[Q31]Current Situation: You have an NT4.0 domain that needs to be upgraded to Windows 2000. However, your management insists that there must be a fallback plan to allow a return to an NT4.0 based domain should there be a problem with using the Windows 2000 domain after the upgrade.
Required Result: Ensure that it is possible to revert back to using the NT4.0 domain controllers.
Optional Desired Result: There should be no loss of account changes (e.g. new users, password changes) in the event of reverting back to NT4.0 domain controllers.
Proposed Solution: In the NT4.0 domain, synchronize a BDC with the PDC. Remove the BDC from the network and keep it for possible future use as a fallback. Complete the upgrade of the PDC and all other BDCs to Windows 2000. In the event of a problem after the upgrade remove the Windows 2000 domain controllers, reconnect the BDC to the network that was set aside and promote it to a PDC.
Which of the following results will the proposed solution produce?
A. The proposed solution produces the required result and produces the optional result.
B. The proposed solution does not produce the required result but produces the optional result.
C. The proposed solution produces the required result but not the optional result.
D. The proposed solution does not produce the required result or the optional result.
ANSWER:
C: By setting aside a BDC as a fallback it is possible to revert back to the NT4.0 domain by promoting it to a PDC, thereby meeting the required result. However, any account maintenance carried out on the Windows 2000 domain controllers will be lost if the BDC is restored to use, so the optional desired result is not met. A strategy to minimize the amount of the potential loss would be to periodically reconnect the BDC to the network and synchronize it with the PDC emulator in the Windows 2000 domain and then remove it again. This strategy would only be possible whilst the Windows 2000 domain is in mixed mode operation.
[Q32]Current Situation: To meet the demand for new workstations you have decided to use RIS on your network but are concerned about the security aspects.
Required Result: Setup several servers as RIS Servers.
Optional Desired Results: Only pre-authorized workstations should be allowed to download images; workstations should download their images from a specific RIS server.
Proposed Solution: Install RIS on Windows 2000 domain controllers. Configure a separate partition on separate disks on each server for the RIS images and ensure that the required network services for RIS are running. Authorize the RIS Servers in Active Directory. For each workstation pre-configure computer accounts in Active Directory and specify the name of the remote installation server.
A. The proposed solution produces the required result and produces both of the optional results.
B. The proposed solution produces the required result and produces only one of the optional results.
C. The proposed solution produces the required result and produces none of the optional results.
D. The proposed solution doesn't produce the required result.
ANSWER:
B: The RIS servers will be set up and configured to run. Pre-configuring or pre-staging the computer accounts and assigning them to specific RIS servers will ensure that only the specified RIS server will service the request. However, the RIS server will still service requests from other workstations that have not been configured because the "Do not respond to unknown clients" option has not been set. Therefore the required result and only one of the optional results are met.
A, C, and D are incorrect, because the solution produces the required result and one of the optional results.
[Q33]An e-commerce company has two autonomous divisions that trade under different names. Both divisions rely extensively on Internet sales and their domain names (gandalf.lotr and frodo.lotr) are well known. The company wishes to upgrade to Windows 2000, but it is essential that the two domain names are maintained. Although the divisions work autonomously the company wants to easily share resources and IT administrative functions between the two divisions. The IT staff in the gandalf.lotr domain ran the Active Directory Installation Wizard and selected the option to install a domain controller in a new forest. Which of the following options should the IT staff in the other division use to install their first domain controller?
A. As an additional domain controller in the gandalf.lotr domain
B. As a domain controller for a new child domain frodo.gandalf.lotr
C. As a domain controller in a new domain tree called frodo.lotr in the existing forest
D. As a domain controller in a new domain tree frodo.lotr in a new forest.
ANSWER:
C: The domain controller should be added in its own domain (frodo.lotr) and not as a child domain, therefore a new domain tree is required. To easily share resources and administrative functions with the other domain the new domain tree should be part of the existing forest. This means that the benefits of two-way transitive trusts can be exploited to access resources between domains.
A and B are incorrect, because they do not maintain the domain name for frodo.lotr. D is incorrect, because installing in a new forest will mean that sharing resources between the two domains will be more complicated requiring the use of manually created trusts.
[Q34]Current Situation: Your company has a number of PCs running UNIX that need to have Windows 2000 Server installed. Each PC has one disk that has one partition that contains UNIX. No other partitions are defined, but there is 2Gigabytes of spare disk space.
Required Result: You want to successfully install Windows 2000 Server.
Optional Desired Result: You have been asked to preserve the existing UNIX partition.
Proposed Solution: Boot the PC into UNIX and run winnt32 off the Windows 2000 CD and select a new partition for the Windows 2000 installation.
A. The proposed solution produces the required result and produces the optional result.
B. The proposed solution does not produce the required result and the optional result is met only because of the failure of the required result.
C. The proposed solution produces the required result but not the optional result.
D. The proposed solution does not produce the required result or the optional result.
ANSWER:
B: It is not possible to install Windows 2000 while booted into UNIX. Therefore the Windows 2000 installation will fail. Technicallym this means the optional result is met because the UNIX installation will remain unaltered. To install Windows 2000 Server and to be able to dual boot with UNIX a third-party boot manager should be used.
[Q35]You have a Windows 2000 Server designated as an application server. Several programs run on this server. You have noticed that one of the applications runs very slow. You wish to increase the execution speed of this application by setting a higher priority. What will be the affect of changing the priority of this application on other applications?
