A. Read
B. Read and Execute
C. Modify
D. Full Control

Answer C is correct. NTFS permissions are cumulative when a user is a member of more than one group with the exception of the Deny permission, which overrides all other permissions.

11. Allen has been granted Allow Full Control share permission on a network folder named Userfiles. NTFS permissions for the same folder are set to Allow Read and Execute for the HRusers group. Allen is a member of the HRusers group. What are Allen's effective permissions when he tries to access the Userfiles folder from the network?

A. Full Control
B. Read
C. Read and Execute
D. Deny Full Control

Answer C is correct. The most restrictive of NTFS and share permissions are applied when a shared folder is accessed from the network.

12. Gary wants to share a folder on his computer so that other users on the network can read and make modifications to his work. He wants some users to only read the files and others to read and modify them. When he tries to set permissions for the shared folder, he may not able to do that. What could be the reason?

A. Gary does not have sufficient rights to set share permissions.
B. Simple File Sharing is turned on.
C. Gary is not a member of the Administrators group.
D. Gary should set NTFS permissions first.

D. Send an email to all users saying that users printing unnecessary color copies will be billed.
E. Teach all users how to send color prints and how to send black prints.
Answer C is correct. You should first create two user groups, one that will print in color and the other that will print in black. Then, create two separate logical printers, one for color printing and the other for black printing. When this is done, you should configure permissions separately for each group.

16. The printer used in your office is heavily loaded and your manager has ordered two more similar printers. You have been tasked with the job of installing and configuring these new printers. Which of the following features can you use to share the printing load in your office?

A. Install new printers and configure availability hours for each printer.
B. Install new printers and configure printer pooling.
C. Install new printers and create three identical logical printers.
D. Make three equal groups of users and assign each group a separate printer.
Answer B is correct. When you have identical printers, you can share the printing load among several printers using the printer pooling feature in Windows XP Professional. All printers in the pool must be connected to the same port.

17. You have two identical printers in your office. Paper is jammed in one of the printers and you feel that you will have to call customer service to correct the printer problem. There are about 35 documents in the printer queue waiting to print. What can you do to temporarily resolve the problem so that users can continue to send documents for printing?

A. Redirect print jobs to the second printer.
B. Ask the users to cancel their documents and send them to the second printer.
C. Save the jobs in the spool folder of the print server.
D. Change the printer priority to its lowest value.

Answer A is correct. When you have two or more identical printers and one of them stops functioning, you can redirect the faulty printer's print jobs to another, identical printer. This action is transparent to the users and is performed from the print server.

18. You have three disks on a Windows XP Professional computer and you want to take advantage of Striped volumes. What is the first step you should take before you can configure a Striped volume?

A. Make sure that all disks have equal free space.
B. Convert all disks to Dynamic disks.
C. Format all disks with NTFS.
D. Make sure that all disks have equal unallocated space.

Answer B is correct. Dynamic disks only offer Simple, Spanned, and Striped volumes. Striped volumes are created by using unallocated space from two or more Dynamic disks. Striped volumes are not fault-tolerant and cannot be extended.

19. Most of the users on your network store documents on your computer, and you have configured file compression on the drive that is used by network users. Since users keep saving unnecessary documents that are not related to their jobs, your manager has asked you to use the disk quota feature to limit usage of disk space. Which of the following is true about disk quotas and file compression? Select three answers.

A. Disk quotas and file compression cannot be used together.
B. Disk quotas can only be configured on NTFS volumes.
C. Disk quotas can be enabled only for user groups.
D. Disk quotas can be enabled only for individual users.
E. Disk quotas take into account the size of the uncompressed files.

Answers B, D, and E are correct. Disk quotas work only on NTFS volumes, are configured on a per-user basis, and the uncompressed size of the files is taken into account when calculating space used by users.

