第1题：

有如下程序： Private Sub Form Click() Dim Check，Counter Check=True Counter=0 Do Do While Counter＜20 Counter=Counter+1 If Counter=10 Then Check=False Exit Do End If Loop Loop Until Check=False Print Counter，Check End Sub 程序运行后，单击窗体，输出结果为

A．15 0

B．20 -1

C．10 Tree

D．10 False


正确答案：D
解析：本题考查嵌套的Do…Loop循环。Do循环嵌套的规则与For-Next循环相同，按照先进后出、后进先出的原则，不能交叉。考生需判断程序在何时跳出循环，内层循环是在Counter20时，对其加1，但要注意循环内的条件语句，当Counter=10时，跳出内层循环，同时将Check设为False。外层循环的循环条件是Check=False，所以当程序跳出内层循环时，外层循环的条件也满足了，故同时也跳出循环，此时Counter=10，Check为False，选项D正确。

第7题：

You are the administrator of the homeoffice.local domain. You want to create a shared printer for the company's executives so that they do not have to wait for their documents to print when the default printer's queue contains a large number of documents.

You configure the new high-priority printer and want to set permissions for the groups shown in the exhibit. Note: The default settings have been cleared.

You select the check box to allow Print permission for the Executives group. You want only the Administrators, Print Operators, Server Operators, and Executives group to be able to print to the printer. What can you do? (Select all that apply).

A．Remove the Everyone group.

B．Select the check box to deny Print permission for the Everyone group.

C．Select the check box to deny Manage Documents permission for Everyone group.

D．Select all Deny check boxes for the Everyone group.

E．Clear all check boxes for Everyone group.


正确答案：AE
解析：Explanation: By default the Everyone group, to which all users are automatically added, has access to printer. Therefore, by removing the Everyone group, only the groups that have been explicitly been given permission to the printer would be able to use the printer. The same could be achieved by removing all permissions from the Everyone group.
Incorrect answers:
B: When a user has conflicting permissions to network resources as a result to his or her membership to one or more groups, the most restrictive permission is applied. However, a deny permission overrides all other permissions. All users are automatically added to the Everyone group therefore the deny print permission applied to the Everyone group will be inherited by all users and would override their other permissions to the printer. All users would then not be able to print.

C: When a user has conflicting permissions to network resources as a result to his or her membership to one or more groups, the most restrictive permission is applied. However, a deny permission overrides all other permissions. All users are automatically added to the Everyone group therefore the deny manage documents permission applied to the Everyone group will be inherited by all users and would override their other manage documents permissions to the printer. This will however not prevent all users from be able to use the printer.

D: When a user has conflicting permissions to network resources as a result to his or her membership to one or more groups, the most restrictive permission is applied. However, a deny permission overrides all other permissions. All users are automatically added to the Everyone group therefore the deny permissions are applied to the Everyone group will be inherited by all users and would override their other permissions to the printer. All users would then not have access to the printer.
