Microsoft 70-518

Microsoft PRO: Design & Develop Wndws Apps Using MS .NET Framework 4 認定 70-518 試験問題:

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

2. 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) Integration testing
B) Component stress testing
C) Buffer overflow testing
D) Stress testing

3. You are developing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application will consume a Windows Communication Foundation (WCF) service. The WCF service will provide data to the application.
You plan to use the ADO.NET Entity Framework to create a data model that will be used by the application.
Another development team makes changes to the WCF service data contract.
You need to ensure that changes made to the WCF service data contract do not require the application to be recompiled.
What should you do?

A) Create a conceptual model and a storage model based on the existing version of the WCF service.
B) Create a storage model based on the business model. Use a class generated from the storage model for programming.
C) Create a storage model based on the schema of the existing WCF service. Update the mapping file when the new version of the WCF service is available.
D) Create a conceptual model based on the business model. Use a class generated from the conceptual model for programming. Update the mapping file when the new version of the WCF service is available.

4. You are creating a Windows Presentation Foundation (WPF) application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application will consist of several data entry forms. Each data entry form requires a user to enter phone numbers and addresses.
You need to design a solution that promotes code reusability.
What should you do?

A) Create a new user control and reference it on each data entry form.
B) Create a new merged resource dictionary and reference it from each data entry form.
C) Use the same style resource for each data entry form.
D) Add multiple text boxes for each data entry form.

5. You are designing a Windows Presentation Foundation (WPF) application.
The WPF application must run against either Microsoft SQL Server 2008 or a third-party
database system without duplicating data access logiC.
You need to recommend a data access technology.
What should you recommend?

A) ADO.NET using DataSet objects and SqlDataReader objects
B) LINQ to Entities
C) ADO.NET using DataSet objects and SqIDataAdapter objects
D) LINQ to SQL