20. Which of the following are features of the NTFS compression in Windows XP Professional? Select two answers.

A. Works on FAT volumes
B. Works on NTFS volumes
C. Works with file encryption
D. Individual files can be compressed
E. Works only on Dynamic disks

Answers B and D are correct. NTFS compression works only on NTFS volumes and can compress individual files. Folder compression, on the other hand, works on both FAT and NTFS volumes and can compress encrypted files but not individual files.

21. Your computer has a 120 GB hard disk divided into two partitions: drive C is 80 GB and NTFS and drive D is 40 GB and also NTFS. You compressed some files in the Documents folder on the C drive last month. Now, drive C is nearly full and you have moved the files from the Documents folder to the Docscopy folder on drive D, which is not compressed. What will be the compression state of the files after this action?

A. The files will get uncompressed.
B. The files will remain compressed.
C. The files will remain compressed but will uncompress when users open them.
D. There will be no change in the compression state.

Answer A is correct. When compressed files or folders are moved from one NTFS volume to another NTFS volume, they acquire the compression state of the destination folder. In this case, the destination folder that is not compressed is Docscopy.

22. Your computer is directly connected to the Internet, and you have been surfing the Web ever since you installed Windows XP Professional on it. It seems that there are a lot of temporary and junk files stored in the hard disk of your computer by various web sites. Which of the following utilities is the best to use to clear up the disk space?

A. Disk Defragmenter

24. Your manager received an email from one of your vendors that the newer versions of drivers for the sound cards installed on computers in your office are now available. You follow your manager's orders and download a new driver and install it on your computer first in order to test it. When you restart the computer, the sound card stops working. What are your options?

A. Write an email back to the vendor asking for help.
B. Use the Update Driver feature to install the driver directly from the vendor's web site.
C. Uninstall the sound card and install it again with the old driver.
D. Use the Roll Back Driver feature to uninstall the new driver and install the old driver.

Answer D is correct. The Roll Back Driver feature is used to uninstall a newly installed device driver and install the previously installed driver. Remember that this feature is not available for printer drivers.

25. It has come to your notice that some users in your office keep installing untested drivers for the purpose of improving sound quality on their desktops. You have responded to a few calls to address problems where users have installed such drivers. How can you prevent users from installing untested and unsigned device drivers on their computers in the future?

A. Define a written company policy so that no one is allowed to install any driver without your permission.
B. Configure driver signing options in each computer to block installation of unsigned drivers.
C. Configure driver signing options in each computer to warn before unsigned drivers are installed.
D. Write a script that will not allow any user to install any device driver on his computers.

Answer B is correct. The driver signing option can be set to block installation of unsigned device drivers on users' desktops. As an administrator, you can make this option the system default on every computer. Another way to prevent this is to take away the Load And Unload Device Drivers user rights from the users.

26. Your company is a marketing enterprise that has 10 telecommuters who carry their laptops with them for presentations. Some of these employees complain that their monitors turn off too quickly when they are doing presentations. How can you fix the problem?

A. Turn off the Hibernate mode on these notebooks.
B. Turn off the Standby mode on these notebooks.
C. Use the Presentation power scheme.
D. Use the Home/Office power scheme.

B. Open System Monitor and try to find out the reason for the problem.
C. Save the file, close it, and open it again.
D. Restart the computer.

Answer A is correct. You can use the Task Manager to end an application that is responding. When the application is not responding, you will not be able to save any work or close the file you are working on.

32. One of the Windows XP Professional computers in your small workgroup is configured as a print server. Users are complaining that it takes a long time to get their documents printed, and the print server seems to have become very slow in recent weeks. You now wish to gather performance data on this print server and analyze it whenever you get a chance later in the week. Which of the following options will help you accomplish your goal?

A. Open Task Manager to monitor the performance of the print server.
B. Use System Monitor to analyze the performance of the print server.
C. Use Performance console and use counter logs to collect performance data.
D. Use Performance Alerts to generate and send you a network message when the print server slows down.

Answer C is correct. The Performance Logs and Alerts snap-in is used to collect performance data for selected counters so that it can be analyzed at a later time. The Task Manager and System Monitor show real-time performance data.

