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

1. You are designing a distributed application that will be deployed to 5,000 users worldwide.
Servers on five continents will host the Web services and the Microsoft SQL Server 2008
databases that support the application.
You have the following requirements:
---
Collect information about all errors associated with the application.
Store and view all error information in a centralized location.
Minimize the network bandwidth required for the transfer of error information.
You need to recommend a strategy for reporting error information. Which strategy should you recommend?

A) Write error messages to the SQL Server databases. Synchronize the databases by using merge replication.
B) Write error messages to the SQL Server databases. Synchronize the databases by using transactional replication.
C) Write error messages to the event logs on the local computers. Use Windows Management Instrumentation (WMI) to view the error information.
D) Write error messages to the event logs on the local computers. Use Windows Error Reporting to view the error information.

2. 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?

A) SQL Server stored procedures
B) Private message queues with a controller class on the middle-tier server
C) A Windows Communication Foundation (WCF) service for each operation, with a controller class on the middle-tier server
D) A routed service that uses Windows Communication Foundation (WCF) messaging

3. 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?

A) Buffer overflow testing
B) Stress testing
C) Integration testing
D) Component stress testing

4. You are designing a Windows Presentation Foundation (WPF) application. The main window of the WPF application includes two panels: panel1and panel2.
The WPF application must meet the following requirements:
- Panel2 must be enabled only after users have entered values into multiple text boxes in panel1. - The background color of panel2 must be set to a specific color based on oneof the text box values in panel1. - The background color of panel2 must be set at the same time the panel is enabled.
You need to recommend an approach for meeting the requirements.
What should you recommend?

A) Use a Command object.
B) Use a Data Template object.
C) Use Dependency properties.
D) Use a MultiDataTrigger object.

5. ---
You are designing a .NET Framework 4 solution. The solution contains a Windows Presentation Foundation (WPF) application and a Windows Communication Foundation (WCF) Web service.
The WPF application uses the WCF Web service to store data in a Microsoft SQL Server 2008 database.
You have the following requirements:
Ensure that the WPF application functions while users' computers are offline.
Minimize the time spent sending data to the WCF Web service.
Minimize disk space requirements for data storage.
You need to recommend an approach for synchronizing data between the WPF application and the database.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A) Store data in custom business objects. Serialize data locally by using custom serialization.
B) Store data in DataSet objects. Serialize data locally by using XML serialization.
C) Create a local caching solution that periodically checks for Internet connectivity and writes directly to the local data store and to the WCF Web service.
D) Create a local caching solution that periodically checks for Internet connectivity, uses local memory, and batches changes to the WCF Web service.
