|  Nice easy one today!!
Q7. You install Windows 2000 Professional on a computer with two processors. After installing the appropriate applications for your business, you decide to find a baseline for monitoring processor performance. While running multiple applications causing high processor activity, what is the expected range for the processor queue length?
A. 1 - 4
B. 2 - 6
C. 3 - 6
D. 4 - 7
Good Luck - see you tomorrow for the answer!! | |

| Okay, got me on yesterdays question. But I'll go ahead and bite on this one too.
I'll say B. Queue length should range from 1 to 3 threads per processor. Therefore, 2 processors should have a range of 2 to 6.

Correct Answers: B
A. Incorrect: The System object's Processor Queue Length counter on a uniprocessor system with little activity will maintain a queue length average between 1 - 2. Therefore, a range of 1 - 4 does not accurately represent the activity expected on a dual-processor system displaying heavy processor use.
B. Correct: You observe overall processor activity by monitoring the processor queue length and processor use. A sustained queue of several waiting processor requests, combined with consistently high CPU use rate, signals a processor bottleneck. View the System object's Processor Queue Length counter to determine overall processor use on a system. Evidence of a processor bottleneck is indicated by a sustained or recurring queue of more than two threads. Therefore, a range of 2 - 6 threads waiting for processing is the expected range for the system described in the question.
C. Incorrect: A range of 3 - 6 suggests that the computer is heavily overused. This range is unacceptable for sustained periods. Note that the default scale for the System object's Processor Queue Length is 10. Therefore, a Processor Queue Length of 3 will appear as 30 in the Performance snap-in unless you change the scale to 1.
D. Incorrect: A range of 4 - 7 is unacceptable for sustained periods. At this range, the processor or processors might be the bottleneck. Some other reasons for this exessive queue length could be that a device in the computer is raising too many interrupts because of a hardware malfunction, or the computer does not contain enough physical RAM to service the running applications.
Well done Mrfixit!! | |

Must not have been that easy frank. Usually get more response to these questions. |