A. The other applications will not be affected.
B. The performance of other applications will also increase.
C. The performance of other applications will be decreased.
D. The other applications will stop responding.
ANSWER:
C: The performance of other applications will be decreased. When you set the priority of a particular application to a higher value, the performance of other applications gets affected negatively.
A is incorrect because changing the priority of one application affects the performance of other applications. B is incorrect because the performance of other applications will not be increased by setting -the priority higher for one application. D is incorrect because the other applications will not stop responding but may become slow.
[Q36]One of the Windows 2000 Server computers in your network has been infected with a virus and has corrupted the Master Boot Record. The system is not starting up due to this problem. Which of the following methods can you use to remove the virus?
A. Use fixmbr command from the Recovery Console
B. Use Emergency Repair Process to fix the Master Boot Record
C. Use AVBoot disk to remove the virus
D. Use fixboot command from the Recovery Console
ANSWER:
C: Use the AVBoot disk. Windows 2000 includes an anti-virus program that is located in the \Valueadd\3rdparty\CA_antiv folder on the setup CD-ROM. This program can be used to scan and remove viruses from the Master Boot Record. You can create an anti-virus bootable floppy disk using the makedisk.exe command located in this folder.
A is incorrect, because Microsoft recommends that you use the Anitvirus Disk first to repair the Master Boot Record when a virus has corrupted it. B is incorrect, because the Emergency Repair process cannot be used to remove a virus from the Master Boot Record. D is incorrect, because the fixboot command in the Recovery Console can fix only a corrupted boot sector and will not be helpful if a virus has corrupted the master boot record.
[Q37]It has come to your attention that someone is trying to gain access to secure data by logging on using the Administrator Account. How can you prevent a security breach of this sort? (Check all that apply.)
A. Change the password for the Administrator Account.
B. Delete the Administrator Account.
C. Set the Account Lockout Policy to Lock out accounts after one incorrect login.
D. Set up auditing to find out who is trying to gain access using the Administrator Account.
ANSWER:
A, D: By changing the password to your administrator account often, you will prevent intruders from guessing what it might be. Setting up Auditing will help you find out whether your intruder might be someone from within your company rather than an outside intruder.
B is incorrect, because the Administrator Account cannot be deleted. It can, however, be renamed, which is also a good idea. Answer C is incorrect because you cannot lock out the Administrator account.
[Q38]You have two hard disks on your Windows 2000 Server computer. You have decided to keep another paging file on the second disk in order to improve system performance. You have installed recovery console on this computer for emergency purposes. The system is also running complete Microsoft Office 2000 suite. Which of the following will give you best performance without affecting the installed system recovery options?
A. Move the complete paging file to second disk
B. Keep a larger paging file on first disk and a smaller paging file on the second disk
C. Keep a smaller paging file on the first disk and a larger paging file on the second disk
D. None of the above
ANSWER:
C: Keep a smaller paging file on the first disk and a larger paging file on the second disk. This is the best option to optimize the paging file since the system also has recovery console installed.
[Q39]The backup operator of your network is telling you that some of the backup jobs could not be completed the previous night due to a network problem. He is unable to find out information on the files that were not backed up or that were partially backed up. What can you suggest to him so that he is able to know the exact status of the backup jobs?
A. Check the creation dates on backup tapes
B. Check the backup log files
C. Click the Verify option in Backup Wizard options
D. Perform a restore to verify
ANSWER:
B: Check the backup log files. The best way to know the status of backup jobs is to check the backup log files. This gives you correct information on how the job ran and which files and folders were backed up.
A is incorrect, because checking creation dates on backup tapes is a tedious process and will not give accurate information. C is incorrect, because the Verify option is used before starting the backup job and is of no use once the job has finished. D is incorrect, because it is an absolutely an undesired method of verifying the status of backup.
[Q40]Current Situation: A small company has asked for your help in determining the best way to upgrade their existing NT4.0 network to Windows 2000. The company has decided that it wants to upgrade to Windows 2000 as quickly as possible to take advantage of some of the new security features. The company currently has one master account domain for user accounts. There are two resource domains that contain servers that contain computer accounts, databases, and e-mail servers.
Required Result: Upgrade the company to Windows 2000.
Optional Desired Results: Minimize the amount of effort required to complete the upgrade by the company's IT staff; minimize the cost of upgrading.
Proposed Solution: Restructure the network into a single Windows 2000 domain model. To achieve this you recommend: installing a single new Windows 2000 domain in parallel with the existing domains, copying all user and computer accounts to the new domain, upgrading all computers to Windows 2000, and ensuring that everything works before decommissioning the Windows NT4.0 network
Which of the following results will the proposed solution produce?
A. The proposed solution produces the required result and produces both of the optional results.
B. The proposed solution produces the required result and produces only one of the optional results.
C. The proposed solution produces the required result and produces none of the optional results.
D. The proposed solution doesn't produce the required result.
ANSWER:
C: The solution will provide the company with a Windows 2000 based network. Reducing the number of domains during an upgrade can be beneficial. But it does take considerable planning which would involve the IT staff in a lot of work. Creating a new parallel Windows 2000 domain is a good way of ensuring that the current environment is not disrupted and allows for a period of parallel running;but this would mean spending more money on new servers. In this situation it was required to minimize IT staff effort and expenditure; maintaining the existing domain structure would be cheaper and require much less effort. Therefore neither of the optional results was met.
A, B, and D are incorrect, because the proposed solution produces only the required result but not any of the optional desired results.
