Microsoft PRO: Design & Develop Wndws Apps Using MS .NET Framework 4 - 070-518무료 덤프문제 풀어보기
You are designing an n-tier solution that includes a Windows Presentation Foundation (WPF) client application. The WPF application connects to a middle-tier server that runs the data access layer.
The data access layer connects to a Microsoft SQL Server 2008 database and to a mainframe-based database.
The mainframe-based database will be replaced in one year.
You have the following requirements:
---
Centrally manage all database connections.
Minimize changes to the code base when the database is replaced.
Ensure that the WPF application will not need to be redeployed when the database
is replaced.
You need to recommend an approach for designing the data access layer.
What should you recommend?

You are developing a Windows application by using Microsoft .NET Framework 4, Microsoft Visual Studio 2010, and Microsoft SQL Server 2008.
New features that require changes to be made to the database schema are added to the application every week.
You need to ensure that the changes made to the database schema do not require the application to be recompiled.
Which two actions should you perform? (Each correct answer presents part of the solution.
Choose two.)

You are developing an application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
You plan to use Microsoft Sync Framework to synchronize the data stored in a local Microsoft SQL Server Compact Edition database with the data stored in a centralized SQL Server 2008 database.
Four columns are added to each table involved in the synchronization process to track changes to the database. You add the following four columns to the database table.
Users report that the synchronization process is not always successful. You need to ensure that the application synchronizes data successfully. What should you do?

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.

You are reviewing an existing Windows application that uses .NET Framework 4.
When the user clicks a button, the application sequentially processes thousands of image files contained in a directory.
The user interface becomes unresponsive while the application processes the files.
You have the following requirements:
Modify the button's click event.
Increase application throughput by processing multiple image files concurrently.
Ensure that the user interface remains responsive while the application processes
the image files.
You need to recommend an approach for meeting the requirements.

You are designing a Windows Presentation Foundation (WPF) application. The WPF application contains code that will be executed by both full trust callers and partial trust callers.
The WPF application code does not have the AllowPartialTrustCallers attribute set.
You have the following requirements:
- The application security settings must allow partial trust callers to create and write
to a file.
- Users must have access only to files that they create and not to files created by other users.
You need to recommend a location for storing each user's files.

You are designing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The business logic layer of the application is implemented by using Windows Communication Foundation (WCF).
You create a duplex bidirectional WCF service that contains a single operation. The service operation sends the result back to the client application by using a two-way callback operation.
You plan to design a service interaction strategy.
You need to ensure that deadlocks are prevented.
