Objective 1.3 Optimize Server Disk Performance 14 - 27 4. Oksana is looking at a report generated by the disk defragmenter of her system. Her system contains two volumes. The first volume is 100 GB and is mirrored on a second 100 GB disk. The second volume is 400 GB and uses RAID-5 over five 100 GB disks. The report that Oksana is examining was an analysis performed on the second volume rather than the first. Oksana is puzzled because there seems to be several sections on the second volume that are colored green. Green in a defragmenter analysis represents unmovable files. Oksana is puzzled because she believed that the only files that were unmovable for the disk defragmenter are located on the system or boot volumes. What is the cause of the unmovable files listed on the defragmenter analysis of the second volume? (Select all that apply.) A. Oksana has mistakenly analyzed the first volume, which contains the boot and system files. B. The page file has been located on the second volume. C. Oksana has stored encrypted files on the second volume. D. Oksana has stored compressed files on the second volume. E. The NTFS change journal, stored on all NTFS volumes, is an unmovable file. 5. Oksana has scheduled a command-line disk defragmentation job to take place at 2 A.M. every Sunday on all Windows Server 2003 systems at her site. This represents a perfect time to perform such a task because the amount of activity on any of the servers at this time is minimal. Checking through the logs on a Monday morning, Oksana finds that the Sunday morning defragmentation did not occur on one of the volumes on one of the Windows Server 2003 servers. Oksana logs onto the server from a remote desktop connection and checks the Disk Defragmenter in the Computer Management Console. Oksana decides to wait until the end of business that day and try to run the defragmen- tation process again on this volume. At 6:30 P.M. she logs on from the remote desktop again and attempts to initiate a defragmentation of the problematic volume. The pro- cess fails again. What could be causing the failure, and which of the following steps should Oksana take to defragment this volume? A. The volume is failing to defragment because it is close to capacity. A volume must have at least 15 percent of space free for the defragmentation process to begin. B. The volume has been marked as dirty. Oksana needs to run Chkdsk from the com- mand line before she can defragment the volume successfully. C. Oksana must take the volume offline manually to perform the defragmentation. Once this is done, the disk will defragment normally. D. Oksana needs to dismount the disk hosting the volume to perform a defragmen- tation. Once this is done, the disk will defragment normally.

Objective 1.3 Optimize Server Disk Performance 14 - 29 Objective 1.3 Answers 1. Correct Answers: A, B, C, and E A. Correct: Disk mirroring provides no read/write benefit but does provide fault tolerance. B. Correct: RAID-5 must generate parity information while writing to the disks, something that disk striping (RAID-0) does not need to do. RAID-5 parity genera- tion provides some latency, making this method slower than disk striping. C. Correct: Disk spanning has similar performance to a simple volume whereas disk striping is the quickest method of reading and writing to a volume. D. Incorrect: Disk spanning has similar performance to a simple volume, disk strip- ing offers the best read/write performance. E. Correct: In disk striping, data can be written to or read from multiple disks mak- ing up the volume at one time. In a simple volume, only one disk can be written to or read simultaneously.

Incorrect: Rooslan achieved all the goals of the first team. For the second team, he achieved the first and second goals. By choosing to mirror, rather than stripe, the third volume, he did not create a volume of 240 GB with the fastest read/write speed. The volume would have been 120 GB and would not have performed sig- nificantly better than a simple volume. Rooslan achieved one goal of the third team. He achieved the first goal, but by using RAID-5 instead of striping, he failed to achieve the second. The second volume would have been 360 GB rather than 480 GB as specified, the equivalent of one drive lost in storing parity information. B. Incorrect: Rooslan achieved all the goals of the first team. For the second team, he achieved the first and second goals. By choosing to mirror, rather than stripe, the third volume, he did not create a volume of 240 GB with the fastest read/write speed. The volume would have been 120 GB and would not have performed sig- nificantly better than a simple volume. Rooslan achieved one goal of the third team.

Correct: Disk 1 is a mirrored volume of a volume on Disk 0. No data will be lost if this disk fails. B. Incorrect: If disk 0 fails, data will be lost as any data that is not on the Datastore volume, such as the boot volume, is not protected. C. Correct: Disk 2 is part of a RAID-5 array, hence if disk 2 fails, parity information can be used to regenerate the data. D. Correct: Datastore is a mirrored volume compared to Archive on RAID-5, and RAID-5 is faster than RAID-1 (mirroring). E. Incorrect: Datastore is a mirrored volume compared to Archive on RAID-5. RAID-5 is faster than RAID-1 (mirroring). F. Incorrect: Disk 3 is also part of the RAID-5 array; therefore, if Disk 3 fails, data will not be lost. 4. Correct Answers: B and E A. Incorrect: The question states clearly that it is the second volume, so Oksana is not mistaken. B. Correct: Page files are unmovable files and therefore are reported in green by the disk defragmenter analyzer. Similarly, the NTFS change journal, on NTFS volumes, is also represented by the unmovable green. C. Incorrect: Encrypted and compressed files are not unmovable. D. Incorrect: Encrypted and compressed files are not unmovable. E. Correct: Page files are unmovable files and therefore are reported in green by the disk defragmenter analyzer. Similarly, the NTFS change journal, on NTFS volumes, is also represented by the unmovable green.

