  • 第2题：

    You are the administrator of a Windows 2000 Professional computer named Computer1. Computer1 has a shared color laser printer named Printer1. Printer1 will not turn on.

    The printer queue for Printer1 has three jobs waiting to print. You want to enable the three waiting print jobs to print to an identical print device, which has been shared as Printer2 on Computer2. You also want to connect users who currently connect to Printer1 to automatically use Printer2 without having to reconfigure their default printer.

    What should you do?

    A．Enable bidirectional support for Printer1.

    B．Change the share name of Printer2 to Printer1.

    C．Configure Printer1 to add a port, and set the port to \\Computer2\Printer2.

    D．Configure the printer server properties to use the path \\Computer2\$Winnt$\System32\Spool\Printers.


    正确答案：C
    解析：Explanation: The twoprint devices will use the same printer driver because they are identical. This makes it possible to redirect the print jobs. To redirect all print jobs from printer1 to printer2 you must add the port \\computer2\printer2 to printer1.

    Incorrect Answers:
    A: Disabling the bidirectional support option will prevent the print device from communicating with the printer. This will prevent you from redirecting the print jobs.

    B: Changing the share name of printer2 to printer1 will not redirect any printer jobs as you would still have two distinct printers name \\computer1\printer1 and \\computer2\printer1. Instead you should add the port \\computer2\printer2 to printer1 so it would redirect all print jobs from printer1 to printer2.

    D: The actual path to the spool folder is not used for redirecting print jobs. It is used to save pending print jobs. To redirect all print jobs from printer1 to printer2 you must add the port \\computer2\printer2 to printer1.

  • 第6题：

    We plan to build a skyscraper here.

    A:frame
    B:raise
    C:compose
    D:erect

    答案：D
    解析：
    本题考查的是对动词的认知。这句话的意思是：我们计划在这里建设一座摩天大楼。build的意思是建立。选项A frame给……加框，例如：Will you frame the picture？你给这个画加个框好吗？选项B raise提起，举起，竖起，例如：When he saw the principal, he raised his hand in salutation．他看到校长时举手敬礼。选项C compose组成，构成，例如：These twelve men are believed to compose the jury．据说陪审团是由这12人组成的。选项D erect建立，树立，例如：I don't want to see a system like that will be erected．我不希望看到那种制度将被建立起来。build和erect意思最接近，所以选D。
