You have installed two shared printers for a print device on a Windows 2000 Server. Both printers are available to all users. They are shared as Admin and Executive. Admin is configured with a priority of 90, Executive is configured with a priority of 50. Now, you are advised to prevent the printer Executive to be visible to all users. Only members of the Executive group should be able to print to Executive. What should you do? Deny print permission to the Everyone Group Change the priority of Executive to 99 Install a second printer driver for the print device. Set NTFS permissions to the new driver files so that only the Executive Group is allowed to access the files. Allow the Executive Group print permission only. Remove the sharename Executive and add the sharename Executive$. Reconnect all members of the Executive Group to the new sharename. You have a local Win 2000 network setup as a Workgroup. There are several Win 2000 remote sites also setup as a Workgroup. The remote sites connect to local resources by direct dial modems. Member1 is a server on the local network, it has two adapters, adapter1 is an NIC to the local network and Adapter2 is an NIC connected to a DSL modem which is connected to the Internet. You install ICS on Member1 to allow local network to have Internet access. After install, remote sites are unable to view local resources and local users are still not able to connect to the Internet. Choose one to correct problem: Install NAT Install ICS on Adapter1 Install Proxy Server on local network Install ICS on Adapter2 You must back up the Registry, the COM+ Class Registration database, the system boot files, the Certificate Server database, the Active Directory Services database, and the SYSVOL directory on a Windows 2000 Active Directory domain controller. The domain controller is a Pentium 200 MHz with a RAID 5 array composed of ten 3-GB partitions. How can you back up the appropriate files while minimizing the time the backup takes? Use Windows Backup to create a backup of specified folders Use Windows Backup to create a differential backup Use Windows Backup to perform a full system backup Use Windows Backup to back up the System State Data Due to strict security limitations of your Windows 2000 production environment, you must prevent any unsigned drivers from being installed on any computer in your Windows 2000 network. The network consists of Windows 2000 domain controllers, Windows 2000 file and print servers, and Windows 2000 Professional computers. How can you prevent the installation of any unsigned drivers on all the computers on your network? Configure the domain controllers, file and print servers, and client computers to Ignore unsigned drivers Configure the domain controllers, file and print servers, and client computers to Block unsigned drivers Implement a Group Policy to Ignore signature verification Configure a Local Policy on the main Windows 2000 domain controller You are the administrator for a Windows 2000 network. The network consists of Windows 2000 Server computers and Windows 2000 Professional client computers. The network is configured to use Active Directory and auditing.You perform regular maintenance on the network. You like to periodically use the Event Viewer to check the success or failure of events that have auditing enabled.What do you use to monitor these events? DNS Server Application log System log Security log You are installing a new network adapter for a Windows 2000 Server computer on the Windows 2000 network you administer.

Event Logs Driver Signing Service Pack Slipstreaming Device Manager You install a Windows 2000 Server computer on your network. You place several shared folders on a 12-GB primary partition formatted as FAT32. During nine months of continuous operation, the number of users who access the server and their access frequency remains constant. The average size of the files on the server remains approximately constant. After the server runs continuously for nine months, users report that the server does not retrieve files from the shared folders as fast as when you first installed the server. What should you do to resolve the problem? Convert the disk that contains the shared folders to a dynamic disk. Convert the partition that contains the shared folders to NTFS. Defragment the disk that contains the shared folders. Move the paging file to the partition that contains the shared folders. Drive C: on your Windows 2000 server has a compressed folder on it named C:\Server_Files. You must move this folder to Drive D: and encrypt this folder. Drive D: is a 5-GB FAT32 volume and Drive C: is a 3-GB NTFS partition. How can you move the file to the D: volume and encrypt it? You convert drive D: to an NTFS partition, move the C:\Server_Files folder to the D: drive, right-click on the folder's Properties, select Advanced from the General Tab, and select the check box to "Encrypt contents to secure data". You move the C:\Server_Files folder to the D: drive, right-click on the folder's Properties, select Advanced from the General Tab, and select the check box to "Encrypt contents to secure data". You convert drive D: to an NTFS partition, move the C:\Server_Files folder to the D: drive, right-click on the folder's Properties, select Advanced from the General Tab, remove the compression setting from the folder, and select the check box to "Encrypt contents to secure data". You move the C:\Server_Files folder to the D: drive, right-click on the folder's Properties, select Advanced from the General Tab, remove the compression settings from the folder, and select the check box to "Encrypt contents to secure data". You are the administrator of a Windows 2000 Server computer. A folder named HR-Data on the system partition of the server is shared on the network as HR-Data. The owner of the HR-Data folder is Administrators. The shared permissions and NTFS permissions are shown in the following table. Katrin creates a file in the HR-Data folder. She sets the NTFS permissions for the file to list only herself on the access control list, with Full Control permission. Katrin then leaves on vacation and cannot be contacted. Later, you discover that the file contains sensitive information and must be removed from the server as soon as possible. You want to delete the file without modifying any of the permissions for other files in the HR-Data folder. You want your actions to have least possible impact on users who may be using other files in the HR-Data folder. You want to use the minimum amount of authority necessary to delete the file. What should you do? Grant yourself Full Control permission for only the HR-data folder and not its subobjects. Delete the file. Then remove Full Control permission for HR-Data folder. Take ownership of the HR-Data folder. When prompted, take ownership of the existing files. Grant yourself Full Control permission for the file. Delete the file. Take ownership of the file. Grant yourself Modify permission for the file. Delete the file. Grant yourself Modify permission for the HR-Data folder and its subobjects. Delete the file.
