Installing, Configuring, and Administering Microsoft Windows
XP Professional |
QUESTION 1 You are the administrator for your company. You have just installed Windows
XP Professional on a portable computer for a user named Andrew.
The computer is configured to have a modem and Ethernet PC card.
At the office, Andrew uses his computer in a docking station.
At home, he uses his computer in an undocked state by using
the power adapter. Andrew travels to customer locations frequently.
While traveling, he creates and edits documents. When he returns
from a customer location, he information you that the battery
power in his computer has not lasted as long as he would like.
You need to configure Andrew's portable computer to conserve
battery power for his sales trips. What should you do?
A. Modify the Device Manager settings to disable all devices used by the docked
hardware profile
B. Restart the computer in the undocked profile. In control panel, disable the
server service in the services options
C. Configure the hardware profiles so that the Undocked hardware profile is at
the top of the list of available hardware profiles.
D. Create a new hardware profile named Remote. Use Device Manager to disable
the modem and Ethernet PC card devices for this hardware profile.
Answer: D.
Explanation: A hardware profile is used to store the configuration
settings for a set of devices and services that are used on
a computer. In Windows XP Professional you can create different
hardware profiles to meet a user's needs in different situations.
The user can then choose the appropriate profile the Windows
XP Professional should load when starting the computer. To ensure
the optimal performance in different networking environments,
we should create different hardware profiles that the users
can choose from under different network environments. In this
scenario we should create a profile that has the modem and Ethernet
card disabled to save the battery resources used to power these
cards. The user can then choose this profile when he is visiting
client sites
Incorrect Answers:
A: Windows XP Professional automatically creates separate hardware profiles for
portable computers for when they are docked and when they are
undocked. The appropriate profile is automatically selected
by the operating system when the computer is booted while in
docked state and when it booted while in undocked state.
B: Disabling the server service will not save any battery power as it is a service
and not a device. Devices consume power. Furthermore, by disabling
the server service other user will not be able to connect to
any shared drive or folder on our computer but we will still
be able to access shared folders on other computers.
C: The modem and Ethernet card are enabled in the undocked profile. When you
have a docked and undocked profile, the undocked profile will
be loaded by default if the computer is undocked. The same goes
for the docked profile when the computer is docked. Therefore
the order in which they appear in the hardware profiles list
would not make any difference.
QUESTION 2 You are the desktop administrator for your company. You install Windows XP
Professional on your portable computer. The computer is configured
to use an IEEE 1394 PC card. You use the computer to download
pictures from a digital camera while you are at the office.
You attend a meeting every Monday. During the meeting you use
a battery to supply power to your portable computer. Occasionally,
the battery runs out of power during these meetings. You need to configure the computer to conserve battery
power while you attend your weekly meeting without affecting
your power options when you use the computer at your office.
How should you configure your computer?
A. Use Device Manager to disable the IEEE 1394 PC card power device.
B. In control panel, select the Minimal Power Management power scheme in the
Power Options Properties.
C. Create an additional hardware profile, and disable the IEEE 1394 PC card for
this profile.
D. Use Device Manager to configure the IEEE 1394 PC card Host Controller power
management scheme. Select the Allow this device to bring the
computer out of standby check box.
Answer: C.
Explanation: To ensure the optimal performance in different
networking environments, we should create different hardware
profiles that the users can choose from under different network
environments. We do not require the IEEE 1394 PC card at the
meeting therefore we should create a profile that has the IEEE
1394 PC card disabled to save the battery resources used to
power this card. We can then choose this profile when we are
at the meeting.
Incorrect Answers:
A. Using Device Manager to disable the IEEE 1394 PC card would disable the device
in the current profile. We should create a new profile by copying
the current profile, provide a name for the copied profile and
select the new profile when we reboot the computer. We can then
disable the device in the new profile and will be able to select
the new profile when we boot the computer at the meetings.
B. In the Minimal Power Management power scheme, some power management features,
such as timed hibernation or a timed event that can put the
disk drive in a sleep mode, are disabled. This will thus conserve
less battery power than the default power scheme, which is the
Always On power scheme.
D. Configuring a device to bring a computer out of standby mode will not decrease
the device's power consumption. It will only configure the device
to bring the computer out of standby mode when activity is detected
in the device.
