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

1. You use Microsoft Visual Studio 2010 and Microsoft Entity Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database. You use the ADO.NET LINQ to SQL model
to retrieve data from the database.
The applications contains the Category and Product entities as shown in the following exhibit:

You need to ensure that LINO to SQL executes only a single SQL statement against the database. You also need to ensure that the query returns the list of categories and the list of products.
Which code segment should you use?
Exhibit:

A) using (NorthwindDataContext dc = new NorthwindDataContext()) { dc.ObjectTrackingEnabled = false;
var categories = from c in dc.Categories
select c;
foreach (var category in categories) { Console.WriteLine("{0} has {1} products", category.CategoryName, category.Products.Count); } }
B) using (NorthwindDataContext dc = new NorthwindDataContext()) { dc.DeferredLoadingEnabled = false;
DataLoadOptions dlOptions = new DataLoadOptions();
dlOptions.AssociateWith<Category>(c => c.Products);
dc.LoadOptions = dlOptions;
var categories = from c in dc.Categories
select c;
foreach (var category in categories) { Console.WriteLine("{0} has {1} products", category.CategoryName, category.Products.Count); } }
C) using (NorthwindDataContext dc = new NorthwindDataContext()) { dc.DeferredLoadingEnabled = false;
DataLoadOptions dlOptions = new DataLoadOptions();
dlOptions.LoadWith<Category>(c => c.Products);
dc.LoadOptions = dlOptions;
var categories = from c in dc.Categories select c;
foreach (var category in categories) { Console.WriteLine("{0} has {1} products", category.CategoryName, category.Products.Count); } }
D) using (NorthwindDataContext dc = new NorthwindDataContext()) { dc.DeferredLoadingEnabled = false;
var categories = from c in dc.Categories
select c;
foreach (var category in categories) { Console.WriteLine("{0} has {1} products", category.CategoryName, category.Products.Count); } }

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application. You use the ADO.NET Entity Framework Designer to model entities as shown in the following diagram.

You create an ObjectContext instance named objectContext1 and use it to create a SalesPerson instance
named person1.
You create an ObjectContext instance named objectContext2 and use it to create a SalesTerritory instance
named territory1.
You need to create and persist a relationship between person1 and terrotory1. What should you do?

A) Detach person1 from objectContext1. Attach person1 to objectContext2. Set the SalesTerritory property of person1 to territory1. Call SaveChanges on objectContext2.
B) Detach person1 from objectContext1. Detach territory1 from objectContext2. Set the SalesTerritory property of person1 to territory1. Call Refresh on both objectContext1 and objectContext2.
C) Attach person1 to objectContext2. Detach territory1 from objectContext2. Set the SalesTerritory property of person1 to territory1. Call Refresh on objectContext1.
D) Attach person1 to objectContext2. Attach territory1 to objectContext1. Set the SalesTerritory property of person1 to territory1. Call SaveChanges on both objectContext1 and objectContext2.

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application uses the ADO.NET Entity Framework to model entities. You create an entity as shown in
the following code fragment.
<EntityType Name="ProductCategory">
<Key>
<PropertyRef Name="ProductCategoryID" />
</Key>
<Property Name="ProductCategoryID" Type="int" Nullable="false" StoreGeneraedPattern="Identity" />
<Property Name="ParentProductCategoryID" Type="int" />
<Property Name="Name" Type="nvarchar" Nullable="false" MaxLength="50" />
...
</EntityType>
You need to provide two entity-tracking fields:
-rowguid that is automatically generated when the entity is created
-ModifiedDate that is automatically set whenever the entity is updated. Which code fragment should you add to the .edmx file?

A) <Property Name="rowguid" Type="uniqueidentifier" Nullable="false" StoreGeneratedPattern="Computed"/> <Property Name="ModifiedDate" Type="timestamp" Nullable="false" StoreGeneratedPattern="Identity"/>
B) <Property Name="rowguid" Type="uniqueidentifier" Nullable="false" StoreGeneratedPattern="Computed"/> <Property Name="ModifiedDate" Type="timestamp" Nullable="false" StoreGeneratedPattern="Computed"/>
C) <Property Name="rowguid" Type="uniqueidentifier" Nullable="false" StoreGeneratedPattern="Identity"/> <Property Name="ModifiedDate" Type="timestamp" Nullable="false" StoreGeneratedPattern="Computed"/>
D) <Property Name="rowguid" Type="uniqueidentifier" Nullable="false" StoreGeneratedPattern="Identity"/> <Property Name="ModifiedDate" Type="timestamp" Nullable="false" StoreGeneratedPattern="Identity"/>

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that
uses the Entity Framework.
The application defines the following Entity Data Model.

Within the .edmx file, the following function is defined:
<Function Name="Round" ReturnType="Decimal"> <Parameter Name="val" Type="Decimal" /> <DefiningExpression>
CAST(val as Edm.Int32) </DefiningExpression> </Function>
The application includes the following LINQ query.
var query = from detail in context.SalesOrderDetails select detail.LineTotal.Round();
You need to ensure that the Round function executes on the database server when the query is executed. Which code segment should you use?

A) public static class DecimalHelper
{
[EdmFunction("Edm", "Round")]
public static Decimal Round(this Decimal Amt)
{
throw new NotSupportedException();
}
}
B) public static class DecimalHelper
{
[EdmFunction("SqlServer", "Round")]
public static Decimal Round(this Decimal Amt)
{
throw new NotSupportedException();
}
}
C) public static class DecimalHelper
{
public static Decimal Round(this Decimal input)
{
return (Decimal)(Int32)input;
}
}
D) public static class DecimalHelper
{
public static SqlDecimal Round(this Decimal input)
{
return SqlDecimal.Round(input, 0);
}
}

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application. You use the Entity Framework Designer to create an Entity Data Model using model-first development.
The database has the following requirements:
-each table must have a datetime column named time_modified
-each table requires a trigger that updates the value of the time_modified column when a row is inserted or updated
You need to ensure that the database script that is created by using the Generate Database From Model
option meets the requirements.
What should you do?

A) Create a new T4 template, and set the DDL Generation template to the name of the new template.
B) Add a new entity named time_modified to the model, and modify each existing entity so that it inherits from the new entity.
C) Add a DateTime property named time_modified to each entity in the model and set the property's StoreGeneratedPattern to Computed.
D) Create a new Windows Workflow Foundation workflow, and set Database Generation Workflow to the name of the new workflow.
