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?
A.
Create a Microsoft SQL Server 2008 database for each user on the client computer. Use the database
as a data file.
Set a password for the system administrator login.
Allow users to share the password with other users through an e-mail message.
B.
Create an XML file to be used as a data file for each user, and then place the files in a shared folder on
the corporate network.
Protect the shared folder by using a password.
Allow users to share the password with other users through an e-mail message.
C.
Create a Microsoft Office Excel 2007 workbook to be used as a data file.
Associate the .xslx extension of the workbook with the application.
Protect the Office Excel 2007 workbook by using a password.
Allow users to share the workbook with other users through an e-mail message.
D.
Create a Microsoft SQL Server 3.5 Compact database file along with a custom file extension to be
used as a data file.
Associate the custom file extension with the application.
Encrypt the data file with a password.
Allow users to share their data file with other users through an e-mail message.
