You create a Windows application by using the .NET Framework 3.5.
The application uses a Microsoft SQL Server 2008 database.
You discover that the application is non-responsive and performs slowly at certain times during the day.
Twenty-five additional users are added to the application to meet a deadline.
You need to ensure that all users experience a consistent level of high application performance
throughout the day. You want to achieve this goal by using minimum development effort.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You create a Windows application by using the .NET Framework 3.5.
The application is used for stock trading purposes. The application has the following features:
The application is deployed to workstations that contain four monitors.
Only one instance of the application can be run at a time.
The application has a multiple-document interface (MDI).
A third-party control is used on the Windows form to display real-time data by using graphs.
The stack of monitors on each workstation is two monitors high and two monitors wide.
When multiple stock quotes are viewed at the same time, the Windows form has to be extended to
another monitor.
The information has to be viewed across the monitors together.
You need to modify the application to meet the following requirements:
Users can compare two or more stock quotes at the same time.
The Windows form can be maximized and restored to the monitor selected by the user.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You maintain a Windows Forms application and an ASP.NET application.
The Windows Forms application has the following features:
The application impersonates the logged-on user.
The data is stored in a Microsoft SQL Server 2008 database.
The application grants user access to data by calling the IPrincipal.IsInRole method on the basis of user
roles.
The ASP.NET application uses forms-based authentication to authenticate users.
You need to share the login and user role information between the Windows Forms application and the
ASP.NET application.
What should you do?

You are creating a Windows application by using the .NET Framework 3.5.
Your application requires a local data store that requires no administrative privileges to install. The data
store must use the ClickOnce deployment.
The application will cache data when offline. When the application returns online, it must synchronize data
with a corporate SQL Server 2008 database.
You need to identify a local data store that meets the outlined requirements. You also need to ensure that
the application uses minimum possible memory.
Which data store should you use?

You are creating a Windows application by using the .NET Framework 3.5.
The application will be deployed by using the ClickOnce deployment. The application must support offline
use. The application must also have minimum dependency on external components.
You need to choose the most secure data storage tool for your application.
