Microsoft 070-518 Exam Syllabus Topics:

Microsoft PRO: Design & Develop Wndws Apps Using MS .NET Framework 4 Sample Questions:

1. You are designing a Windows Presentation Foundation (WPF) application. The WPF application displays indicators to compare your company's past performance to the current day's operationsdata.
The WPF application accesses historic data from your company's data warehouse through a Web service, and accesses current data directly from a Microsoft SQL Server 2008 database.
The WPF application must meet the following requirements:
- Retrieve historic data from the data warehouse at application startup and then once per day.
- Retrieve current data from the database every five minutes, and then update the
indicators.
- Cache all retrieveddata.
- Target the .NET Framework 4 Client Profile.
You need to recommend an approach to data caching.
What should you recommend?

A) UseSystem.Web.Caching with a sliding expiration.
B) UseSystem.Web.Caching with an absolute expiration.
C) Use System.Runtime.Caching with an absolute expiration.
D) Use System.Runtime.Caching with a sliding expiration.

2. You are designing a Windows Presentation Foundation (WPF) application that accesses a business tier. The business tier is implemented as a Windows Communication Foundation (WCF) service and stores data in a Microsoft SQL Server 2008 database.
The WCF service will be accessed by external applications that do not use the .NET Framework.
You need to recommend an approach for passing data between layers.
What should you recommend?

A) Use custom .NET classes with XML serialization.
B) Use a DataSet object.
C) Use custom .NET classes with binary serialization.
D) Use the DiffGram XML format.

3. You are designing a .NET Framework 4 solution that includes a Windows Presentation Foundation (WPF) application, a Windows service, and a private assembly shared by the WPF application and by the Windows service.
The solution stores data in a local Microsoft SQL Server Compact 3.5 database. The WPF application and Windows service will each access the database directly. The solution will be installed by using Windows Installer.
You have the following requirements:
- The installer must allow users to specify the installation folders for the WPF application and for the database. - The solution must support the deployment of updates to the WPF application without restarting the Windows service.
You need to recommend an approach for installing the solution.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A) In the installer, set an environment variable that defines the database installation path.
B) Install the Windows service to a different folder from the WPF application.
C) In the installer, create a registry key that stores the WPF application installation path.
D) Install the Windows service to the same folder as the WPF application.

4. You are designing a Windows Presentation Foundation (WPF) application that connects to a data access layer on a server.
You have the following requirements for all security-related exceptions:
- Exceptions that occur in the data access layer must be handled in a single exception handler in the WPF application. - Exceptions must pass customized messages back to the WPF application.
You need to recommend an approach for creating new exception classes in the data access layer.
From which class should you inherit?

A) System.AccessViolattonException
B) System.Security.SecurityException
C) System.InvalidOperationException
D) System.ApplicationException

5. You are preparing to deploy a solution that includes a Windows Forms application and several COM components. Unsigned interop assemblies have been created for each of the COM components.
You need to recommend an approach for deploying the solution.
What should you recommend?

A) Deploy the Windows Forms application and COM components to a folder on the client computer. Deploy the interop assemblies to the Global Assembly Cache (GAC).
B) Deploy the Windows Forms application, COM components, and interop assemblies to a folder on the client computer. Register the COM components.
C) Deploy the Windows Forms application to a folder on the client computer. Deploy the COM components and interop assemblies to the Global Assembly Cache (GAC). Register the COM components.
D) Deploy the Windows Forms application and interop assemblies to a folder on the client computer. Sign the interop assemblies.