QUESTION 3 You are the desktop administrator for the Graphic Design Institute. You have
just deployed new Windows XP Professional computers to all graphic
designers. Each computer has a built-in tape drive for data
backups. The graphic designers need to back up their own data
to the tape drive. You add all graphic designers' user accounts
administrator members of the Backup Operators group on their
computers. Then you instruct the graphic designers to create
a full backup of all their data every Monday morning. The graphic
designers need to back up all of their data once a week. They
also need to back up all the changes since the last full backup.
The graphic designers want to use a backup method that allows
them to recover their data as quickly as possible. What should
you advise the graphic designers to do?
A. Perform a Differential backup every Monday. Create an Incremental backup for
Tuesday, Wednesday, Thursday, and Friday.
B. Perform a Daily backup every Monday. Create an Incremental backup for Tuesday,
Wednesday, Thursday, and Friday.
C. Perform a normal backup every Monday. Create an Incremental backup for Tuesday,
Wednesday, Thursday, and Friday.
D. Perform a copy backup every Monday. Create an Incremental backup for Tuesday,
Wednesday, Thursday, and Friday.
Answer: C.
Explanation: Although none of the answers provided here are strictly correct,
this answer is the best. To back up all the changes that were
made since the last full backup, we would need to perform a
differential backup. A Differential back up only backs up files
and folders that are marked as having been altered since the
last full backup but does not clear these markers. These markers
are called archive bits. Thus, if we performed two differential
backups on a file that has been altered since the last full
back but not since the last differential backup, the file would
be backed up on both occasions. This provides the quickest recovery
method as we would have to restore only the most recent full
backup and the most recent differential backup.
Incorrect Answers:
A: When we perform an incremental backup, the archive bits are cleared and the
files are marked as having been backed up. Thus, if we performed
a second incremental backup on a file that has been altered
since the last full backup but not since the last incremental
backup, that file would not be backed up the second time. Using
incremental backups increases the time required to recover data
as we would need to restore the data from the last full backup,
then from the last differential backup and then all the incremental
backups that were performed since the last differential backup.
These incremental backups would be restored in sequence from
the first to the most recent backup since the last full of differential
backup. Furthermore, we cannot have a backup scheme that only
includes differential and incremental backups; we need to have
a full backup as well.
B: When we perform a daily backup, we backup all the files that have changed
during the day. This type of backup uses the date stamp of each
file to determine which files should be included in the backup
and does not clear the archive bit. The files are thus not marked
as having been backed up. Therefore, if we perform an incremental
backup after performing a daily backup, the files that were
backed up during the daily backup would also be backed up during
the incremental backup. Furthermore, we cannot have a backup
scheme which only includes daily and incremental backups; we
need to have a full backup to have a base.
D: When we perform a copy backup, all the selected files are backed up but the
archive bit is not cleared. The files are thus not marked as
having been backed up. Therefore, if we perform an incremental
backup after performing a daily backup, the files that were
backed up during the daily backup would also be backed up during
the incremental backup. Furthermore, we cannot have a backup
scheme which only includes daily and incremental backups; we
need to have a full backup to have a base.
QUESTION 4 You are the desktop administrator for your company. All users have Windows
XP Professional or Windows 2000 Professional computers. Users
in the accounting department run an application that requires
several hours to process financial and accounting data. Users
in the accounting department report that when they run this
application, the performance of other business applications
becomes significantly slower. You need to allow the accounting
application to run with the least amount of performance impact
on the other business applications. How should you configure
the users' applications?
A. Configure all other business applications to have High priority.
B. Configure all other business applications to have Realtime priority.
C. Configure the accounting application to have Above Normal priority.
D. Configure all accounting application to have Below Normal priority.
Answer: D.
Explanation: To resolve the problem in this scenario we must
lower the priority of the accounting application. The priority
must be lowered from Normal to either Low or to Below Normal.
This will result in less system resources being allocated to
the application and will leave more resources for other processes.
This would thus improve the performance of the other applications
while allowing accounting application to run.
Incorrect Answers:
A: It would be best to lower the priority of the accounting application, rather
than increase the priority of other applications because this
could adversely affect the running of normal system processes.
By lowering the priority of the accounting application, less
system resources will be allocated to the accounting application
and more system resources will be available the other processes.
B: It would be best to lower the priority of the accounting application, rather
than increase the priority of other applications because this
could adversely affect the running of normal system processes.
By lowering the priority of the accounting application, less
system resources will be allocated to the accounting application
and more system resources will be available the other processes.
