  • [单选题]You are the administrator of your company's network. A user named Paul in the service department has a Windows 2000 Professional computer. Paul needs to access the files that are in a shared folder on his computer. A local group named Sales has permissions to access the data. Paul is a member of the Sales local group but he cannot access the file he needs.What should you do?
  • Remove Paul from any other group that has been explicitly denied access to the Sales folder.

  • 解析:解析:Explanation: The Sales group, which Paul is a member of, has permission to access the files. However, Paul still cannot access the files. It would seem that Paul has a permissions conflict. A user can be granted file permissions in a number of contexts: as a user or as a member of a user group. When a user has different file permissions in multiple contexts, the most restrictive permission is applied. Furthermore, the deny permission overrides all other permissions. As Paul does not have access to the file you must therefore assume Paul has explicitly been denied access to the file in some context, as member of one or more groups that have been denied access to the file. You would thus have to remove Paul from such a group so that the restriction is not applied to Paul.

  • [单选题]You are the administrator of a Windows NT Server 4.0 computer named Ezonexam1. Ezonexam1 is a backup domain controller (BDC), and a member of Ezonexam.com's Windows 2000 Active Directory domain. Ezonexam1 contains five hard disks. Disk 0 and 1 are configured as a Windows NT 4.0 mirror set.The mirror set contains the operating system files and 500 MB of free disk space. Disk 2, 3 and 4 are configured as a Windows NT 4.0 stripe set with parity and contain employee data files. The Windows NT 4.0 stripe set with parity has a maximum capacity of 140 GB and contains 15 GB of free disk space.
  • Upgrade Ezonexam1 to Windows 2000 Server. During the upgrade, select the option to make Ezonexam1 a domain controller. After the upgrade is complete, demote Ezonexam1.

  • 解析:解析:Explanation: We upgrade Ezonexam1. We have no choice that the upgraded Windows 2000 Server will be a domain controller. We are then able to use the dcpromo.exe utility to remove the Active Directory and demote the Domain controller to a member server.

  • [单选题]You are the administrator of a SQL Server 2000 computer. You create a Data Transformation Services (DTS) package. The package is stored as a local package on the server. The package exports data from an online transaction processing (OLTP) database system to an online analytical processing (OLAP) database system that is located on a second SQL Server 2000 computer.You want the package to execute automatically each evening at 8:00 P.M. What should you do?
  • Use SQL Server Enterprise Manager to create a new job Create a CmdExec job step that runs the dtsrun utility Schedule the job to run each night at 8:00 P.M.

  • 解析:解析:Explanation: Transfers can be defined and stored in a DTS package, which can then be run from a command line using the dtsrun utility (DTSRUN.EXE). CmdExec job steps are operating system commands or executable programs ending with .bat, .cmd, .com, or .exe. In this scenario we create a job consisting of a single cmdexec job step which runs the DTS package using the dtsrun utility.
