You are creating a Windows application by using the .NET Framework 3.5.
The application has the following features:
Users access the application from their local computers.
Each user specifies the data file to be used for the current session at the start of the application.
You plan to design a strategy to enable users to share their data files with other users.
You need to implement the strategy to meet the following requirements:
Users can open the data file only by using a password.
Users can work on the data file only by using the application.
What should you do?

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.
You plan to test the application by using 5,000 records in a limited test environment.
The application will process 1 million records in a production environment.
You need to test the application to identify potential problems that might occur when the application is
moved to the production environment.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You have developed a console application by using the Microsoft .NET Framework 1.1. The console
application uses a set of assemblies for the business logic and the data layer.
You plan to convert the console application to a Windows Forms application.
You need to design a conversion strategy by using minimum amount of time and development effort.
What should you do?

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 create a Windows application by using the .NET Framework 3.5.
You create a Windows user control in the application.
The application contains the following code segment. (Line numbers are included for reference only.)
01 public struct FullName
02 {
03 public string FirstName { get; set; }
04 public string LastName { get; set; }
05 }
The user control has a property named UserName of the FullName type. You add the user control to a
Windows form.
During the design phase, the UserName property must be allowed to update the FirstName and
LastName properties as comma-delimited values in the property window.
You need to ensure that the properties in the FullName structure are represented as string values.
What should you do?

You are creating a Windows application by using the .NET Framework 3.5.
The application has the following specifications:
It uses a centralized Microsoft SQL Server 2008 database instance.
It is deployed to several computers within the network.
It retrieves and updates the records of the Customer table.
A customer record can exist on multiple forms within the application. Users log on to the application by
using their unique user ID. You implement optimistic concurrency on the Customer table.
You need to design a strategy to detect conflicts by using minimum amount of network bandwidth.
What should you do?

You are creating a Windows application that processes sales orders by using the .NET Framework 3.5.
The application has the following specifications:
It connects to a Microsoft SQL Server 2008 database.
It retrieves data from a table named Products.
The product table has three columns named Name, Description, and Quantity. The application uses the
Name and Description columns as lookup fields. It updates the Quantity column when orders are placed.
You need to design a concurrency management strategy that meets the following requirements:
Data integrity is maintained during the update process.
Database locking for the lookup data is minimal.
What should you do?

You are creating a Windows application by using the .NET Framework 3.5.
The application has the following features:
Users access the application from their local computers.
Each user specifies the data file to be used for the current session at the start of the application.
You plan to design a strategy to enable users to share their data files with other users.
You need to implement the strategy to meet the following requirements:
Users can open the data file only by using a password.
Users can work on the data file only by using the application.
What should you do?

You create a Windows application by using the .NET Framework 3.5.
You plan to use ClickOnce deployment.
The application will run in a partial trust environment.
You need to store user preferences for the application.
