[Q1]Current Situation: There are three domain controllers in your network, all running Windows 2000 Server. You are using the Active Directory services for which replication is configured for keeping the domain controllers synchronized among themselves. You use Windows backup program for performing backup of all user and system data. One of the domain controllers crashes, and it takes you three days to find out that the problem is due to a virus in the master boot record. Here is what you have to do:
Required Result: Repair the master boot record and fix the startup problem in the server. Restore the user data on the server.
Optional Desired Results:
Restore the System State data so that the server gets the original configuration.
Update the Active Directory data to make it in sync with the other domain controllers.
Proposed Solution: Remove the virus in the master boot record using the AVBoot disk or any third-party anti-virus software. Use the emergency repair process to restore system startup files. Restore the server data from most current backup set using the network backup server.
What results are produced from the proposed solution?
A. The proposed solution produces the required result only.
B. The proposed solution produces the required results and only one of the optional results.
C. The proposed solution produces the required results and both of the optional results.
D. The proposed solution does not produce the required result.
ANSWER:
A: The proposed solution produces the required result only. The required result is produced because you will be able to remove the virus in the master boot record. The emergency repair process can fix the server startup problem. You will also be able to restore the user data on the server. The system state cannot be restored because there is no mention of backing up the system state, only the user data.
B, C, and D are incorrect, because the first of the optional results is not produced because the System State data cannot be restored by the proposed solution. You may recall that the System State data can be restored on a local computer only and the question states that you are performing restore from the network backup server. The second of the desired results is not produced because the Active Directory data is contained in the System State data that is not being restored.
[Q2]You currently have users that are members of the Database Users Organizational Unit (OU). You use a Group Policy linked to the OU to ensure that all users have the Microsoft FoxPro database package installed on their PCs as well as other applications. You have been asked to replace FoxPro with Access 2000. Users should no longer be allowed to use FoxPro. Which of the following would be the most efficient way of doing this?
A. Modify each user's logon script to delete FoxPro and install Access 2000.
B. Edit the Group Policy and click on the "Uninstall this application when it falls out of the scope of management" option. Unlink the Group Policy from the Database Users OU. Create a new Group Policy that installs Access 2000 and link this to the Database Users OU.
C. Edit the Group Policy, select the upgrades tab for FoxPro under Software Installation. Add Access 2000 as the package that will upgrade FoxPro and click on "Required Upgrade for existing Packages."
D. Make Access 2000 available on a network share and ask each user to remove FoxPro and install Access 2000.
ANSWER:
C: C is the most efficient method because it involves the least amount of administrative effort and it ensures that Access 2000 replaces FoxPro. The upgrades feature of software deployment can be used not only to upgrade software to later versions but also to replace one product with another one.
A is incorrect, because although it may work it is not the most efficient. There will be more administrative effort in modifying each user's logon script. B is incorrect, because the current Group Policy also deploys other applications. Unlinking this Group Policy may interfere with this. D is incorrect. Although it may be less effort for the administrator, it does not guarantee that Access 2000 will replace every user's installation of FoxPro.
[Q3]You wish to use the Distributed File System on your network. You have selected one of the computers running Windows 2000 Server operating system that is also being used as a file server and installed a stand-alone DFS root on this volume. However, when you clicked on the Action menu to create DFS links, you notice that the replication Policy Option is not available as shown in the following screen: Which of the following is the best explanation for this?
A. Active Directory does not support DFS Links
B. DNS does not support DFS Links
C. You are not running Active Directory or DNS on your network
D. Windows 2000 Servere does not support DFS Links
ANSWER:
C: Of the answers available, only the absence of Active Directory Services and DNS would cause the Replication Policy to be unavailable as indicated in the illustration. Replication Policy are available only on domain-based DFS roots which would require Active Directory and DNS to be running.
[Q4]You are working as a systems engineer for a large software company. You are setting up a machine for use in your company. This machine will be used to store large amounts of data for a computer-aided design (CAD) system, so you need to create a large drive (30GB is preferred). The machine is configured as follows:
Processor 400MHz Pentium III
Disks 8GB SCSI (system and boot partitions)
10GB SCSI (data)
10GB SCSI (data)
10GB SCSI (data)
CD-ROM 24X
Memory 256Mb
Backup 20GB tape
All of the disks are free space except for the first one containing the system and boot partitions. What is the easiest way to achieve a 30GB logical drive?
A. RAID 5 volume
B. Simple volume
C. Mirrored volume
D. Spanned volume
ANSWER:
D: Spanned volume. A spanned volume can use space from different disk drives to form one large logical drive.
A is incorrect, because a RAID 5 volume results in only 20GB being available if the three 10GB disks are used. B is incorrect, because a simple volume results in only 10GB in the specified configuration. C is incorrect, because a mirrored volume results in only 10GB in the specified configuration.
[Q5]An employee has left your department to work with another department within your company, and a new employee has replaced him. You need to give the new employee access to all the files and folders owned by the departed employee. Which method is the best way to grant ownership of the files owned by the departed employee to the new employee so she can work with them as her own?
A. Give the new employee Full Control access to all folders owned by the old employee so she can work with them no matter who owns them.
B. Rename the old account.
C. Change the owner of all the files and folders from the old employee to the new employee through the Properties window for each object.
ANSWER:
B: In the real world, this is certainly the simplest way to meet your objective.
A is incorrect, because the old employee may not have had Full Control access to some of the folders where he had documents that he owned. Giving the new employee Full Control might give her additional permissions that she does not need. C is incorrect, because there is no way to directly change the owner of a file in Windows.
