You are creating a Windows application by using the .NET Framework 3.5. The application uses Microsoft SQL Server 2008 authentication to connect to a relational database. You need to devise a storage strategy for the connection string to prevent unauthorized users from accessing the information. What should you do?

5:You create a Windows application by using the .NET Framework 3.5. You plan to deploy an application by using the ClickOnce deployment method. The application has the following specifications:

* It contains multiple components.
* It is based on the .NET Framework 3.5.
* The .NET Framework 3.5 is not installed on all the client computers.

You need to install the .NET Framework 3.5 on the client computers during the application deployment process. What should you do?

You are creating a Windows application by using the .NET Framework 3.5. The application connects to a database within the corporate network. It retrieves data from a read-only database. The database contains a table named Customers. An XML file that contains new customer data is periodically provided to the application. The XML file has the following specifications:

* It has the same schema as that of the Customers table.
* It will be integrated into the Customers table.
* It will be removed after data integration.

The application requires data from the Customers table and the XML file to bind to a DataGridView control.

You need to ensure that data can be retrieved together from the two data sources by using minimum development effort. What should you do?

You are creating a Windows application by using the .NET Framework 3.5.The application makes function calls to an unmanaged library to control the operation of a robot. You create a class that consumes significant memory during function calls to the unmanaged library. You discover that memory consumption increases over time. You need to ensure that the application consistentlyconsumes minimum memory. What should you do?

You create a Windows application by using the .NET Framework 3.5. The application is used by employees to submit timesheets and to generate reports. The application must contain a Managers role and an Employees role. You have the following security requirements:

* Members of the Managers role can approve the timesheets.
* Members of the Employees role can generate reports only if they are a member of the local administrators group.
* Members of the Managers role can access the application from untrusted domains.

You need to design a security model to meet the design requirements. What should you do ?

You are creating a Windows application by using the .NET Framework 3.5. The application stores customer details in a database within the corporate network. The application has a form that contains a TextBox control to capture the customer name. The auto-complete feature must be used in the TextBox control to display the
customer names entered since the application started.You need to ensure that the application meets the following requirements:

* It is available in the offline mode.
* It provides the fastest response time for the auto-complete feature.

What should you do?

4:You are creating a Windows application by using the .NET Framework 3.5. The application must meet the following requirements:

* It records the details of the users who modify sensitive information.
* It requires a context-related stack dump for the details.
* It is executed by using the local user account without administrative privileges.

You need to ensure that the requirements are met by using minimum possible development effort. What should you do?

8:You are creating a Windows application by using the .NET Framework 3.5. The application will be used to retrieve information about the technical skills of the employees. The data will be retrieved from the following related tables on a Microsoft SQL Server 2008 database instance by using LINQ to SQL:

* EmployeeSkills table
* TechnicalSkills table

The application must retrieve data from the TechnicalSkills table only when the correspondingEmployeeSkills rating value is 3. In addition, the application must
minimize data returned and prevent duplicate information from being returned.

You need to meet the outlined requirements in one roundtrip to the database.What should you do?

You create a Windows Forms application by using the .NET Framework 3.5. The application is used for audio/video management. The application provides the following features:

* Usage license for music or video can be purchased from an online store.
* Backup of music and video for disaster recovery can be done.
* Custom playlists can be created to organize downloaded content.

The application has the following requirements:
* A license file is required to play local music or video.
* Users can access previously-purchased content from any computer that runs the application.
* User theme settings for the UI might only be customized for each computer.

You need to design a state and data management strategy that meets the requirements.What should you do?
