第3题：

You are the administrator of a Windows 2000 Professional computer that has a shared printer. Several departments in your company use the shared printer.

The Sales department frequently prints multiple-page presentation graphics, which take a long time to print. Users in other departments who have short messages to print must wait an unnecessarily long time for their jobs to print.

You want to improve the efficiency of printing for all users who use the shared printer. You want to accomplish this with the least amount of administrative effort.

What should you do?

A．Configure the priority of the printer to 50. Add a new printer, and set the priority to 1. For the new printer, deny print permission for users in the Sales department.

B．Configure the priority of the printer to 50. Add a new printer, and set the priority to 99. For the new printer, deny print permissions for users in the Sales department.

C．Monitor the print queue and raise the priority of all print jobs that are sent by users who are not members of the Sales department.

D．Delete the old printer. Add a new printer, and set the priority to a higher value. Pause the print queue only when graphic intensive print jobs are printing.


正确答案：B
解析：Explanation: The Sales department has long-running printing jobs that are blocking the print device for long periods of time. In order to give the other departments' print jobs higher priority than the Sales department's print jobs, we create a new printer with higher priority. We deny print permission for the Sales department on the new printer.

Note: The highest printer priority is 99 and the lowest is 1.
We should also set the new printer as the default printer for all users except for users belonging to the Sales department.

Incorrect Answers:
A: Specifying a priority of 1 for the new printer will give the new printer a lower priority than the existing printer will. The long-running print jobs from the Sales department would have higher priority than the other departments.

C: Monitoring the print queue and raising the priority of all print jobs that are sent by users who are not members of the Sales department would require a lot of administrative effort.

D: This proposed solution only uses one printer and requires the administrator to manually pause print jobs to give certain print jobs higher priority. This would require an enormous amount of administrative effort and is therefore not the best solution.
