Questions (August 16, 2002)

Question 1
You have a Windows XP Professional laptop that you use for all your work for the New Zealand Space Agency (NZSA). When you're at your Auckland office, you connect the laptop to a docking station, which lets you access the NZSA network through a built in NIC. The docking station also has a built in DVD-ROM drive.

When you're at the Tonga Launch Facility, you dial in to a Windows 2000 RRAS server to access the NZSA network. You want to disable the docking station NIC and the DVD-ROM drive when you're at home and on site at the Tonga Launch Facility. What sort of profile should you create for your laptop to prevent Windows XP from attempting to start the NIC and DVD-ROM drive when you're out of office? (Choose the best answer.)

  1. Personal roaming profile
  2. Low profile
  3. Hardware profile
  4. Local profile
  5. Mandatory roaming profile

Question 2
You're interested in monitoring the performance on your Windows XP Professional workstation because you've been running several resource-intensive applications and they haven't been responding as quickly as you'd hoped. Your hard disk seems to run continuously, and some applications take a long time to load. Your machine has a Pentium 4 1.4Ghz processor, 128MB of RAM, and an EIDE hard disk. You run Performance Monitor note the average values for the following statistics:

  • Physical Disk, Current Disk Queue Length: 2
  • Memory, Pages/Sec: 25
  • Logical Disk, % Free Space: 25
  • Processor, % Processor Time: 34

What should you do to improve system performance? (Choose the best answer.)

  1. Add a second CPU to the system
  2. Increase the CPU priority for all applications
  3. Increase the amount of RAM in the system
  4. Run Disk Cleanup
  5. Upgrade the hard drive to a SCSI hard drive

Question 3
You've configured roaming profiles for several users at your company. Some of these users save large multimedia documents to their My Documents folders on their Windows XP Professional workstations. The My Documents folder is part of a user's profile, and these users tend to experience slow logon times because of the time it takes to download their profiles to the workstations from the server. You want to store the contents of the My Documents folders on a central server instead of having users download them to their desktops whenever they log on. What's the best way to accomplish this? (Choose the best answer.)

  1. Use Group Policy to enable Folder Redirection and configure the My Documents folder to redirect to a share on the centralized server.
  2. Change the name of the ntuser.dat file to ntuser.man to change the roaming profile from a personal roaming profile to a mandatory roaming profile.
  3. Set a disk quota on the My Documents folder on each user's desktop. Set a maximum limit on the amount of data that a user can save to that folder and check the "Redirect excess data to network server" box. Enter a UNC path with the location of the network share you want the data to redirect to.
  4. Configure the Desktop folder to be available offline through the Offline Files. Configure the folder to synchronize when a users logs on or logs off.
  5. Create an empty folder on the network server. Share this folder and configure it as a Dfs root share. Configure the My Documents folder for each user to be a Dfs link.

Answer to Question 1
The correct answer is C—Hardware profile. Hardware profiles tell Windows XP which devices to start when a system boots and which settings to use for each device. When you install Windows XP, the system automatically creates a default hardware profile. By default, this hardware profile enables every device that's installed on the computer.

Hardware profiles let you configure different settings for when you're connected to or away from the network. You can change the devices that your computer uses when you move from location to location. One hardware profile might enable components such as a NIC and a DVD-ROM drive, and another profile might disable those devices so that you don't receive errors when starting the system away from a docking station.

Answer to Question 2
The correct answer is C—Increase the amount of RAM in the system. The Memory counter shows the most dire result, with 25 pages swapping out of memory to the hard disk every second. You want this number to be under 15. The other results are all acceptable. If you work with Windows XP, knowing the acceptable performance values is important. When you increase the amount of RAM, the system can store more pages in memory. With more pages in memory, the system won't have to swap pages to the hard disk as frequently.

Answer to Question 3
The correct answer is A—Use Group Policy to enable Folder Redirection and configure the My Documents folder to redirect to a share on the centralized server. You use Group Policy's Folder Redirection extension to redirect certain Windows 2000 special folders to network locations. Special folders are folders such as My Documents and My Pictures, which are located under Documents and Settings. With roaming user profiles, only the network path to the My Documents folder is part of the roaming user profile, not the My Documents folder itself. Therefore, its contents do not have to be copied back and forth between the client computer and the server each time the user logs on or off, and the process of logging on or off can be much faster than it was in Windows NT 4.0.