C: It would be best to lower the priority of the accounting application, rather
than increase the priority of other applications because this
could adversely affect the running of normal system processes.
By lowering the priority of the accounting application, less
system resources will be allocated to the accounting application
and more system resources will be available the other processes.
QUESTION 5 You are the desktop administrator of your company. A user named Andrew has
just dropped his Windows XP Professional portable computer on
the floor. Andrew reports that when he turns on his portable
computer, he receives the following message: "System disk not
found." You confirm that the hard disk on Andrew's computer
is functioning properly. The portable computer has an Automated
System Recovery (ASR) backup of the original system state. You
verify that Andrew had created a restore point before the accident.
You need to ensure that Andrew's computer can start Windows
XP Professional from the hard disk. What should you do?
A. Restart the computer with the last known good configuration
B. Restart the computer in safe mode. Restore Windows XP Professional by using
the latest restore point.
C. Restart the computer by using a Windows XP Professional CD. Perform an ASR
restore.
D. Restart the computer by using a bootable floppy disk. Restore the operating
system by using the Ntbackup utility and the latest ASR backup.
Answer: C.
Explanation: Windows XP Professional introduces the Automated
System Recovery (ASR) tool, an advanced option of the Backup
Tool (NTBackup.exe). ASR replaces the Emergency Repair Disk
found in Microsoft Windows 2000 and Microsoft Windows NT 4.0.
ASR in Backup is a last-resort feature to use before reformatting
your disk and re-installing Windows XP Professional. ASR enables
you to restore the system state and critical files on the system
and boot partitions. Use ASR only when Windows XP Professional
cannot start in normal, safe, or Recovery Console mode. To restore
your system by using ASR, ensure that your computer is set in
the BIOS to boot from the CDROM. Insert the Windows XP Professional
installation CD, and then restart your computer. At the Press
any key to boot CD prompt, press any key. At the ASR prompt,
press F2. At the prompt, insert an ASR floppy disk. At the prompt,
insert ASR backup media (typically one or more pieces of removable
media such as data tape cartridges). At this prompt, provide
a destination folder, such as C:\Windows or C:\Winnt.
Incorrect Answers:
A. The system disk holds the files required to boot the computer. The computer,
however, cannot locate system disk. We therefore cannot boot
the computer and will thus not be able to access advanced boot
options of which Last Known Good Configuration is an example.
B. The system disk holds the files required to boot the computer. The computer,
however, cannot locate system disk. We therefore cannot boot
the computer and will thus not be able to access advanced boot
options of which Safe Mode is an example.
D. ASR restores critical boot and system partition files. The correct procedure
to restore your system by using ASR is to ensure that your computer
is set in the BIOS to boot from the CD-ROM. Insert the Windows
XP Professional installation CD, and then restart your computer.
At the Press any key to boot CD prompt, press any key. At the
ASR prompt, press F2. ASR cannot be started from a bootable
floppy disk.
QUESTION 6 You are a help desk technician for your company. Susan is an executive. Because
Susan travels frequently, she uses a Windows XP Professional
portable computer that has a smart card reader. Susan asks you
to configure her computer so that she can dial in to the company
network when she is out of the office. Company security policy states that dial-in users must use a smart
card when they connect to the network, and that the users must
use the strongest form of data encryption possible. Company
security policy also states that client computers must disconnect
if the routing and remote access server does not support both
smart card authentication and the strongest possible authentication.
You need to configure the dial-up connection properties on Susan's
computer to dial in to the company network. Your solution must
ensure that company security policies are enforced. Which three
actions should you perform? (Each correct Answer: presents part
of the solution. Choose three)
A. Select the Advanced (custom settings) security option.
B. Select the Require data encryption check box.
C. Select the Typical (recommended settings) security option.
D. Select the Use smart card item from the Validate my identity as follows list.
E. Select the Maximum strength encryption item from the Data encryption list.
F. Select the Allow these protocols option, and select the MS-CHAP v2 check box.
G. Select the Extensible Authentication Protocol (EAP) option, and select Smart
Card or other Certificate from the EAP list.
Answer: A, E, G.