[Q6]Current Situation: The network in your office has nearly 140 desktops and seven servers, all running the Windows 2000 operating system. There are two large servers running SQL server and both have very large database files. Another server hosts the user home directories. Your boss has purchased another server that will be used as a backup server. He has asked you to use the Windows Backup program. Here is what you have to accomplish:
Required Result: Plan a backup and restore strategy for the network servers. The databases and user data in their home directories must be available in crisis situations.
Desired Optional Results:
There should not be any affect on network performance during the working hours due to running backup jobs.
The cost of media must remain as low as possible.
Proposed Solution: Use Windows Backup program to backup large databases and user data directories. Perform a full backup on each Friday and an incremental backup from Monday to Friday.
What results are produced from the proposed solution.?
A. The proposed solution produces the required result only.
B. The proposed solution produces the required results and only one of the optional results.
C. The proposed solution produces the required results and both of the optional results.
D. The proposed solution does not produce the required result.
ANSWER:
B: The proposed solution produces the required results and only one of the optional results. The required result is produced because the databases and the user home directories are backed up. The data will be available in crisis situations. The second of the optional results is produced because using incremental backup from Monday to Thursday and a full backup on Friday will keep the media costs low and will still be able to provide complete data.
A, C, and D are incorrect, because the first of the optional results is not produced because when backup jobs for the large databases and user home directories are running, it will definitely affect the network performance. You must schedule the backups to run after hours to avoid this problem.
[Q7]You are the network administrator in your office network. The network is growing at a fast pace, and you wish to delegate the backup and restore responsibilities to one of the users who you understand has good knowledge of Windows 2000 Servers. How will you ensure that this user is capable of performing these jobs well, but this user is not allowed to shut down any server without your intervention?
A. Give Full Control permissions to the user on the files that are to be backed up
B. Make the user a member of Server Operators group
C. Make the user a member of Backup Operators Group
D. Add the user to Domain Administrators group
ANSWER:
C: Make the user a member of Backup Operators group. A member of Backup Operators group has sufficient rights to perform backup and restore jobs while bypassing the NTFS security on any files and folders. This privilege does not allow the user to shut down any server in the network.
A is incorrect, because assigning permissions on individual files and folders is a tedious job and is not the desired way of accomplishing the job. Also, it is a security risk to allow the backup operator full control over the files that are backed up. B is incorrect, because this gives the user rights to shut down the servers. D is incorrect, because the domain administrator privileges do not need to be given to the user only for backup and restore jobs.
[Q8]You have just installed a USB device and are having trouble with it. When you look in the Device Manager to investigate, you see the yellow exclamation mark indicating an error or conflict. You suspect a conflicting resource but have no record of which resources are taken by which devices. No inventory was completed of your machine. Of the following options, what is the best way to configure the new device?
A. Remove the device, reboot the machine, add the device, and reboot again, letting Windows 2000 Server detect the device.
B. Disable Plug and Play in Device Manager and manually configure the new device.
C. Disable Plug and Play in the system BIOS and manually configure the new device, and then let Plug and Play configure the remaining, available resources.
D. Take the device back to the manufacturer because it is malfunctioning.
ANSWER:
C: By disabling Plug and Play in the System BIOS, you prevent the device from being incorrectly detected during startup. Windows 2000 Server is designed to make hardware configuration a snap-as long as all your devices support Plug and Play. Unfortunately, in the real world, there are still legacy devices that are Non-Plug and Play, so it is important to note that sometimes it may be necessary to disable Plug and Play in the system BIOS to prevent the device from being detected incorrectly.
A is incorrect, because Windows 2000 Server will still use Plug and Play to detect the device incorrectly. B is incorrect, because Device Manager is not where you disable Plug and Play. D is incorrect, because there is a chance that your new device is malfunctioning, but it is more likely that there is a resource conflict.
[Q9]There are four Windows 2000 Server domain controllers on the network in your office. You are using Windows 2000 network services such as Active Directory, DNS, DHCP, and WINS. The four servers use the File Replication System to keep the Active Directory data in synchronization with each other. You are smart enough to backup the System State data locally on each of the domain controllers. One of the domain controllers fails , and it takes you three days to fix the problem. After restoring the system configuration from the most current backup set, you wish to restore the Active Directory data. Which of the following methods can you use to restore the Active Directory data so that it is updated automatically from other domain controllers?
A. Perform an authoritative restore and run Ntdsutil
B. Perform a non-authoritative restore and run Ntdsutil
C. Perform a non-authoritative restore and wait
D. Run Ntdsutil and wait
ANSWER:
C: Perform a non-authoritative restore and wait. When you want the Active Directory data on a restored domain controller to get synchronized with other domain controllers on the network, you need to perform a non-authoritative restore. File replication services will ensure that this data gets updated automatically.
A is incorrect, because the authoritative restore and Ntdsutil will work to replicate Active Directory data from this server to other domain controllers. B is incorrect, because there is no need to run the Ntdsutil after performing a non-authoritative restore. D is incorrect, because Ntdsutil is run after an authoritative restore to replicate data to other domain controllers.
[Q10]You have a centralized backup server on the network. This server is configured to backup data from 15 other servers on the network. All servers are running Windows 2000 Server operating system. The backup jobs are configured to run in Full mode on Fridays and in Incremental mode from Monday to Friday. On Tuesday afternoon there is an emergency, and you are told to take a backup immediately. Which of the backup types will you select so that the regular scheduled backup jobs are not affected and the process takes the least time?
A. Copy backup
B. Normal backup
C. Incremental backup
D. Differential backup
ANSWER:
D: Differential backup. The best option to perform an unscheduled backup in case of an emergency is to use the differential backup type. This backup gives you complete data in conjunction with the last full backup and any intermediate incremental backups. The differential backup type does not affect the regular backup jobs because it does not clear any archive bits (markers) from the files.
A and B are incorrect, because these backup types will consume significant time. C is incorrect, because this backup type will clear the archive bits that affects regular backup jobs.