33. You are now looking at the following performance log data collected in a text file during the past week.
Processor: %Processor Time-60%
Memory: Pages/sec-12
Physical Disk: %Disk Time-75%
Logical Disk: %Free Space-56%
Which of the following actions should remove the bottleneck in system performance?

A. Add a second CPU.
B. Add more RAM.
C. Replace the hard disk with a faster one.
D. Create one more logical partition.

Answer C is correct. A value of more than 50 percent of disk time for the physical disk object indicates that the hard disk is slower than expected and is the bottleneck. You should replace the currently installed hard disk with a faster hard disk.

34. You have enabled auditing for object access on file servers where you suspected that some unauthorized users were attempting to access confidential files. In which of the following Event Viewer logs should you look for auditing entries?

A. Application logs
B. Security logs
C. System logs
D. DNS logs

Answer B is correct. Auditing events are written to the security logs. Depending on the events for which you enabled auditing, you should look for entries in security logs to find out unauthorized logons.

35. You took over as the network administrator for a small company last week. While checking security and system logs for one of the file servers, you notice that no entries were written to the logfiles after you took over. What could be the reason?

A. The logs are configured to overwrite events as needed.
B. The logs are configured not to overwrite events.
C. The logs are configured to clear events on the last day of every week.
D. The logs are configured to overwrite events older than seven days.

Answer B is correct. When the event logs are configured not to overwrite events, the logfiles must be cleared manually. Otherwise, no new entries are written to the logfiles when the file reaches its configured size.

36. A new application installed on a database server in your office is dependent on a service that is installed with the application. The application and its associated service worked well for a week, and then started causing trouble. Users report that the application freezes repeatedly. You suspect that the cause of the problem is failure of the service. You want to get notified immediately if the service stops, so that you can diagnose the problem. How can you configure the service?

A. Configure the recovery option for the service to run a script that will send you an email.
B. Configure a performance alert for the service.
C. Use Task Manager to monitor the application and the service on the database server.
D. Ask a user to send you an email immediately after the application freezes.
Answer A is correct. The recovery options in the Properties dialog box of the service can be configured to run a program when the service fails. This program can be a script that will send you an email notifying you that the service has failed on the database server.

37. You want Jim to take care of backing up data on one of the file servers but do not want to grant him excessive permissions on the file server. Which of the following is your best option?

A. Make Jim a member of Administrators group.
B. Make Jim a member of Power Users group.
C. Make Jim a member of Backup Operators group.
D. Make Jim a member of Server Operators group.

Answer C is correct. To enable Jim to back up files and directories, you should make him a member of Backup Operators group. There is no need to make him a member of Administrators group because this will grant him more than the required permissions on the file server.

38. You took a full backup of the file server in your office last Friday night and then took incremental backups on Monday, Tuesday, and Wednesday nights. Today is Thursday and you have taken a differential backup just before installing a new, faster hard disk on the server. After the new hard disk is installed, you find that the server has crashed and you will have to restore the data from backups. Which of the following backup sets will restore the complete data on the file server using minimum tapes?

A. Full backup and Wednesday's incremental backup
B. Full backup and Thursday's differential backup
C. Full backup and incremental backups taken on Monday, Tuesday, and Wednesday
D. Just the differential backup taken on Thursday

Answer B is correct. The full backup taken on Friday night along with the differential backup taken on Thursday will restore complete up-to-date data on the file server. The differential backup contains all data that has changed after the last full backup.

39. After installing a new network adapter in one of your test computers, you find that the system boots but stops responding after you log on. Which of the following advanced boot options can help you resolve the problem? Select two answers.

A. Safe Mode
B. Safe Mode with Networking
C. Last Known Good Configuration
D. Recovery Console
E. Directory Services Restore Mode

Answers A and D are correct. You can boot the system in Safe Mode and remove the driver for the new network adapter. You can also use the Recovery Console to resolve the problem. Safe Mode with Networking will not work because the network adapter is causing the problem. The Last Known Good Configuration is useful only if you have not logged on to the system after making configuration changes.

