Questions
1. You administer a Windows 2000 domain. A junior network administrator named Nancy is to deploy Windows 2000 Professional on 90 computers in your domain. Nancy will manage those computers after the deployment.
Which of the following actions should you perform?
a. Nothing needs to be done; any domain user can perform an installation and manage the client computers by default.
b. Use the Delegation of Control wizard to grant Nancy permissions on the Computers container in the Active Directory Users and Computers (ADUC) console.
c. Grant Nancy the Add workstations to domain right in the local GPO on each computer to be added.
d. Grant Nancy the Add workstations to domain right in a GPO linked to the domain.
e. Grant Nancy the Add workstations to domain right in a GPO linked to the Domain Controllers OU.
f. Put Nancy's domain account into the local Administrators group on each computer to be added.
2. On a Windows 2000 Professional computer, you are configuring a dial-up connection to an RRAS server that is located at your company's headquarters. The RRAS server can support two 33.6-Kbps connections. The RRAS server also supports the Point-to-Point Protocol (PPP) and the PPP Multilink Protocol (MP). You have a choice of the following modems that you can install on your local computer: one 56-Kbps modem, one 33.6-Kbps modem, three 28.8-Kbps modems, and four 14.4-Kbps modems. The 56-Kbps modem and the 33.6-Kbps modem will not function together in the same computer. You want to connect to the RRAS server with the greatest connection bandwidth possible.
Which of the following modem configurations should you use?
a. one 33.6-Kbps modem
b. four 14.4-Kbps modems configured with multilink
c. one 56-Kbps modem and one 14.4-Kbps modem configured with multilink
d. two 28.8-Kbps modems configured with multilink
3. You attach a new print device to a Windows 2000 Server computer on your company's network. You install the printer for the print device and enable sharing. Users report that they cannot find the printer among multiple servers and shared resources on the network. To make it easier for the users to find the printer, you decide to publish it in Active Directory. You open the Sharing tab of the Properties sheet for the printer, but there is no option to publish the printer in Active Directory.
Which of the following is the most likely reason that you cannot publish the printer in Active Directory?
a. The print server is not a member of a Windows 2000 domain.
b. You are logged on to the local Administrator account on the print server.
c. Your domain user account does not have administrative privileges on the print server.
d. You are logged on to a local user account that does not have administrative privileges on the print server.
4. You are responsible for technical support for Windows 2000 users on your company's network. A user calls you and reports that her Windows 2000 Professional computer unexpectedly stops booting normally and displays a message stating that an error occurred while loading the operating system. You verify that the physical disk is properly recognized by the system and appears to be functional. You must enable the user to boot normally as soon as possible and minimize possible data loss.
Which of the following should you do?
a. Repair the master boot record and system partition boot sector.
b. Copy the Ntldr file from a Windows 2000 CD.
c. Copy the Ntdetect.com file from a Windows 2000 CD.
d. Create a new Boot.ini file on another computer and copy it to the failed computer.
5. On a dual-CPU Windows 2000 computer, you install a Win32 application that was custom designed to run on multiple CPUs. Later, you notice that, when this application is running, the computer's performance becomes very slow. Your monitoring indicates that CPU1 is busy almost 100 percent of its time, whereas CPU2 spends only about 15 percent of its time processing requests. You want to improve the performance of this computer.
Which of the following should you do?
a. Change the CPU affinity for the application.
b. Run the application on CPU1.
c. Run the application on CPU2.
d. Reduce the application's base priority.
Answers:
1) Choice b is correct. To meet the requirements as stated in the scenario, you should first right-click the Computers container in ADUC and select Delegate Control, which will invoke the Delegation of Control wizard. Then, follow the wizard prompts and grant Nancy's domain user account the Create Computer objects permission. Granting Nancy this permission will allow her to add as many computers to the domain as necessary. She will become the owner of those computer objects.
The Add workstations to domain right is granted to Authenticated Users in the Default Domain Controllers Policy Group Policy object (GPO), by default. Therefore, in a Windows 2000 domain, any member of the Users or Domain Users group can add new computers to the domain, by default. This right works only on domain controllers because computer accounts are created only on domain controllers. Therefore, any authenticated domain user can add up to 10 workstations to the domain in which the user's account resides. The Domain Admins group becomes the owner of those computer accounts. This does not meet the requirements of the scenario because Nancy needs to add 90 computers to the domain, and she should be able to manage those computers after the deployment. To add a computer to a domain, a user must log on to a local user account that is a member of the local Administrators group on that computer. This condition is met in this scenario because Nancy will install Windows 2000 Professional herself; therefore, she has full control of all local accounts. However, her domain user account does not have to belong to the local Administrators group on those computers. To add a computer to the domain, Nancy should log on to the local Administrator account and, when prompted, she will specify her domain user account name and password. If necessary, she can add her domain user account to the local Administrators group on the new computers after she has added those computers to the domain.Reference:W2KSOH, Contents, "Security," "Concepts," "Using Security," "Delegating Administrative Control."