Explanation: Company security policy requires that dial-in users
must use a smart card to connect to the network, must use the
strongest form of data encryption possible and client computers
must disconnect if the routing and remote access server does
not support both smart card authentication and the strongest
possible authentication. Therefore we should configure the dial-up
connection properties on Susan's computer by selecting the advanced
settings to set specific protocols and other options. We must
then select the Extensible Authentication Protocol (EAP) option
and select Smart Card or other Certificate from the EAP list.
This will enable smart card authentication. We must then select
the Maximum strength encryption item from the Data encryption
list to ensure that only the maximum security is used. This
will ensure that client computers will disconnect if the routing
and remote access server does not support both smart card authentication
and the strongest possible authentication.
Incorrect Answers:
B: By select the Require data encryption check box we will ensure that some form
of encrypted authentication occurs but we will not ensure that
maximum strength encryption is used.
C: The Typical (recommended settings) security option does not use maximum strength
encryption.
D: The Use smart card item in the Validate my identity as follows list will not
ensure that only the maximum strength encryption is used, you
have to edit the advanced properties.
F: MS-CHAP v2 is not the highest form of encryption.
QUESTION 7 You are a help desk technician for your company. Stefan and Irene are software
developers for your company. Stefan is developing a Web application
on his Windows XP Professional computer. The computer is named
Stefan132. When Irene types http://Stefan132 in the address
bar of her Web browser, she cannot access the Web application
by typing http://localhost or http://Stefan132 in the address
bar of her Web browser. She can access other resources on the
company network. When you run the Ping command from your computer,
you cannot connect to Stephan's computer. When you attempt to
access http://Stefan132 from your computer, Internet Explorer
displays "DNS or Server error." You need to ensure that Irene
can access the Web application on Stefan's computer. First,
you establish a Remote Assistance connection to Stefan's computer.
What should you do next on Stefan's computer?
A. Run the Ipconfig/renew command.
B. Stop and then restart the World Wide Web Publishing service.
C. Ensure that the Everyone group Allow-Full Control permission on the Inetpub
folder.
D. In the properties of the Local Area Connection clear the Internet Connection
Firewall Check box.
Answer: D.
Explanation: When an expert attempts to connect to a novice's
computer, the expert may receive the following error message:
A Remote Assistance connection could not be established. You
may want to check for network issues or determine if the invitation
expired or was cancelled by the person who sent it. This problem
can occur if the Internet Connection Firewall has been enabled
after the Remote Assistance invitation was created. To resolve
this problem, we should either create a new Remote Assistance
invitation while ICF is enabled, and then send the new invitation
to the expert; or we should disable the Internet Connection
Firewall while the expert attempts to establish the Remote Assistance
invitation; or restart the novice's computer, and then have
the expert establish the Remote Assistance session. Incorrect
Answers:
A: The Ipconfig/renew command is used to renew the client computer's IP address
lease from a DHCP server. It will not resolve a Remote Assistance
connection problem.
B: In this scenario the pings are being blocked therefore it is more likely a
firewall problem. Restarting the World Wide Web Publishing service
will not solve this problem
C: For security reason we should not give the Everyone group Full Control permission
on the inetpub folder.
QUESTION 8 You are a help desk technician for your company. Helene is a user in the sales
department who works from home. She reports a problem on her
Windows XP Professional computer. You instruct Helene to send
you a Remote Assistance invitation, and then disconnect from
the ISP. You receive the invitation on your Windows XP Professional
computer and instruct Helene to reconnect to her ISP. After
you accept the invitation, you cannot connect to Helene's computer.
You need to establish a Remote Assistance connection with Helene's
computer. What should you do?
A. Run the Ipconfig/flushdns command on your computer, and reaccept the invitation.
B. Run the Remote Desktop Connection application on your computer to establish
a connection to Helene's computer.
C. Instruct Helene to disable the Internet Connection Firewall on her computer.
From your computer, reaccept the invitation.
D. Instruct Helene to send a new Remote Assistance invitation and remain connected
to her ISP. From your computer, accept the new invitation.
E. Instruct Helene to edit the System properties of her computer and add your
domain user account to the Remote Desktop Users list on the
Remote tab. From your computer, reaccept the invitation.
Answer: D.
Explanation: In this scenario Helene needs to remain connected
to her ISP so that we can connect to her computer via the Internet.
We should therefore instruct Helene to send a new Remote Assistance
invitation and remain connected to her ISP. We can then accept
the new invitation and connect to her computer from our computer.
