QUESTION 1:
You work as the network administrator at Certkiller .com. The Certkiller .com
network consists of a single Active Directory domain named Certkiller .com. All
servers on the Certkiller .com network run Windows Server 2003 and all client
computers run Windows XP Professional.
A member server named Certkiller -SR12 is an application server on your
network. An application hosted on Certkiller -SR12 is a mission-critical
application used by all users on the network. You have only recently installed the
application, but since then you have had to restart Certkiller -SR12 on numerous
occasions. You notice that user complaints tend to increase during peak business
hours.
You are assigned to monitor and track the performance of Certkiller -SR12. You
want to monitor the server to determine whether there is an existing bottleneck, and
you to perform all monitoring in real-time. Your monitoring effort should indicate
whether you need to move some applications to another application server on the
network.
What should you do? Choose two correct answers. Each correct answer presents a
complete solution to achieving your goal. Choose two.
A. Use System Monitor to monitor the Process: % Processor Time performance counter.
B. Use Task Manager to view the information on the Processes tab.
C. Open Event Viewer and examine the system log.
D. Use System Monitor to monitor the trace log.
Answer: A, B
Actualtest.org – The Power of Knowing
Explanation: Each process running on Certkiller -SR12 will have its own instance
of the Process: % Processor Time performance counter. This is the counter which
indicates the amount of time the CPU is executing instructions for the threads of the
specific process. Both System Monitor and Task Manager would display this
information to you, and it would be displayed in real-time.
Incorrect answers:
C: If you open Event Viewer and examine the system log, you will be presented with
operating system-specific event information.
D: Trace logs cannot track CPU usage on a server. They respond to specific events
occurring.
QUESTION 2:
Exhibit
You work as the network administrator at Certkiller .com. The Certkiller .com
network consists of a single Active Directory domain named Certkiller .com. All
servers on the Certkiller .com network run Windows Server 2003. Certkiller .com
employs a server named Certkiller -SR02 to run an application named
Certkiller App3.
A Certkiller .com employee named Andy Reid works in the Research and
Development department. One morning Andy Reid complains that that
Certkiller App3 is performing slowly. You immediately suspect that an unauthorized
application is installed on Certkiller -SR02. After running the netstat command,
you are presented with the output displayed in the above exhibit.
Which of the following is the tool that will allow you to use the output from the
netstat command to identify the unauthorized application?
A. Performance console
B. System monitor
C. Network Monitor
D. Task manager
Answer: D
Explanation:
Task Manager offers you a quick glimpse at the following items: Applications currently
in use, Processes currently running, current processor usage, Current paging file usage,
Actualtest.org – The Power of Knowing
overall current memory usage, Current network utilization and currently logged-on users.
Incorrect answers:
A: Performance MMC snap-in is a utility for monitoring, tracking, and displaying a
computer’s performance statistics, both in real time and over an extended period for
establishing a system baseline. This console includes the System Monitor node and the
Performance Logs and Alerts node.
B: System Monitor is a node in the Performance MMC snap-in for monitoring and
logging computer performance statistics using performance objects, counters, and
instances.
C: You should be using the Network Monitor tool to manage large network traffic
situations.

QUESTION 3:
You work as the network administrator at Certkiller .com. The Certkiller .com
network consists of a single Active Directory domain named Certkiller .com. All
servers on the Certkiller .com network run Windows Server 2003 and all client
computers run Windows XP Professional.
A member server named Certkiller -SR34 is an application server on your
network. You are assigned to monitor the performance of Certkiller -SR34. An
application hosted on Certkiller -SR34 is used during the day, by users working in
various departments. You have only installed the application last week, but since
then you have had several complaints about the poor performance of
Certkiller -SR34.
You want to monitor Certkiller -SR34 to determine whether there is an existing
bottleneck. You open System Monitor to view performance data collected on
Certkiller -SR34. The exhibit shows the performance object counter values over
the past few weeks.
What should you do to improve the performance of Certkiller -SR34?
A. Add an additional CPU.
Actualtest.org – The Power of Knowing
B. Add additional RAM.
C. Replace the current network adapter with a faster network adapter.
D. Replace the current hard disk with a faster one.
E. Schedule the application to run during off peak hours.
Answer: D
Explanation: The Physical Disk: % Disk Time counter indicates the percentage of
time that a drive is active, and has a threshold of 85 percent. In your case, the
counter is fairly high at 85%, and there are ten requests waiting in the queue. This
is unacceptable server disk subsystem performance. These counters are the only
ones that point to a server bottleneck condition. You should consider upgrading
your disk to a faster one, or you should install additional disks.
Incorrect answers:
A: The Processor: % Processor Time counter can be used to detect a process which is
utilizing over 85 percent of the processor time. In this case, the current value of the %
Processor counter (25%) does not indicate a processor issue. An average over 85% would
indicate a CPU bottleneck.
B: TheMemory: Pages/sec counter indicates the rate at which pages are written to disk,
or read from disk. With a recommended counter threshold of 20 or below 30, depending
on your computer, your current counter value is acceptable at 5. The Memory: Page
Faults/sec counter would give you an idea of the rate at which page faults are occurring.
An acceptable counter value for Memory: Page Faults/sec is 150.
C: Currently, the counter shows an acceptable rate of network traffic.
E: There is no need to schedule the application to run at night. Users need to run the
application during the day, which can be made possible by replacing your disk with a
faster one.
