QUESTION 124:
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.
Certkiller .com consists of a three-node Network Load Balancing (NLB) cluster. Each
of the three-node (NLB) cluster consists of a network adapter. The Certkiller .com
network contains a computer named Certkiller -SR44. You have received
instructions to join Certkiller -SR44 to the cluster. You then join one of the nodes
to the cluster, but the attempt fails. You need to join the node to the cluster.
What should you do?
A. Let multicast mode be configured on the cluster.
B. On Certkiller -SR44 you should set the filtering mode to Multiple host.
C. On Certkiller -SR44 you should set the filtering mode to Single host.
D. Let unicast mode be configured on the cluster.
Answer: A
Explanation: If you would have used unicast mode you cannot communicate from
one node in the cluster to another node in the same cluster. Therefore you need to
use multicast mode.
Incorrect answers:
B, C: Filtering is inappropriate to the ability of nodes to communicate within a cluster.
D: If you would have used unicast mode the adapter would assign a new MAC address.
With the unicast mode you cannot communicate from one node in the cluster to another
node in the same cluster. Therefore you need to use multicast mode.
QUESTION 125:
You work as the network administrator at Certkiller .com. The Certkiller .com

Actualtest.org – The Power of Knowing
network consists of a single Active Directory domain named Certkiller .com. All
servers on the Certkiller .com network run Windows Server 2003. Half the client
computers run Windows 2000 Professional, and the rest run Windows XP
Professional.
The Certkiller .com network contains two domain controllers named
Certkiller -DC01 and Certkiller -DC02 which run DNS services. The zones of
Certkiller -DC01 and Certkiller -DC02 are used to store the zone information in
AD rather than in flat text files. Certkiller .com also contains a DHCP server named
Certkiller -SR16. The users get their IP addresses and their configurations from
this server.
Certkiller .com contains a Marketing department. The working hours of the users
are from 8:00 AM to 5:00 PM. Due to company growth, the company now contains
more than triple the amount of employees.
After the last employment of employees, the users in the Marketing department
complain that it takes them a long time to log on to the network. You need to use the
System Monitor to identify the problem.
What should you do?
A. On each of Certkiller -DC01, Certkiller -DC02 and Certkiller -SR16 you should
create a performance alert for Processor\%Processor Time, Memory\Available Bytes,
Server\Bytes Received /sec counters, and Network Interface/Output Queue Length.
B. On Certkiller -DC01, Certkiller -DC02 and Certkiller -SR16 between 8:00 AM
and 9:00 AM you should create a performance log for Processor\%Processor Time,
Memory\Available Bytes, Memory\Page /sec counters, and Network Interface/Output
Queue Length.
C.
On Certkiller -DC01, Certkiller -DC02 and Certkiller -SR16 between 8:00 AM and
9:00 AM you should create a performance log for Processor\%Processor Time,
Memory\% Committed Bytes in Use Memory\Page /sec counters, and Network
Interface/Output Queue Length.
D. On each of Certkiller -DC01, Certkiller -DC02 and Certkiller -SR16 between
8:00 AM and 9:00 AM you should create a performance alert for Processor\%Processor
Time, Memory\% Committed Bytes in Use counters, and Network Interface/Output
Queue Length.
Answer: B
Explanation: To find the cause of the problem you should get the information on
each server. To do this you do need to create log on Certkiller -DC01,
Certkiller -DC02 and Certkiller -SR16. Processor\%Processor Time is used to
see if a processor bottleneck occurs. Memory\Available Bytes is used to see the
number of bytes available to be assigned. Memory\Page /sec counters, tells you if
you need more RAM. Network Interface/Output Queue Length shows the output
packet queue length in the number of packets awaiting transmission.
Incorrect answers:
A, C, D: Memory\% Committed Bytes in Use counters will not indicate if there is a

Actualtest.org – The Power of Knowing
memory bottleneck. The Memory\Page /sec counters include hard faults and soft faults. If
there are a large number of soft faults, it does not indicate a memory bottleneck. Alerts
will cause an action. They are not useful to gather information.
QUESTION 126:
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. Half the client
computers run Windows 2000 Professional, and the rest run Windows XP
Professional.
The Certkiller .com consists of two departments, the Research department and the
Marketing department. Certkiller .com also has 1,500 employees. The Certkiller .com
network contains four file servers named Certkiller -SR11, Certkiller -SR22,
Certkiller -SR33 and Certkiller -SR44 which run Microsoft Windows Server
2003, Standard Edition. You have designed a critical in-house database application
which is used on these servers.
During routine monitoring you discover that the performance of the file servers is
very slow when users access the files over the Internet. During one of the busy hours
you used the System Monitor on the file servers to identify the problem.
Which of the following indicates a hard disk bottleneck?
A. Server name: Certkiller -SR11
%Disk Time: 80
%Idle Time: 25
Average Disk Queue Length: 1,003
Current Disk Queue Length: 1,047
B. Server name: Certkiller -SR22
%Disk Time: 95
%Idle Time: 5
Average Disk Queue Length: 0,985
Current Disk Queue Length: 2,425
C. Server name: Certkiller -SR33
%Disk Time: 100
%Idle Time: 5
Average Disk Queue Length: 2,385
Current Disk Queue Length: 1,982
D. Server name: Certkiller -SR44
%Disk Time: 95
%Idle Time: 15
Average Disk Queue Length: 1,058
Current Disk Queue Length: 0,997
Answer: C

Actualtest.org – The Power of Knowing
Explanation: Certkiller -SR33 shows that the hard disk has a performance
bottleneck. If the Average Disk Queue Length is above 2, it is an indication that it is
waiting to access the disk resources.
Incorrect answers:
A: Certkiller -SR11 has no cause for an alarm.
B: Certkiller -SR22 shows a high % Disk Time and a low %Idle Time. You will also
notice that the Queue Length is not over 2.
D: Certkiller -SR44 shows a high % Disk Time and the %Idle Time is not low. The %
Disk Time can be sometimes misleading.
