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

1. You are adding a process to the application. The process performs the following actions:
1.Opens a ContosoEntities context object named context1.
2.Loads a Part object into a variable named part1.
3.Calls the Dispose() method on context1.
4.Updates the data in part1.
5.Updates the database by using a new ContosoEntities context object named context2.
You need to update the database with the changed data from part1. What should you do?

A) Add the following code segment before calling SaveChanges() on context2:
context2.Attach(part1);
context2.ApplyCurrentValues("Parts", part1);
B) Add the following code segment before calling SaveChanges() on context2:
context2.ApplyOriginalValues("Parts", part1);
C) Add the following code segment before calling SaveChanges() on context2:
context2.Attach(part1);
context2.ObjectStateManager.ChangeObjectState(part1,
System.Data.EntitySate.Modified);
D) Add the following code segment before calling SaveChanges() on context2:
context2.ApplyCurrentValues("Parts", part1);

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 database. You create the classes shown in the following exhibit:

You add the following code segment to the application. (Line numbers are included for reference only.)
01 public void QueryPlayers (List <League> leagues) {
02 ...
03 }
You create a LINQ query to retrieve a collection of Player objects.
You need to ensure that the collection includes all the players from each team and every league. Which
code segment should you insert at line 02?

A) var query = leagues.Select(l => l.Teams.Select(t => t.Players));
B) var query = leagues.SelectMany(l => l.Teams.Select(t => t.Players));
C) var query = leagues.Select(l => l.Teams.SelectMany(t => t.Players));
D) var query = leagues.SelectMany(l => l.Teams.SelectMany(t => t.Players));

3. The user interface requires that a paged view be displayed of all the products sorted in alphabetical order.
The user interface supplies a current starting index and a page size in variables named startIndex and
pageSize of type int.
You need to construct a LINQ expression that will return the appropriate Parts from the database from an
existing
ContosoEntities context object named context. You begin by writing the following expression:
context.Parts
Which query parts should you use in sequence to complete the expression?
(To answer, move the appropriate actions from the list of actions to the answer area and arrange them in
the correct order.)

A) .Take(pageSize);
B) .Take(startIndex)
C) .OrderBy(x => x.Name)
D) .Skip(pageSize)
E) .Skip(startIndex)

4. You are developing a new feature that displays an auto-complete list to users as the type color names. You
have an
existing ContosoEntities context object named contex.
To support the new feature you must develop code that will accept a string object named text containing a
user's
partial input and will query the Colors database table to retrieve all color names that begin with that input.
You need to create an Entity SQL (ESQL) query to meet the requirement.
The query must not be vulnerable to a SQL injection attack. Which code segment should you use?

A) var parameter = new ObjectParameter("text", text + "%"); var result = context.CreateQuery<string>(
"SELECT VALUE (c.Name) FROM Colors AS c WHERE c.Name LIKE '@text'", parameter);
B) var parameter = new ObjectParameter("text", text + "%");
var result = context.CreateQuery<string>( "SELECT (c.Name) FROM Colors AS c WHERE c.Name LIKE @text", parameter);
C) var parameter = new ObjectParameter("text", HttpUtility.HtmlEncode(text) + "%"); var result = context.CreateQuery<string>(
"SELECT (c.Name) FROM Colors AS c WHERE c.Name LIKE '@text'@, parameter);
D) var parameter = new ObjectParameter("text", text + "%");
var result = context.CreateQuery<string>(
"SELECT VALUE (c.Name) FROM Colors AS c WHERE c.Name LIKE @text",
parameter);

5. You need to ensure that an exception is thrown when color names are set to less than two characters. What should you do?

A) Add the following method to the Color partial class in Model\Color.cs:
protected overrride void OnPropertyChanged(string property)
{
if (property == "Name" && this.Name.Length < 2)
throw new ArgumentOutOfRangeException("Name must be at least two
characters");
}
B) Add the following method to the Color partial class in Model\Color.cs:
protected overrride void OnPropertyChanging(string property)
{
if (property == "Name" && this.Name.Length < 2)
throw new ArgumentOutOfRangeException("Name must be at least two
characters");
}
C) Add the following code segment to the ContosoEntities partial class in Model\ContosoEntities.cs:
public override in SaveChanges(System.Data.Objects.SaveOptions options)
{
var changes = this.ObjectStateManager.GetObjectSateEntries
(System.Data.EntityState.Added);
foreach (var change in changes)
{
if (change.Entity is Color) if (((Color)change.Entity.Name.Length < 2) throw new ArgumentException ("Name too short");
}
return base.SaveChanges(options);
}
D) Add the following attribute to the Name property of the Color class in the entity designer file:
[StringLength(256, MinimumLength = 2)]
