The report view offers a logical view of how many counters at once?
This view is useful for showing all of the counters that are being tracked through the System Monitor.
To see an what applications are active on your computer, and to get a view of CPU and memory usage, you must first configure the Task Manager -- True or False?
False, the Task Manager doesn't require that you first configure the collection of this data; it's gathered automatically.
What is a baseline?
A snapshot of how your system is currently performing.
How do you configure the properties of the System Monitor.
By clicking on the Properties button on the toolbar.
What utility will let you view current data or data from a log file?

To keep track of when a specific counter exceeds or falls below a specified value, what would you define.
An alert.
Since Windows XP is a self-tuning operating system, there's no point in creating baselines at regular intervals of typical usage -- True or False
Processor Interrupts/Sec shows the average number of hardware interrupts received by the processor each second. If this value is more than 3,500, on a Pentium-based computer, what does this mean?
If Processor Interrupts/Sec is above 3,500 it might mean you have a problem with a program or hardware that is generating spurious interrupts.

Counter logs can be configured to occur manually or on a predefined schedule.
In the System Monitor, a Value bar appears by default under the two available graph views (chart and histogram). In the Value bar, which field shows the most current data?
Believe it or not, it's the field labeled "Last." Confusingly enough, reading left to right, the "Last" field appears first. (Why ask why?)

1) Average disk access time on your hard drive
2) The speed of your disk controller.
Tweaks may cause more problems then they solve, true or false?
What is the most likely cause of system bottlenecks.
When you have no idea what is causing a system bottleneck, memory is a good place to start checking.
In addition to the most current data, what other values can be tracked for a given counter in the System Monitor?
1) Average
2) Minimum (the lowest recorded value)
3) Maximum (the highest recorded value), and
4) Duration, showing how long the counter has been tracking data.

Disk access is the amount of time your disk subsystem takes to retrieve data that is requested by the operating system.
Name five system resources tracked as performance objects in the System Monitor.
Cache, Memory, Paging File, Process, Processor, PhysicalDisk, are some.
What is paging?
Swapping between the page file on the hard disk and physical RAM.
What is a bottleneck?
A system resource that is inefficient compared with the rest of the computer system as a whole.
If the %DiskTime counter indicates that the physical disk is busy more than 90 percent of the time, how can you improve performance?
By adding another disk channel and splitting the disk I/O requests between channels.
What do you need in order to be able to view performance of counters on remote computers using the System Monitor?

They can be configured so that a message is sent, a program run, or a more detailed log file is generated.
The histogram view in the System Monitor is useful for showing system performance over time -- True or False?
False. The histogram view shows data only for the current period. You do not see a record of performance over time, as you do with the chart view.
What is Windows XP's built-in mechanism for monitoring an entire network?
There isn't one. However, you can monitor and optimize traffic generated by a specific Windows XP computer.
In the System Monitor, what are counters?
They are used to track specific information regarding a performance object.
What counter measures how much physical memory is available? And when do you know you need more?
Available MBytes. If this number is less than 4MB, you should consider adding more memory.
By clicking the appropriate button on the System Monitor toolbar, you can see your data in what three views?
Chart view
Histogram view
Report view
Windows XP supports how many processors?
Up to two.
To monitor your network and spot bottlenecks using the System Monitor, you might use what?
The Pages/Sec counter, a memory metric, shows the number of times the requested information was not in memory and had to be retrieved from disk. For good performance this counter should be below what value?
This counter's value should be below 20, and for optimum performance is should be 4 or 5.
If you are creating baselines on a regular basis, what can you identify proactively?
System trends.
If your counters indicate that you have a disk subsystem bottleneck, the first thing to do is install a faster or larger disk drive -- True or False?
No. You should begin by making sure you don't have a memory deficiency. Insufficient memory can cause excessive paging, which in turn effects the disk subsystem.
When you first start system monitor, processor time, memory pages per second, and physical disk time are tracked by default -- True or False?
False. When you first start System Monitor, nothing is tracked by default.
In addition to defining alerts, through the Performance Logs and Alerts snap-in, you can create two types of logs? What are they?
Counter logs
Trace logs
An "instance" is a mechanism that allows you to track the performance of a specific object when you have more than one associated with a specific performance object. Give an example.
Suppose your computer has two physical disk drives. When you track the PhysicalDisk performance object, you can track both of your drives, or you can track drive 0 and drive 1 separately.
Distinguish between the PhysicalDisk and LogicalDisk objects.
The PhysicalDisk is the sum of all logical drives on a single physical drive. The LogicalDisk object represents a specific logical disk or partition.
The Performance Logs and Alerts snap-in can be accessed from the MMC. How else can you find it?
Start>Control Panel>Administrative Tools>Performance. Add the snap-in from the console, if it is not already added.
You use the Performance Logs and Alert snap-in to view performance logs -- True or False?
False: You use the System Monitor to view the data collected in performance logs.
To determine how memory is being used, what two areas need to be examined?
Physical RAM and Logical memory that exists on the hard drive, also called the Page File.
What two disk subsystemn performance objects can be measured using system monitoring tools?
The PhysicalDisk object, and the LogicalDisk object.
If you are using excessive paging, is this a sign that you need more hard-disk storage?
No, if you're system is doing this, it's a clear sign that you need more physical RAM.
If, after checking, you find out you have enough memory, and you still have a disk subsystem bottleneck, what are your options?
1) Use faster disks and controllers
2) Use disk striping to take advantage of multiple I/O channels
3)Balance heavily used files on multiple I/O channels
4) Add another disk for load balancing.
The Graph tab of the System Monitor dialog box has four options that can be applied to a chart or histogram view. What are they?
1) A title
2) A vertical axis label
3) Whether to show a vertical grid, horizontal grid, and/or vertical scale numbers, and
4) The minimum and maximum numbers for the vertical scale.
If you have a processor bottleneck, what can you do?
1) Use applications that are less processor-intensive.
2) Upgrade your processor.
3) If your computer supports multiple processors, add one.
How much memory is too much?
You can never have enough memory. It's actually a good idea to have more than you think you will need just to be on the safe side.
What are the two most important counters for monitoring the system processor?
%Processor time and Interrupts/Sec
To measure data continuously, and/or to track data collected by the operating system or programs, what type of log would you use.
Trace logs.
An extra processor will help alleviate processor bottlenecks on what kind of applications?

%Usage is a counter that indicates the percentage of the allocated page file that is currently in use. You may need more memory is this number is consistently above what percentage?
Can you monitor the amount of free disk space on a logical disk?
Yes, through the %Free Space Counter.
Performance objects are usually tracked using microprocessors -- True or False.
False. Performance objects such as memory or processors, are monitored by counters and alerts.
In Windows XP Professional, to enable disk counters you must execute the DISKPERF -Y command -- True or False?
