Override the Delete operation of the DataContext object.
C) Override the Update operation of the DataContext object.
D) Modify the SELECT SQL statement provided to the DataContext object to use an INNER JOIN between the Customer and Orders tables.

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 entities. You write the following code segment. (Line numbers are included for reference only.)
01 public partial class SalesOrderDetail : EntityObject
02 {
03 partial void OnOrderQtyChanging(short value)
04 {
05 ...
06 {
07 ...
08 }
09 }
10 }
You need to find out whether the object has a valid ObjectStateEntry instance. Which code segment should you insert at line 05?

A) if (this.EntityState != EntityState.Detached)
B) if (this.EntityState != EntityState.Unchanged)
C) if (this.EntityState != EntityState.Modified)
D) if (this.EntityState != EntityState.Added)

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application contains the following XML document:
<bib> <book title="TCP/IP Illusrated" year="1994">
<author>Author1</author>
</book>
<book title="Programming in UNIX" year="1992">
<author>Author1</author>
<author>Author2</author>
<author>Author3</author>
</book>
<book title="Data on the web" year="2000">
<author>Author4</author>
<author>Author3</author>
</book> </bib>
You add the following code fragment. (Line numbers are included for reference only.)
01 public IEnumerable<XElement> GetBooks(string xml)
02 {
03 XDocument doc = XDocument.Parse(xml);
04 ...
05 }
You need to return a list of book XML element that are authored by Author1. Which code segment should you insert at line 04?

A) return doc.Element("bib").Elements() .SelectMany(el => el.Elements() .Where(e2 => e2.Equals(new XElement("author", "Author1"))));
B) return doc.Element("bib").Elements() .SelectMany(el => el.Elements() .Where(e2 => (string)e2 == "Author1"));
C) return doc.Elements("bib").Elements()
.Where(e1 => e1.Elements().Any(e2 => e2.Equals(new XElement("author", "Author1"))));
D) return doc.Elements("bib").Elements() .Where(e1 => e1.Elements().Any(e2 => (string)e2 == "Author1"));

5. 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. You use the ADO.NET Entity Framework to
model entities.
You need to add a new type to your model that organizes scalar values within an entity.
You also need to map stored procedures for managing instances of the type. What should you do?

A) 1. Add the stored procedures in the SSDL file along with a Function attribute.
2.Define a complex type in the CSDL file.
3.Map the stored procedure in the MSL file with a ModificationFunctionElement.
B) 1. Add the stored procedures in the SSDL file along with a Function attribute.
2.Define a complex type in the CSDL file.
3.Map the stored procedure in the MSL file with an AssociationEnd element.
C) 1. Use the edmx designer to import the stored procedures.
2.Derive an entity class from the existing entity as a complex type.
3.Map the stored procedure in the MSL file with an AssociationEnd element.
D) 1. Add the stored procedures in the SSDL file along with a Function attribute.
2.Derive an entity class from the existing entity as a complex type.
3.Map the stored procedure in the MSL file with a ModificationFunctionElement.
