Objective 3.6 Questions
1. You manage the computers for the graphic artists in your company, many of whom
regularly use 3-D rendering software to create computerized special effects for promotional
videos. Their standard workstations include dual CPUs running at 3 gigahertz, 1
gigabyte of RAM, and a high-end video card with built-in 3-D graphics acceleration.
One of the artists complains that her workstation periodically performs poorly. You log
performance data from several of the computers while the artist who is experiencing
diminished performance continues to work. You see the following processor-related
statistics for that system:
■ The Processor object’s % Processor Time counter averages 85 percent.
■ The Processor object’s Interrupts/Sec counter averages 6,500.
■ The Memory object’s Pages/Sec counter averages 1.5.
■ The System object’s Processor Queue Length counter averages 1.8.
Which of the following is the likeliest cause of diminished performance? Choose the
best answer.
A. Processor object’s % Processor Time
B. Processor object’s Interrupts per second
C. Memory object’s Pages/Sec
D. System object’s Processor Queue Length
2. Yesterday, one of the developers at your company purchased a second processor for
his dual processor Windows XP Professional computer. Although he knows he should
contact you for hardware upgrades, he was excited about the performance boost and
installed the processor himself after hours. The first time he started his computer after
adding the processor, he received a Stop error (which he referred to as a Blue Screen).
He left his computer in that state until you arrived the next morning to help him troubleshoot
the problem. The Stop error information was 0x00000079 MISMATCHED_HAL.
He wants you to enable Windows XP to start successfully using both processors without
opening the computer’s case again. What is the best way to solve the problem?
Choose the best answer.
A. Start Windows XP in safe mode. Open the System Properties dialog box and click
the Hardware tab. Click the Hardware Profiles button, and create a new profile for
the multiprocessor configuration. Then, restart Windows XP in normal mode.
B. Insert the Windows XP Professional CD-ROM and reinstall Windows XP Professional
over the existing installation.
