You are designing a Windows Presentation Foundation (WPF) client application from which
employees will access a Web service. Business partners will access the Web service by
using proprietary client applications. You need to recommend a solution for ensuring the
integrity of data in the system. What should you recommend?

You are designing a .NET Framework 4 solution that includes a Windows Presentation
Foundation (WPF) application. The WPF application connects to a Microsoft SQL Server
2008 database. You plan to deploy the WPF application to millions of client computers. The
SQL Server database will be hosted in a data center. The WPF application will query the
database to provide type-ahead assistance as users enter data. The WPF application will
send a query after each character is entered. Each query will access multiple joined tables.
You need to recommend an approach for maximizing scalability of the solution. What should
you recommend?

You are reviewing multiple Windows Presentation Foundation (WPF) applications that
capture postal addresses. The WPF applications have different appearances and
functionality. Each WPF application uses a different control to visualize the captured
addresses. You plan to modify all WPF applications to allow developers to visualize
addresses by using a common template. You need to recommend an approach for
standardizing the visualization of captured addresses. What should you recommend?

You are evaluating an existing Windows Presentation Foundation (WPF) application. The
WPF application runs in a Web browser as a XAML browser application (XBAP). The WPF
application runs in the Intranet zone with Full Trust. A client certificate for the WPF
application has been generated. Users are unable to access the WPF application. You
locate the following message in the security log: “User has refused to grant required
permissions to the application.” Users state that they are clicking OK in all message boxes
that appear. You need to recommend an approach for ensuring that the WPF application
runs correctly on all client computers. Which two actions should you recommend? (Each
correct answer presents part of the solution. Choose two.)

An existing Windows application uses a Windows Communication Foundation (WCF) Web
service that is available only to employees. You have the following requirements: • Make the
WCF Web service available to business partners. • Enable business partners to send a
profile token. • Ensure that the currently deployed application continues to function. You
need to recommend a solution that meets the requirements. What should you recommend?

You are designing a Windows Presentation Foundation (WPF) application. The application
will be localized into multiple languages. You need to recommend an approach for preparing
the application for localization. Which two actions should you recommend? (Each correct
answer presents part of the solution. Choose two.)

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. What should you
recommend?

You are designing an n-tier Windows solution that includes a data entry application. The
solution uses Microsoft .NET Framework 4 and Microsoft SQL Server 2008. The data entry
application sends customer orders to a middle-tier server. The middle-tier server sends
orders to a set of services that perform operations on the orders. Business rules determine
which services to call and whether to run them in sequence or in parallel. The business
rules are complex and data dependent. The Windows solution must meet the following
requirements: • Optimize application performance by using dynamic load balancing. • Allow
for business rules to be changed at runtime. You need to recommend an approach that
meets the requirements. What should you recommend?

You are designing an n-tier .NET Framework 4 solution that includes a Windows
Presentation Foundation (WPF) application. You need to recommend an approach for
ensuring that the solution can support 5,000 concurrent users. What should you
recommend?

You design a Windows Presentation Foundation (WPF) application that connects to a
Microsoft SQL Server 2008 database. The WPF application becomes unresponsive at
times. When the WPF application is running, physical memory usage is between 90 percent
and 95 percent. You need to recommend a tool that will identify the memory usage
characteristics of the WPF application. Which tool should you recommend?
