Microsoft 070-518 Exam Syllabus Topics:

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

1. You are designing a .NET Framework 4 solution that contains a Windows Presentation Foundation (WPF) application. The WPF application includes CPU-intensive calculations.
The calculations can be run on a separate process and can effectively be isolated from the rest of the WPF application.
You need to recommend a deployment strategy that maximizes the scalability of the calculations for each user.
What should you recommend?

A) Deploy the calculation logic as a Windows Communication Foundation (WCF) service to servers. Deploy the WPF application to the same servers.
B) Deploy the calculation logic as a separate assembly along with the WPF application to each client computer. Invoke methods in the assembly asynchronously.
C) Deploy the calculation logic as a Windows Communication Foundation (WCF) service to servers. Deploy the WPF application to each client computer.
D) Deploy the calculation logic as a separate assembly along with the WPF application to each client computer. Invoke methods in the assembly synchronously.

2. 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.)

A) Build a conceptual model and use it to access data from the business entities.
B) Modify the xml mapping file when the schema changes occur.
C) Modify the conceptual schema xml file when the schema changes occur.
D) Build a storage model and use it to access data from the business entities.

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

4. You are modifying an existing Windows Presentation Foundation (WPF) application that uses .NET Framework 4. The WPF application uses a wizard to capture data and insert the data into a database. The database includes one parent table and many child tables.
Inserting captured data in the database locks many database tables and delays application access.
You have the following requirements:
-
Reduce delays when saving datA.
--
Ensure that other application users are not blocked from reading datA. Ensure that captured data is available only after all child tables are updated.
You need to recommend an approach for inserting captured data into the database.
What should you recommend?

A) Insert captured data by using optimistic concurrency as the user completes each wizard page.
B) Insert captured data by using a single transaction as the user completes each wizard page.
C) Insert all captured data in a single transaction when the user completes the wizard.
D) Insert captured data by using non-transactional operations when the user completes the wizard.

5. 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 enterdata.
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?

A) Use System.Runtime.Caching to cache query results on the client.
B) Denormalize the data to fewer tables.
C) Create a separate data layer with caching.
D) Create stored procedures to abstract the tables.
