QUESTION 1 :
You work as the network administrator at Certkiller .com. The Certkiller .com
network is a single Active Directory network that consists of three subnets as
illustrated in the exhibit. All servers on the Certkiller .com network run Windows
Server 2003 and all client computers run either Windows XP Professional or
Windows 2000 Professional.
Two servers, named Certkiller -SR01 and Certkiller -SR02 respectively, have
Routing and Remote Access enabled. The Certkiller .com helpdesk received reports
from the Certkiller .com users in SubnetA complaining of intermittent problems that
they experience when communicating with a file server named Certkiller -SR12.
Apparently there is no pattern as to when the problem occurs, but when it does
occur, it happens to several clients simultaneously. You have received instruction to
address the matter.
What should you do as the first step in troubleshooting this problem?
A. Run tracert Certkiller -SR12 on a client computer in SubnetA.
B. Run pathping Certkiller -SR12 on a client computer in SubnetA.
C. Use the NetMon utility on Certkiller -SR08.
D. Use the NetMon utility on Certkiller -SR09.
E. Run the route command on both Certkiller -SR08 and Certkiller -SR09.
Answer: C
Explanation: the first port of call in this scenario should be the Network Monitor
(NetMon) utility on Certkiller -SR08 to capture the network traffic. Since the users in
SubnetA are experiencing intermittent problems, the problem most likely related to either
traffic on that subnet or the directly connected router. The NetMon utility will allow you
to capture traffic over a period of time and then you can go back and analyze the traffic
and statistics to determine the cause of the problem. The intermittent nature of the
problem means that you should start by capturing activity over a period of time, to
provide you with a better chance of documenting the failure.
Actualtest.org – The Power of Knowing
Incorrect answers:
A: The tracert command will report any problems with a router being down, but it is not a
useful tool to analyze intermittent problems
B: The pathping command reports packet loss rates at each of the routers on the path. this
tool will allow you to determine which router is causing the problem, but it will not in the
case of intermittent problems as is the case in this scenario.
D: Using the NetMon utility on Certkiller -SR09 will not yield information related to
the problem because Windows Server 2003’s Network Monitor captures only traffic
coming to or from the computer on which it is running.
E: The route command allows you to view and manage a computer’s routing table. This is
used most effectively to configure static routes or to correct corrupted routing table
information. The problem in this scenario is not indicative of routing table problems.
QUESTION 2:
You work as the network administrator at Certkiller .com. The Certkiller .com
network is a single Active Directory network that consists of three subnets as
illustrated in the exhibit. All servers on the Certkiller .com network run Windows
Server 2003 and all client computers run Windows XP Professional.
Two servers named Certkiller -DC01 and Certkiller -DC02 are configured as
domain controllers and run the Domain Name System (DNS) service. The forward
lookup zone is configured as an Active Directory-integrated zone. The
Certkiller .com written security policy states that all client computers should not be
allowed to log on to the domain unless authenticated by a domain controller.
IP configuration for the Certkiller .com client computers are supplied by the Network
Address Translation (NAT) server in SubnetC. The alternate IP configuration is set
Actualtest.org – The Power of Knowing
to default. Both Certkiller -SR07 and Certkiller -SR08 run Microsoft Windows
Server 2003 and Remote Access Service and function as Dynamic Host
Configuration Protocol (DHCP) Relay Agents.
Some of the SubnetA users lodged a complaint that they get very slow response
times when they attempt to access Web sites on the Internet and that they receive a
number of errors when accessing several sites on the Internet. Furthermore the
problem seems to be particularly more acute at certain times of the day.
You received instruction to determine the source of the problem to this end you
need to check whether the performance problem is related to a problem on the
internal network, the ISP, or somewhere else on the Internet.
What should you do?
A. Use the tracert command to reach a host that usually returns errors from a client
computer in SubnetA.
B. Use the pathping command to reach a host that usually returns errors from a client
computer in SubnetA.
C. Use the netstat utility to view TCP/IP statistics on Certkiller -SR06.
D. Use the Netmon utility to capture network traffic on Certkiller -SR06.
Answer: B
Explanation: Since the question mentions that it is not a constant problem and it is
most likely caused by congestion between the hosts in SubnetA and the hosts on the
Internet, you could make use of the pathping command to return information about the
path taken to access a resource and any delays along that specific path. This toll will
show whether the congestion is on the internal network, at the ISP or the Internet.
Incorrect answers:
A: The tracert command will report any problems with a router being down, but it is not a
useful tool to analyze congestion problems.
C: The Netstat Utility used on Certkiller -SR06 in SubnetC will yield information
regarding the sessions currently active on the Certkiller -SR06, but it will not allow you
to pinpoint the location of congestion.
D: The Netmon Utility allows you to capture network traffic on Certkiller -SR06 in
SubnetC with delayed information about the types of packets being sent and received by
Certkiller -SR06. However, it will not yield information that will allow you to
determine which device is causing the congestion.
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. Half the client
computers run Windows 2000 Professional, and the rest run Windows XP
Professional.
Certkiller .com consists of a Research Department which does research for a new
Actualtest.org – The Power of Knowing
application. When the product is finished, it is tested in the Certkiller .com lab. The
successful product is then sold to their clients.
The Certkiller .com network contains two application servers named
Certkiller -SR10 and Certkiller -SR12. Certkiller -SR10 and
Certkiller -SR12 contain critical 16-bit and 32-bit in-house applications, which are
used by the Certkiller .com users and their clients. These two servers are configured
as application server clusters. Certkiller -SR10 acts as the primary server and
Certkiller -SR12 acts as the failover server.
Certkiller -SR10 contains the most used applications and is vital to Certkiller .com.
These two servers are configured with two network adapters. One of the network
adapter acts as a public interface and the other for cluster-to-cluster
communication. On morning the quorum resource disk on Certkiller -SR10 failed.
You need to bring Certkiller -SR10 back online. You also need to take the steps in
sequence? (Select all that apply. Each answer is part of the solution.)
A. On Certkiller -SR12, pause the Cluster service.
B. On Certkiller -SR10 and Certkiller -SR12, stop the cluster service.
C. Use the /forcequorumlog parameter and start the quorum service.
D. Use the /fixquorum parameter and start the quorum service.
E. On Certkiller -SR10, pause the Cluster service.
F. Replace the quorum disk and bring it back online and start the quorum service with the
/resetquorumlog parameter.
G. Use the /debug parameter and start the quorum service.
Answer: B, D, F
Explanation: On both of these servers you need to stop the cluster service to recover
the quorum disk. Because you know that the quorum disk has failed, you can use
the /fixquorum parameter. The final steps is to replace the quorum disk and bring it
back online and start the quorum service with the /resetquorumlog parameter.
Incorrect answers:
A, E: You cannot pause a cluster service to correct a failed quorum disk. You need to
stop these services.
C: The /forcequorumlog parameter is only used to restore quorum the majority quorum
node set loses quorum.
G: The /debug parameter is used to enable diagnostic loggings for the cluster service.
