单选题You are the desktop administrator of your company’s network. You install a print device on a Windows XP Professional computer. This print device should be used only by the desktop administration staff and by managers. You share the printer on the network as DTA-Print and assign Allow - Print permissions to the DTA-S group, which includes staff members’ accounts, and the DTA-M group, which includes managers’ accounts. Later, the managers report that they must wait a long time for their jobs to print. You discover that the desktop administration staff generates many problematic print jobs. As a result, the managers’ print jobs must wait a long time in the print queue. You need to ensure that the managers’ print jobs print as quickly as possible while minimizing hardware costs. What should you do?()A
Install a second printer for the same print device on the Windows XP Professional computer. Share this printer as DTA-Manager, and grant Allow - Print permission to the DTA-M group only. Configure a priority setting of 1 on DTA-Print. Configure a priority setting of 99 on DTA-Manager.B
Install a second printer for the same print device on the Windows XP Professional computer. Share this printer as DTA-Manager, and grant Allow - Print permissions to the DTA-M group only. Configure a priority setting of 99 on DTA-Print. Configure a priority setting of 1 on DTA-Manager. C
Connect a second print device to the Windows XP Professional computer. Create a printer pool from the first defined printer. Configure a priority setting of 1 on the printer pool. Grant Allow - Manage Documents permission to DTA-M group.D
