Microsoft UPG:Transition MCPD.NET Frmwrk 3.5 Web Dev to 4 Web Dev Sample Questions:

1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 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="Identity"/> <Property Name="ModifiedDate" Type="timestamp" Nullable="false" StoreGeneratedPattern="Computed"/>
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="Computed"/> <Property Name="ModifiedDate" Type="timestamp" Nullable="false" StoreGeneratedPattern="Identity"/ >
D) <Property Name="rowguid" Type="uniqueidentifier" Nullable="false" StoreGeneratedPattern="Identity"/> <Property Name="ModifiedDate" Type="timestamp" Nullable="false" StoreGeneratedPattern="Identity"/ >

2. You are designing an ASP.NET Web application that displays daily sales information. The sales
information is stored in a large Microsoft SQL Server database. The database information is updated each
night. During the day, people use the Web application to display a set of standard sales reports based on
the latest database information.
The SQL queries that are required to retrieve the database information can take from 20 to 30 seconds to
execute.
You need to design the application to ensure that pages usually load in no more than 5 seconds.
Which two approaches could you recommend? (Each correct answer presents a complete solution.
Choose two.)

A) Use a control that retrieves and displays the database information.
B) Use SQL Server replication.
C) Use a service that proxies the database queries and caches the results.
D) Use AJAX to retrieve the database information.

3. You are troubleshooting an ASP.NET Web application. System administrators have recently expanded your
web farm from one to two servers. Users are periodically reporting an error message about invalid view
state.
You need to fix the problem.
What should you do?

A) Override the SavePageStateToPersistenceMedium and LoadPageStateFromPersistenceMedium methods in the page base class to serialize the view state to a local web server file.
B) Set the machineKey in machine.config to the same value on both servers.
C) Set viewStateEncryptionMode to Auto in web.config on both servers.
D) Change the session state mode to SQL Server on both servers and ensure both servers use the same connection string.

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You use
the ADO.NET Entity Framework to model your entities.
You use Plain Old CLR Objects (POCO) entities along with snapshot-based change tracking. The code
accesses the POCO entities directly.
You need to ensure that the state manager synchronizes when changes are made to the object graph.
Which ObjectContext method should you call?

A) SaveChanges
B) Refresh
C) DetectChanges
D) ApplyPropertyChanges

5. A WCF service code is implemented as follows. (Line numbers are included for reference only.)

06 <OperationContract()>
07Public Function Calculate(ByVal op1 As Double,
08ByVal op As String, ByVal op2 As Double) As Double
...
24End Function
25
26End Class
You need to increase the rate by which clients get the required response from the service.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)

A) Require the clients use threads, the Parallel Task Library, or other mechanism to issue service calls in parallel.
B) Require the clients to use async operations when calling the service.
C) Change the service behavior to the following. <ServiceBehavior( InstanceContextMode:=InstanceContextMode.Single, ConcurrencyMode:=ConcurrencyMode.Multiple)>
D) Change the service behavior to the following. <ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)>
