You are designing an application by using Windows Presentation Foundation (WPF) and Microsoft NET Framework 4
The application is designed to allow novice users to enter data into a form. If a user enters invalid data into an input control, the control blinks between two colors. You need to ensure that the blinking visual feature can be applied to other controls without writing any additional code
What should you do?

You are debugging a Windows application that uses Windows Presentation Framework (WPF) and Microsoft Visual Studio 2010.
The application is deployed as an XAML browser application (XBAP). Some users report that they are not able to use the drag-and-drop functionality. You need to ensure that all users can use the drag-and-drop functionality.
What should you do?

You are creating a Windows Presentation Foundation (WPF) application by using Microsoft NET Framework 4.
You creates a photo album-browsing application.
When the user opens an album,pictures in the album are displayed in sets of 10. Pictures are obtained from a Windows Communication Foundation (WCF) service. Most of the memory of the application is allocated in the native heap. The memory usage of the application increases when new albums are opened. You need to ensure that the memory usage of the application remains within a specific range.
What should you do?

The Windows 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 wil be used by the application. Other development team members make 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?

You are developing a Windows Application.
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 2 actions should you perform?

You are designing an application in the .net framework 4.0 The application is used mostly in a disconnected scenario. The application requires offline data from a Microsoft Sql Server 2008 database. When the application connects to the network, data will be modified and synchronized. You need to ensure that the application does not access the database server directly to synchronize data when online.

Which technology should you use?

You are developing a Windows application.
The application will process data that is stored on the user’s computer.
You plan to design a data storage strategy.
You need to ensure that the following requirements are met:
+ Local data can be accessed ony by the application
+ Local data can be encrypted and compressed
+ Local data can be shared between multiple users by sending them the data file by email
+ Users must be able to open the data file directly from the email message

Which local data storage technology should you use?

You are designing a data access layer (DAL) for an application. Conflicts are occurring in the SQL Server database due to concurrent updates. You need to design a database locking strategy that meets the following requirements:
Resolves concurrent update conflicts without loss of data
Ensures that data conflicts can be resolved by users
Locks only the necessary data for updates

What should you do?

You are analyzing an application.
The application is used to maintain an inventory database and is accessed from several remote Windows client applications.
The application frequently updates multiple rows in a database table by using a DbDataAdapter object. Users report that the application runs slowly during peak business hours. When large number of records are changed by multiple users, you discover the following:
+ The CPU utilization of the client applications is normal
+ The network utilization increases slightly
+ The CPU utilization of the database server remains close to the normal average for a day

You need to resolve the performance issue?
What should you do?

You are developing a Windows Presentation Foundation (WPF) application. The application will run in a partially trusted sandbox. You plan to deploy the application on client computers by using the Click Once deployment technology. You plan to sign the deployment and application manifest by using a trusted publisher certificate. You need to ensure that the following requirements are met:
Users are not prompted for elevated permissions during application deployment The application can request elevated permissions at runtime Where should you install the trusted publisher certificate?
