Microsoft 70-516 Exam Syllabus Topics:

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

1. How do you define a WCF Data Service query to grab the first 10 records. Options are something like:

A) DataServiceQuery<Order> selectedOrders = context.Orders.AddQueryOption("$filter", "10");
B) DataServiceQuery<Order> selectedOrders = context.Orders.AddQueryOption("$top", "10");
C) DataServiceQuery<Order> selectedOrders = context.Orders.AddQueryOption("$select", "10");
D) DataServiceQuery<Order> selectedOrders = context.Orders.AddQueryOption("$expand", "10");

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. You create stored procedures by using the following signatures:
CREATE procedure [dbo].[Product_Insert](@name varchar(50),@price float)
CREATE procedure [dbo].[Product_Update](@id int, @name varchar(50), @price
float)
CREATE procedure [dbo].[Product_Delete](@id int)
CREATE procedure [dbo].[Order_Insert](@productId int, @quantity int)
CREATE procedure [dbo].[Order_Update](@id int, @quantity int,@originalTimestamp
timestamp)
CREATE procedure [dbo].[Order_Delete](@id int)
You create a Microsoft ADO.NET Entity Data Model (EDM) by using the Product and Order entities as shown in the exhibit:

You need to map the Product and Order entities to the stored procedures. To which two procedures should
you add the @productId parameter?
(Each correct answer presents part of the solution. Choose two.)

A) Product_Delete
B) Product_Update
C) Order_Delete
D) Order_Update

3. You have been assigned the task of writing code that executes an Entity SQL query that returns entity type
objects that contain a property of a complex type.
(Line numbers are included for reference only.)
01 using (EntityCommand cmd = conn.CreateCommand())
02 {
03 cmd.CommandText = esqlQuery;
04 EntityParameter param = new EntityParameter();
05 param.ParameterName = "id";
06 param.Value = 3;
07 cmd.Parameters.Add(param);
08 using (EntityDataReader rdr = cmd.ExecuteReader
(CommandBehavior.SequentialAccess))
09 {
10 while (rdr.Read())
11 {
12 ...
13 Console.WriteLine("Email and Phone Info:");
14 for (int i = 0; i < nestedRecord.FieldCount; i++)
15 {
16 Console.WriteLine(" " + nestedRecord.GetName(i) + ": " +
nestedRecord.GetValue(i));
17 }
18 }
19 }
20 }
Which code segment should you insert at line 12?

A) DbDataRecord nestedRecord = rdr["EmailPhoneComplexProperty"] as DbDataRecord;
B) DataSet nestedRecord = rdr["EmailPhoneComplexProperty"] as ComplexDataSet
C) ComplexDataRecord nestedRecord = rdr["EmailPhoneComplexProperty"]
D) DbDataRecord nestedRecord = rdr["EmailPhoneComplexProperty"]

4. You use Microsoft .NET Framework 4.0 to develop an application that uses LINQ to SQL. The LINQ to SQL
model contains the Product entity.
A stored procedure named GetActiveProducts performs a query that returns the set of active products from
the database.
You need to invoke the stored procedure to return the active products, and you must ensure that the LINQ
to SQL context can track changes to these entities. What should you do?

A) Select the Product entity, view the entity's property window, and change the Source for the entity to GetActiveProducts.
B) Navigate to the GetActiveProducts stored procedure in Server Explorer, and drag the procedure onto the Product entity in the LINQ to SQL model designer surface.
C) Add a property named GetActiveProducts to the Product entity.
D) Select the Product entity, view the entity's property window, and change the Name for the entity to GetActiveProducts.

5. The database contains orphaned Color records that are no longer connected to Part records.
You need to clean up the orphaned records. You have an existing ContosoEntities context object named
context.
Which code segment should you use?

A) context.Colors.TakeWhile(c => !c.Parts.Any()); context.SaveChanges();
B) context.Colors.ToList().RemoveAll(c => !c.Parts.Any()); context.SaveChanges();
C) var unusedColors = context.Colors.Where(c => !c.Parts.Any()); context.DeleteObject(unusedColors); context.SaveChanges();
D) var unusedColors = context.Colors.Where(c => !c.Parts.Any()).ToList(); foreach (var unused in unusedColors){
context.DeleteObject(unused)
}
context.SaveChanges();
