You are packaging updates for multiple Windows Presentation Foundation (WPF) applications. Updates to the applications and to third-party control files are available. Updates to the applications have dependencies upon updates to the third-party control files. An update script is run at logon that allows only a single command to be executed. You need to package the application updates and updates to the third-party controls to ensure that they are successfully installed.
What should you do?

You have developed a Windows Forms server application.
Client applications connect to the server application to receive streaming media on demand on a single server.
Each incoming connection is launched on a separate thread, As the number of client applications increases, users report that connection attempts fail. You need to ensure that users can connect to the server application even when the number of clients increase.

What should you do?

You are developing a Windows Presentation Foundation (WPF) application. During unit testing you identify several bottlenecks by using Windows Task Manager and Windows performance Monitor.
You need to recommend a system test strategy that will meet the following requirements:

– identify major application workloads
– identify the functions of the application that are most impacted

Which testing strategy should you recommend?

You are developing a Windows Presentation Foundation (WPF) application. You need to ensure that the following requirements are met All UI elements are labled
All property values are exposed.
Keyboard navigation contains tab stops for all controls.
The application functions on high-contrast displays.

Which testing strategy should you recommend?

You are developing a Windows Presentation Foundation (WPF) application. You need to recomend a testing strategy to identify the additional hardware resources that are necessary to support future projected growth.

Which testing strategy should you recommend?

The application includes multiple Windows Workflow Foundation (WF) hosts along with thousands of instances.
The application will continue to execute over extended periods of time. You need to ensure that the performance of the application does not degrade over extended periods of time.

Which type of testing should you perform on the application?

You are design updates to the existent WPF application the connect to the MSSQL 2008. The application updates will require updates to the database. You have the following requirements:
Prevent data loss
Recover the database if the database update failure
You need to recommend a database deployment strategy. Which two actions should you recommend:

Developers required to use part of functionality of COM assembly. You must to design an interop assembly that expose COM functionality. Chose 2 as part.

Remote users have limited connectivity.
Users will not have write permissions to the local file system. You plan to design the error logging strategy for the application. You need to ensure that the application can collect error information. You also need to ensure that the errors can be analyzed from a centralized location.

What should you do?

You are designing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.

You plan to implement control caching to improve the loading time of a control. It is not required to refresh the content of the control after the application loads. The application will be compiled by using the .NET 4 client profile.

You need to ensure that the following requirements are met:
The control is reusable in multiple forms.
Data in the control is cached when the application is loaded.