40. You have not installed the Recovery Console on your Windows XP Professional computer. Is there a way to use the Recovery Console without installing it if the system develops a serious problem at a later date?

A. Yes, the Recovery Console is installed by default when the OS is installed.
B. No, you must install the Recovery Console before you can use it.
C. Yes, the Startup And Recovery options in System Properties actually include the Recovery Console.
D. Yes, the Recovery Console can be started from the Windows XP Professional setup CD-ROM.

Answer D is correct. You can start the Recovery Console from the Windows XP Professional setup CD-ROM by selecting the Repair option at the Welcome screen. You need not install the Recovery Console in order to use it.

41. You increased the screen resolution of your desktop to maximum and shut down the system for the day. The next morning the system did not boot at all. How can you resolve the problem?
A. Reinstall Windows XP Professional.
B. Start the system in VGA mode and change the resolution.
C. Use Recovery Console to remove the display adapter driver.
D. Do nothing. Restart the system two to three times and the problem will be fixed automatically.

Answer B is correct. The VGA mode starts the system in a very basic graphics mode, and you can change the screen resolution to the previous working one. Usually, the system will not allow you to change the resolution to one that is not supported by the display adapter.

42. You are in charge of networking in a very small office that has only 12 Windows XP Professional computers. Only one of the computers is connected to the network, and your manager wants you to configure all computers in such a way that everyone can share the Internet connection. Which of the following IP address ranges will be used in the network once you have configured the Internet Connection Sharing (ICS) on the computer connected to the Internet?

A. 192.168.0.1 to 192.168.0.255
B. 169.254.0.1 to 169.254.255.255
C. 172.16.0.1 to 172.31.255.255
D. 10.0.0.1 to 10.255.255.255

Answer A is correct. When ICS is enabled in a workgroup environment, the computer hosting the ICS service runs as a DHCP server also and allocates IP addresses in the range 192.168.0.1 to 192.168.0.255. It assigns the first address 192.168.0.1 for itself. The address range given in Answer B is used in the automatic private IP addressing (APIPA).

43. You are setting up a small network for a branch office of your company. The office will have a proxy server that will serve as a gateway to the Internet for all other computers in the network. You want to use an IP address range that will not conflict with the IP addresses on the Internet. The number of computers in the branch office will never be more than 100. Which of the following IP address ranges should you use for this office?

A. 192.168.0.1 to 192.168.0.255
B. 169.254.0.1 to 169.254.255.255
C. 172.16.0.1 to 172.31.255.255
D. 10.0.0.1 to 10.255.255.255

Answer A is correct. Since the number of computers in the branch office will never be more than 100, you can easily use the private IP addresses in class C address range. Although you can use the IP addresses given in answers C and D, it is wise to use the smallest range of addresses whenever possible.

44. You have been asked to analyze a slow connection from your office to one of the branch offices located in another city. Which of the following commands will let you analyze where the data packets that are traveling to and from your computers are being lost on the network path?

A. Ping
B. Pathping
C. Ipconfig
D. Tracert

Answer B is correct. Pathping is a TCP/IP troubleshooting utility that helps in finding out the loss of packets on the network path from one location to another. Ping is used to check connectivity, while Tracert is used to trace the route taken by the data packets from one network to another.

45. Even after you configured strong Password Policies in your network and set the appropriate NTFS permissions on company files, you notice that users keep guessing other accounts and passwords to access files that they are not supposed to. What else could you configure in Local Security Policy to prevent users from guessing passwords of authorized users? Select three answers.

A. Enable the Password Complexity Requirements Policy.
B. Ask authorized users to use strong passwords.
C. Set the Account Lockout Policies.
D. Enable auditing for logon events.
E. Disable network access for the file server from the network.

Answers B, C, and D are correct. In order to protect confidential files from unauthorized access and stop unauthorized users from attempting to guess passwords of authorized users, you should enable the auditing of logon events to the file server, ask authorized users to use strong passwords, and set the Account Lockout Policies.
