One final performance tidbit has to do with display effects. Strangely, Microsoft placed these settings in the System control panel instead of the Display control panel; click the Advanced tab, the Settings button in the Performance box, and have a look at the nine zillion options on the Visual Effects tab (shown in Figure 14-9). If you want maximum performance and don't have a lot of time to tweak individual effects, just click the Adjust For Best Performance radio button.
Figure 14-9: The fewer visual effects, the faster your PC goes.
1. You install Windows XP Professional onto 14 computers using a disk cloning technique. You discover that (unbeknownst to you) the 14 machines have dual Pentium processors. However, the machine you used to make the master disk image only has one CPU. As a result, the cloned systems are not using their second CPUs. You do not want to reclone the operating system onto the 14 computers if you can help it. What can you do? (Choose the best answer.)
A. Go to each machine's System control panel. Click the Advanced tab and check the box labeled 'Enable SMP.'
B. Go to each machine's System control panel. Click the Hardware tab and check the box labeled 'Enable SMP.'
C. Go to each machine's System control panel. Click the Hardware tab, open Device Manager, and update the driver for the Computer device to a multiprocessor version.
D. Go to each machine and enable multiprocessor support in the BIOS.
E. Go to each machine and remove the second CPU.
2. What is the default size of the pagefile? (Choose one answer.)
A. 1.0 times installed RAM
B. 1.5 times installed RAM
C. 2.0 times installed RAM
D. 256MB minus installed RAM
3. On a multiprocessor machine, Windows XP's Performance console lets you use System Monitor to track activity on each CPU separately. In this situation, the graph for each CPU's 'percent processor time' would correspond to a separate:
4. You set up a Windows XP Professional computer in a small workgroup. You decide to dedicate this particular computer to sharing files for the group, and you put all the shared files onto this machine. You're aware that no more than 10 computers can access these files simultaneously, but that's not a problem because your workgroup consists of 8 computers. You install the File and Printer Sharing service and bind it to the local area connection.
Before you lock away the monitor in a closet, what performance setting or settings should you change from the default value? (Choose all that apply.)
A. Optimize Performance For Background Services, in the Processor Scheduling area of the System control panel
B. System Cache, in the Memory Usage area of the System control panel
C. Optimize Performance For Applications, in the System control panel
D. Optimize Performance For Workgroup Services, in the System control panel
E. Increase the priority of the LSASS.EXE process, in Task Manager
5. While logged on as an Administrator, you set up Scheduled Tasks to run the Backup program every night at 2 a.m. to perform a data folder backup from your C drive to your D drive. For the task's security context, you specify a member of the Users group. The next day, you find that Backup did not execute. Why not?
A. You must create the task when logged on as a Backup Operator.
B. You must specify a different security context.
C. You must use the AT.EXE command to run Backup.
D. NTBACKUP doesn't perform disk-to-disk backups.
6. You run System Monitor on a PC whose user is complaining of poor performance. You add counters for Available MBytes and Pages/second for the Memory object. After watching these values while the user performs normal daily tasks, you see that Available MBytes frequently drops below 16 but never drops below 8. The Pages/second graph shows frequent spikes in the range from 5 to 10. What do these monitoring statistics indicate? (Choose the best answer.)
A. The user's pagefile is heavily fragmented.
B. The user's disk is heavily fragmented.
C. The user needs more RAM.
D. The user has enough RAM.
E. The foreground/background setting needs adjusting.
F. The maximum pagefile size is set too low.
7. Bob comes to you with a problem. He has 920MB used on a 1000MB hard drive that is formatted with NTFS. When he runs DFRG.MSC, he receives a warning message. Bob knows he has too many files on his system. Of the following values, which is the smallest amount of additional space that Bob can free up in order to make the error message go away? (Choose the best answer.)
8. In the Task Manager's Performance tab, what's the commit charge limit?
A. The current pagefile size
B. The minimum pagefile size
C. The maximum pagefile size
D. The maximum pagefile size plus installed RAM
E. The maximum pagefile size minus installed RAM
1. C. By 'updating' the driver for the computer itself, you're actually changing the Hardware Abstraction Layer (HAL), which you must do if the multiprocessor machines are to recognize the second processor. Review 'Adding a second processor.'
