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.
Actualtest.org – The Power of Knowing
The Certkiller .com domain contains an organizational unit (OU) named Webservers.
The computer accounts of 12 Windows Server 2003 computers that function as
intranet Web servers are located in the Webservers OU. A Group Policy object
(GPO) named WebserverPolicy is linked to the Webservers OU. The GPO is used to
configure various settings on the computers in the OU. A global group named
WebserverAdmins has Administrators local group membership on each intranet
Web server.
Part of your duty includes the installation of a security scanning application on each
intranet Web server. The documentation for the application states that it uses a
service account, which must be able to modify the
HKEY_LOCAL_MACHINE\SYSTEM key in the registry of every computer on
which the application is installed.
You create the service account in the domain. Certkiller .com’s written security
policy states that service accounts must be assigned only the minimum rights and
permissions that they require to function.
You have received instruction from the CIO to complete the following tasks:
1. Configure the intranet Web servers so as to comply with the installation
requirements of the security scanning application.
2. Comply with Certkiller .com’s security policy.
3. Use the least amount of administrative effort.
How will you accomplish the task?
A. You should change the NTFS permissions on the
Systemroot\System32\Config\System file and assign the service account the Allow -
Change permission by configuring the file system security settings in the
WebserverPolicy GPO.
B. You should add the necessary permissions to the registry of each intranet Web server
by running the regedit.exe command.
C. You should configure the necessary permissions as registry security settings in the
WebserverPolicy GPO.
D. You should change the NTFS permissions on the
Systemroot\System32\Config\System file and assign the Allow – Change permission
by running the explorer.exe command.
Answer: C
QUESTION 2:
You work as a network security 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 server named Certkiller -DC21 functions as a domain controller. Authentication
on the Certkiller .com network is performed by Kerberos and the default Kerberos
policy values are used throughout Certkiller .com. A User named Clive Wilson makes
use of a client computer named Certkiller -WS201. Clive Wilson contacted the
Actualtest.org – The Power of Knowing
Certkiller .com helpdesk to report that he is unable to access domain resources from
Certkiller -WS201.
You received instruction to ensure that Clive Wilson is able to access domain
resources. To this end you need to troubleshoot Clive Wilson’s problem. You start
with troubleshooting the authentication process on Certkiller -WS201. Then you
notice that the clock on Certkiller -WS201 is running slow and affecting the
Kerberos authentication process. Comparing the Certkiller -WS201 clock to the
clock on Certkiller -DC21 you also find that the Certkiller -WS201 clock is one
hour slower than Certkiller -DC21’s clock.
What should you do to enable Clive Wilson to access domain resources?
A. Synchronize the Certkiller -WS201 clock with the Certkiller -DC21 clock within a
1-minute difference.
B. Synchronize the Certkiller -WS201 clock with the Certkiller -DC21 clock within a
5-minute difference.
C. Synchronize the Certkiller -WS201 clock with the Certkiller -DC21 clock within a
6-minute difference.
D. Synchronize the Certkiller -WS201 clock with the Certkiller -DC21 clock within a
59-minute difference.
Answer: B
Explanation: Clocks between a client computer and the domain controller should be
synchronized within a 5-minutes difference to ensure that Kerberos authentication is
successful. The difference between the clocks of Certkiller -WS201 and
Certkiller -DC21 is known as time skew. Kerberos policies define the maximum
allowable time skew. If this time skew is greater than the value specified in the
Maximum tolerance for computer clock synchronization Kerberos policy, then Kerberos
will treat the synchronization request as a threat (possibly a replay attack) and then deny
access. This Maximum tolerance for computer clock synchronization is set to five
minutes by default.
Incorrect answers:
A: A 1-minute time difference would be too short a period since the default setting is a
5-minute difference that is allowable.
C: A 6-minute time difference would be too long.
D: If the time difference is more than 30 minutes then Kerberos Authentication will not
occur. A 59- minute difference is far too long and poses an unnecessary security risk as
well.
QUESTION 3:
You work as a network security 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 server named Certkiller -DC21 functions as a domain controller. Authentication
Actualtest.org – The Power of Knowing
on the Certkiller .com network is performed by Kerberos and the default Kerberos
policy values are used throughout Certkiller .com. A User named Clive Wilson makes
use of a client computer named Certkiller -WS201. Clive Wilson contacted the
Certkiller .com helpdesk to report that he is unable to access domain resources from
Certkiller -WS201.
You received instruction to ensure that Clive Wilson is able to access domain
resources. To this end you need to troubleshoot Clive Wilson’s problem. You start
with troubleshooting the authentication process on Certkiller -WS201. Then you
notice that the clock on Certkiller -WS201 is running slow and affecting the
Kerberos authentication process.
What should you do to enable Clive Wilson to access domain resources?
A. Synchronize the Certkiller -WS201 clock with the Certkiller -DC21 clock within a
1-minute difference by adjusting the Certkiller -WS201 computer clock.
B. Synchronize the Certkiller -WS201 clock with the Certkiller -DC21 clock within a
1-minute difference by adjusting the “Maximum tolerance for computer clock
synchronization” Kerberos policy.
C. Synchronize the Certkiller -WS201 clock with the Certkiller -DC21 clock within a
5-minute difference by adjusting the Certkiller -WS201 computer clock.
D. Synchronize the Certkiller -WS201 clock with the Certkiller -DC21 clock within a
5-minute difference by adjusting the “Maximum tolerance for computer clock
synchronization” Kerberos policy.
E. Synchronize the Certkiller -WS201 clock with the Certkiller -DC21 clock within a
31-minute difference by adjusting the “Maximum tolerance for computer clock
synchronization” Kerberos policy.
Answer: D
Explanation: Clocks between a client computer and the domain controller should be
synchronized within a 5-minutes difference to ensure that Kerberos authentication is
successful. The difference between the clocks of Certkiller -WS201 and
Certkiller -DC21 is known as time skew. Kerberos policies define the maximum
allowable time skew. If this time skew is greater than the value specified in the
Maximum tolerance for computer clock synchronization Kerberos policy, then Kerberos
will treat the synchronization request as a threat (possibly a replay attack) and then deny
access. This Maximum tolerance for computer clock synchronization is set to five
minutes by default.
Incorrect answers:
A: A 1-minute time difference would be too short a period since the default setting is a
5-minute difference that is allowable. Besides this would be futile since the time
difference should be modified using the “Maximum tolerance for computer clock
synchronization” Kerberos policy.
B: A 1-minute time difference would be too short a period since the default setting is a
5-minute difference that is allowable.
C: The time difference suggested in this option is correct except that it will not address
the issue since the difference must be modified using the “Maximum tolerance for
Actualtest.org – The Power of Knowing
computer clock synchronization” Kerberos policy
E: If the time difference is more than 30 minutes then Kerberos Authentication will not
occur at all and Clive Wilson will not be able to access domain resources.