Incorrect: If a disk has less than 15 percent of space left, the defragmentation process will finish, but the disk will not be completely defragmented. B. Correct: Disk defragmentation will fail only when a disk has errors. If a disk has errors, it is classified as “dirty” by the operating system. The only way to change this state is to perform a Chkdsk operation on the disk and complete all required repairs. C. Incorrect: Disks cannot be defragmented if they are taken offline. D. Incorrect: Volumes cannot be defragmented if they are taken offline. 6. Correct Answers: B, C, D, and E A. Incorrect: This figure is below the 10% threshold, so Windows will not recom- mend a defragmentation. B. Correct: This figure is above the 10% threshold, so Windows will recommend a defragmentation. C. Correct: This figure is above the 10% threshold, so Windows will recommend a defragmentation. D. Correct: This figure is above the 10% threshold, so Windows will recommend a defragmentation. E. Correct: This figure is above the 10% threshold, so Windows will recommend a defragmentation. Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Objective 1.4 Install and Configure Server Hardware Devices 14 - 33 Objective 1.4 Install and Configure Server Hardware Devices A signed driver is one that has a digital certificate attached from Microsoft that guaran- tees that the driver has been tested on a wide variety of configurations and has been deemed reliable. Windows Server 2003 can be configured to look for this particular digital certificate and refuse to install drivers that have not met with Microsoft’s approval. An administrator may not wish to use only Microsoft-approved device drivers all the time. Administrators can override any signing settings by manually setting this option in the System Properties. The options include Block, Warn, and Ignore. Block disallows the installation of unsigned drivers, Warn allows the installation but produces a mes- sage that must be approved notifying the administrator that the user is about to install unsigned drivers, and Ignore produces no warning and simply installs the drives regardless of whether they have been digitally signed. The resources that a hardware device uses can be configured in the Device Manager by selecting the device and, from the Action menu, selecting Properties. Newly installed hardware can sometimes conflict with other hardware on the system and these con- flicts can best be resolved by adjusting resources such as I/O range and IRQ.

Oksana has recently replaced Rooslan as the systems administrator of six Windows Server 2003 systems. These six servers are stand-alone systems and not members of any domain. Several weeks into her tenure, Oksana receives the go-ahead to buy a Digital Audio Tape (DAT) backup drive for each of the Windows Server 2003 systems. At a prescheduled time she brings the servers down and installs the new hardware. When all the servers have been brought up, Oksana logs on to each and is confronted by the Add New Hardware Wizard. She begins the process of installing the software for the new hardware but finds that the process fails because the driver cannot be installed. Oksana then investigates the driver signing setting in the System Properties. The driver signing option is set to Block with the other options dimmed. Although the drivers have not been digitally signed by Microsoft, Oksana has decided that she wants to use them and that they will pose no problems to the stability of the servers that she administers. Which of the following actions can Oksana take to allow the installation of unsigned drivers on all six of these Windows Server 2003 systems? (Select all that apply.) A. Oksana should reconfigure the domain GPO and set the Unsigned Driver Installa- tion Behavior policy to Warn But Allow Installation. B. Oksana should reconfigure the local GPO and set the Unsigned Driver Installation Behavior policy to Warn But Allow Installation. C. Oksana should check the Administrator Option / Make This Action The System Default check box in the Driver Signing Options dialog box, accessible from the System Properties. This will enable her to switch the option from Block to Warn. D. Oksana should reconfigure the GPO assigned to the site that the servers are set up in and set the Unsigned Driver Installation Behavior policy to Warn But Allow Installation. E. Oksana should reconfigure the GPO applied to the OU that the servers are mem- bers of and set the Unsigned Driver Installation Behavior policy to Warn But Allow Installation.

You are a systems administrator at a medium-sized organization. You maintain a test lab of five Windows Server 2003 systems that are all members of your organization’s single domain. Because the organization has had trouble in the past with some users with sufficient privileges installing unsigned drivers on the system the default domain GPO has been configured to block the installation of all unsigned drivers on computers that are members of the domain. The domain GPO also blocks access for all users to the System Properties and hides all icons on the desktop. Until recently this was unproblematic; however you have just received a new batch of high-performance net- work cards that you wish to test on your lab servers. These high performance network cards ship with drivers that have not been digitally signed by Microsoft. Because you cannot access the System Properties you cannot override the default domain GPO set- ting that blocks the installation of unsigned drivers. Which of the following methods allows you to override the default domain GPO and change the setting on your lab servers to Warn but not change the overall setting for other computers in your domain? A. Edit the local GPO on each server and set the Unsigned Driver Installation Behav- ior policy to Warn But Allow Installation. B. Edit the GPO applied to the site in which the servers in your lab reside and set the Unsigned Driver Installation Behavior policy to Warn But Allow Installation. C. Create a new organizational unit called Mylab. Move the computer accounts for the Windows Server 2003 systems in to the Mylab OU. Create a GPO that sets the Unsigned Driver Installation Behavior policy to Warn But Allow Installation and apply it to the Mylab OU. D. Edit the Domain GPO and set the Unsigned Driver Installation Behavior policy to Warn But Allow Installation. E. Create a group and put your user account in this group. Create a GPO that sets the Unsigned Driver Installation Behavior policy to Warn But Allow Installation and apply this GPO to the newly created group.