Incorrect Answers:
A: The Ipconfig/flushdns command is used to remove all IP configuration entries
from the cache. This is useful when we encounter name resolution
problems that result from the server being restarted after we
have accessed the server. This however is not the case in this
scenario. The problem in this scenario is that we have cannot
connect to Helene's computer as she has disconnected from her
ISP.
B: We cannot run the Remote Desktop Connection application on our computer to
establish a connection to Helene's computer as she is not connected
to the Internet; she has disconnected from the ISP.
C: A firewall is not preventing us from accessing Helene's computer. We have
no connection to her computer as she has disconnected from the
ISP.
E: It is not necessary for Helene to add our domain user account to her Remote
Desktop Users list as she has sent an invitation. She has however
disconnected from the ISP, therefore we cannot establish a connection
to her computer.
QUESTION 9 You are a help desk technician for your company. The network consists of a
single Active Directory domain. The network includes Windows
2000 Advanced Server computers, and Windows 2000 Professional
and Windows XP Professional client computers. Except for the
domain controllers, all computers on the network use DHCP for
their TCP/IP configuration. During the business day, the network
administrators perform emergency maintenance on a file server
named Filesrv1. Filesrv1 is then restarted and experiences no
further problems. Users begin reporting that when they try to
access resources on Filesrv1, they receive the following error
message: "Network path not found." You verify that Filesrv1
is functional. You need to ensure that all users can access
Filesrv1. What command should you instruct users to run?
A. Nbtstat -R
B. Nbtstat -RR
C. IPconfig /flushdns
D. IPconfig /registerdns
Answer: C.
Explanation: The likely problem in this scenario is that when
the file server was restarted, it received a new IP address.
When a user connects to a server using a user-friendly name,
DNS resolves the user-friendly name to an IP Address that is
then used to connect to the server. This name-to-IP address
resolution is then stored in cache on the user's computer so
that when they attempt to connect to the same server, they do
not have to use DNS. The DNS cache on the users' computers has
the old IP address for the file server. Thus, when the client
attempts to contact the file server it is using the wrong IP
address that it has cached. The /flushdns switch of the Ipconfig
command flushes the list of locally cached DNS names.
Incorrect Answers:
A: Nbtstat -R command are WINS command that is used to flush the NetBIOS name-to-IP
Address cache. In a Windows 2000/XP environment, we do not use
NetBIOS names but host names which requires a DNS server rather
than WINS server. The Nbstat command would thus be inappropriate.
B: Nbtstat commands are used to resolve NetBIOS name resolution problems and
are related to WINS servers. In a Windows 2000/XP environment,
we would be using DNS servers rather than WINS servers for name
resolution purposes.
D: The IPconfig/registerdns command will register the users' addresses in DNS.
This will not flush the DNS cache on the users' computer and
thus will not resolve the problem.
QUESTION 10 You are a help desk technician for your company. An employee name Marc is
attempting to open a Microsoft Word document Phonelist.doc by
using Internet Explorer. However, when he types http://Server1/Files/Phonelist.doc
into the address bar in Internet Explorer, he receives the following
error message: "404: Page not found." You verify that Phonelist.doc
exists in a shared folder named Files on Server1. You need to
ensure that Marc can access Phonelist.doc by using Internet
Explorer. What should you do?
A. Instruct Marc to run the IPconfig/flushdns command on his computer.
B. Grant Marc's domain user account Allow-Read permission on the File shared
folder.
C. Grant Marc's domain user account Allow-Read permission on Phonelist.doc.
D. Instruct Marc to type file://server1/File/Phonelist.doc into the address bar
in Internet Explorer.
Answer: D.
Explanation: The error message 404 indicates that the Web page
cannot be located at the URL address specified by the user.
This is because the user specified a Web server address, which
is denoted by http:// in the URL. He should use file:// in the
URL to specify a file server. The correct URL for opening the
file with a Web browser in this scenario is file://server1/File/Phonelist.doc.
Incorrect Answers:
A: The IPconfig/flushdns command is used to clear the DNS cache on the user's
client computer. This command is useful for when the server
has been restarted and has a new IP address that does not match
the one held in cache on the user's client computer. This command
will not aid the user in opening a file in a Web browser, particularly
as the user has not specified the URL correctly.
B: If Marc did not have the required permissions to the file, he would have received
an access denied error, not a page not found error.
C: If Marc did not have the required permissions to the file, he would have received
an access denied error, not a page not found error.