2) Choice d is correct. The maximum bandwidth of a connection between a client computer and an RRAS server is determined by the slower modem speed of the two computers. Furthermore, when modems are multilinked on one computer, all linked modems will run at the speed of the slowest modem. In this scenario, installing and using two 28.8-Kbps modems configured with multilink would result in the greatest connection bandwidth. The multilink feature combines multiple physical links into a single aggregate link to increase connection bandwidth. You can enable multilink for a dial-up connection on the Options tab of the Properties sheet for the connection. Multilink options appear only if your computer is equipped with more than one modem. For the multilink feature to work, both your local computer and the remote access server must have multilink enabled.
The maximum speed available during a multilink session is equal to the sum of the individual modem speeds. Thus, two 28.8-Kbps modems will provide a maximum speed of 57.6 Kbps. Using a single 33.6-Kbps modem will provide a maximum connection speed of 33.6 Kbps. Using a 56-Kbps modem and a 14.4-Kbps modem will provide a maximum connection speed of 28.8 Kbps because the 56-Kbps modem will be limited to 14.4 Kbps, the speed of the slower modem. Although four 14.4-Kbps modems with multilink enabled would also provide a maximum speed of 57.6 Kbps (14.4 x 4), the RRAS server has only two modems available for the connection. The two 14.4-Kbps modems could connect at a combined speed of 28.8 Kbps. Note that the actual speed of a given session is dependent on the telephone line quality and is negotiated at the time of connection.

3) Choice a is correct. To facilitate locating shared resources on a Windows 2000 network, you can publish the resources in Active Directory. Users then will be able to find the resources by browsing Active Directory in Windows Explorer. Two conditions must be met before you can publish a printer that is installed on a Windows 2000 Server computer: the computer must be a member of a Windows 2000 domain, and the printer must be shared. If you add a printer and share it by using the Add Printer wizard on a member server, then the printer will be published automatically. To publish a shared printer manually, you should enable List in the Directory on the Sharing tab in the printer's Properties sheet. In this scenario, this option does not appear on the Sharing tab because the print server is not a member of a Windows 2000 domain.
Once the print server is joined to a Windows 2000 domain, the List in the Directory option will appear on the Sharing tab in the printer's Properties sheet, regardless of the user account that you are logged on to. If you then logged on to the local Administrator account on the print server, then you would be able to publish the printer. If you logged on to a local or domain user account that does not have sufficient authority to share and publish printers, then these options would appear disabled on the Sharing tab.

4) Choice a is correct. Error messages that are returned at startup and that indicate a failure to load or find an operating system or error messages that detect an invalid disk configuration are often caused by corruption of the master boot record (MBR) or system partition boot sector on the hard disk. To address such problems, you should boot from a Windows 2000 CD, select the option to repair an installation and then start the Recovery Console. The Recovery Console is a text-mode recovery and troubleshooting tool that allows you to gain access to the file system on hard disks of a computer on which Windows 2000 fails to start. Among the available commands in the Recovery Console, you can carry out the FixMBR and Fixboot commands in an attempt to repair a corrupted MBR and the system partition boot sector, respectively.
Ntldr, Ntdetect.com and Boot.ini are the files that must be located on the system partition and are necessary for the system to boot properly. If the system failed to boot because the Ntldr file had been corrupted or was missing, then you would receive a message explicitly stating that Ntldr was missing. If the system failed to boot because the Ntdetect.com file was missing, then you would receive the "Ntdetect failed" message. If the system failed to boot because the Boot.ini file was missing, then you would receive a message stating that Boot.ini was missing. The system would then attempt to proceed based on the assumption that the boot partition was the same as the system partition and that the operating system was installed in the default folder, such as C:\Winnt. If this assumption proved wrong, then you would receive a message stating that the \system32\hal.dll file could not be found. To replace the missing or corrupted Ntldr, Ntdetect.com or Boot.ini file, you could use the Recovery Console to copy the appropriate file from a Windows 2000 CD or from a floppy disk.

5) Choice a is correct. The results of your monitoring indicate that CPU1 is overloaded, whereas CPU2 is almost idle. It appears that that the new application is configured to run only on CPU1. Because this application is specifically designed to run on computers with multiple CPUs, or SMP computers, you should reconfigure its affinity in order to enable the application to use both CPUs. An affinity mask defines the CPU or CPUs that an application should or should not use. Generally, CPU affinity can be permanently specified in an application's code or it can be specified by using Task Manager at the application's run time. An application that is specifically designed to run on SMP computers may be programmed to provide a GUI-based option to configure a CPU affinity mask. Reducing the application's base priority would not prevent the application from using processor time; the application would still be assigned to the same processor.
