Objective 4.1 Monitor, Optimize, and Troubleshoot Performance of the Windows XP Professional Desktop
24-11
C. Incorrect: Optimizing processor scheduling for background services is useful on
servers because it ensures that interactive applications do not reduce the performance
of a server’s primary tasks. However, it does reduce system responsiveness
for users working interactively with the computer because background services
receive higher priority than interactive applications.
D. Incorrect: Optimizing memory usage for system cache improves the performance
of file sharing and Web services. However, when you allocate more of the
system RAM to these services, interactive applications suffer.
E. Incorrect: Windows XP uses virtual memory as an extension of the system’s
physical RAM. It is a slow process to page data from the physical memory to the
virtual memory located on the system’s hard disk, but decreasing the size of the
paging file does not improve system performance.
6. Correct Answers: A and B
A. Correct: The settings selected on the Schedule tab are correct to launch the task
every Sunday at 1:00 A.M.
B. Correct: Selecting a Domain Admin account is the best way to ensure that a
scheduled task copied to many different systems has local Administrator rights on
all systems. If a Domain Admin account is not used, a local Administrator account
must be selected for each individual system—and account names and passwords
might vary.
C. Incorrect: The proper method for ensuring that scheduled tasks do not interfere
with user sessions is to select the Only Start The Task If The Computer Has Been
Idle For At Least check box from the Settings tab of the Task Properties dialog box.
D. Incorrect: The Wake The Computer To Run This Task check box was not
selected while the task was being configured. This check box is located on the Settings
tab of the Task Properties dialog box.
E. Incorrect: This desired result was not accomplished. To ensure that the scheduled
task does not consume the system’s battery, select both the Don’t Start The
Task If The Computer Is Running On Batteries and Stop The Task If Battery Mode
Begins check boxes from the Settings tab of the Task Properties dialog box.
7. Correct Answers: D
A. Incorrect: The Scheduled Tasks graphical administrative utility is capable of
modifying tasks created with the AT command. Further, AT cannot display the
task because tasks that have been modified by the Scheduled Tasks are not visible
to AT.
B. Incorrect: The Scheduled Tasks graphical administrative utility can update tasks
created with the AT command, but makes the tasks invisible to the AT commandline
utility after they have been modified.
