You are a developer for a XYZ Inc that provides free software over the Internet. You are developing en e-mail application that users all over the world can download. The application displays text strings in the user interface. At run time, these text strings must appear in the language that is appropriate to the locale setting of the computer running the application. You have resources to develop versions of the application for only four different cultures.You must ensure that your application will also be usable by people of other cultures.
How should you prepare the application for deployment?

A

Package a different assembly for each culture.

B

Package a different executable file for each culture.

C

Package a main assembly for source code and the default culture. Package satellite assemblies for the other cultures.

D

Package a main assembly for source code. Package satellite assemblies for each culture.

You are the administrator of a SQL Server 2000 computer. The server contains a database named FinanceData that is used by a client/server application. Each employee has a SQL Server login that the application uses to access the server.Your company hires a new employee named Andrew. You create a SQL Server login named Andrew. You also create a database user named Andrew in the database and grant the database user full permissions in the database.Whenever Andrew runs the client/server application, he receives the following error message: "Invalid object name." Andrew also reports that he cannot access the database by using the application.You need to ensure that Andrew can use the application. Which Transact-SQL statement should you execute?

A

EXEC sp_defaultdb 'Andrew','FinanceData'

B

GRANT ALL ON FinanceData TO Andrew

C

EXEC sp_addlogin 'Andrew'

D

EXEC sp_grantdbaccess 'FinanceData','Andrew'GOsp_addrolemember 'db_datareader','Andrew'

You install and run a third-party 32-bit application named Application on your Windows 2000 Server computer. After several days, the application stops responding. You open Task Manager and find that the CPU usage is at 100 percent. The normal range of CPU usage on the server is from 20 percent to 30 percent You end the application. However, you see that the CPU on the server is still at 100 percent. Task Manager shows no other applications running. You then examine the Processes page in Task Manager and confirm that the Application.exe process is no longer running. You want to return the CPU usage to its normal range. What should you do?

A

Use Computer Management to stop and restart the Server service

B

Use Computer Management to stop and restart the Workstation service

C

Use Task Manager to end any related child processes

D

Use Task Manager to end and automatically restart the Explorer.exe process

E

None of above

You install a new multiple-process database application named Application on your Windows 2000 Server computer.

A

End the task named Application

B

End the Application.exe process

C

End the Application.exe process tree

D

End both the Explorer.exe process and the Application.exe process

E

None of above
