第1题：
You are the network administrator for Ezonexam. You are installing Windows 2000 Server on a new computer by using the Windows 2000 Server compact disk. The computer has five 18-GB hard disks Dick0, Disk1, Disk2, Disk3, and Disk4. The disks do not have any partitions defined.
You want to use as much space on Disk0 as possible for the partition on which Windows 2000 Server is installed. You want the disk on which you install Windows 2000 Server to be fault tolerant. You also want as much disk space as possible across the other disks to be available for data storage and to be fault tolerant.
What should you do? (Each correct answer presents part of the solution. Choose three)
A. Install Windows 2000 Server on a 4-GB NTFS partition on Disk 0. Configure the five disks as dynamic disks.
B. Install Windows 2000 Server on a 18-GB NTFS partition on Disk 0. Configure the five disks as dynamic disks.
C. Create a RAID-5 volume using Disk2, Disk3, and Disk4.
D. Create a stripped volume using Disk2, Disk3, and Disk4.
E. Create a RAID-5 volume using all disks.
F. Create a stripped volume using all disks.
G. Select the volume on Disk0 and add a mirror using Disk1.
B,C,G 解析：Explanation: RAID-5 volume is where data is written to 3 to 32 physical disks at the same rate, and is interlaced with parity to provide fault tolerance for a single disk failure. Good read performance; good utilization of disk capacity; expensive in terms of processor utilization and write performance as parity must be calculated during write operations.
Only Windows 2000 supports dynamic storage. To support dynamic storage, a single partition is created that includes the entire disk. A disk that you initialize for dynamic storage is a dynamic disk. Dynamic disks are divided into volumes, which can consist of a portion or portions of one or more physical disks. A dynamic disk can contain simple volumes, spanned volumes, striped volumes (RAID-0), mirrored volumes (RAID-1), and striped with parity volumes (RAID-5). You create a dynamic disk by upgrading a basic disk. A Mirrored volume is where two disks contain identical copies of data. The only software RAID supported on the system volume. Good read and write performance; excellent fault tolerance; but costly in terms of disk utilization, because 50 percent of the volume's potential capacity is used for data redundancy.
Incorrect answers:
A: It is not necessary to install Windows 2000 Server on a 4-GB NTFS partition on Disk0. Disk0 consists of 18-GB.
D: Striped volume is where data is written to 2 to 32 physical disks at the same rate. It offers maximum performance and capacity but no fault tolerance.
E: The main disadvantage of a RAID-5 volume is that once a drive fails, system performance suffers until you rebuild the RAID-5 volume. This is because the parity information must be recalculated through memory to reconstruct the missing drive. If more than one drive fails, the RAID-5 volume becomes inaccessible. This does not bode well for fault tolerance as is required in this question.
F: Striped volumes do not provide fault tolerance.

You are the network administrator for TestKing. The network contains a Windows Server 2003 computer named testking1, which hosts a critical business application named Salesapp. Testking1 has one disk that contains a single NTFS volume. Five days ago, the System State of testking1 was backed up, and an Automated System Recovery (ASR) backup was created. No additional backups were performed. Subsequently, many changes were made to the Salesapp data files. You apply an update to the application, which requires you to restart testking1. Windows startup terminates with a Stop error. You restart the computer and boot to a floppy disk. A utility on this disk gives you read-only access to the NTFS file system. You discover that one of the .dll files for the Salesapp application is corrupted. The corrupted file is stored in the C./Windows/System32 folder. You need to restore the corrupted file. You need to avoid losing any changes made to the data files on testking1. What should you do onTestKing1?（）
- A、Perform the ASR restore procedure.
- B、Restart Windows by using the Last Known Good configuration option.
- C、Start the Recovery Console and replace the corrupted .dll file with a copy from the Salesapp CD-ROM.
- D、Reinstall Windows Server 2003. Do not format any volumes.

第8题：
You are the administrator of a SQL Server 2000 computer. You have two new hard disks on which you will create a database named inventory. You want to insert, update, and delete data as quickly as possible.
Which two actions should you take? (Each correct answer presents parts of the solution. Choose two)
A. Configure the hard disks as two mirrored NTFS volumes.
B. Configure the hard disks as one mirrored NTFS volumes.
C. Configure the hard disks as two independent NTFS volumes.
D. Configure the hard disks as one extended NTFS volume.
E. Place inventory_data.mdf on the first volume and inventory_log.ldf on the second volume.
F. Place inventory_data.mdf on the first volume and inventory_data2.ndf and inventory_log.ldf on the second volume.
G. Place inventory_data.mdf and inventory_log.ldf on the same volume.
C,E 解析：Explanation: Placing log files and the data files on different physical disks or independent volumes, and placing the log file of a drive that does not hold the operating system can improve database performance as it allows the frequently written to log file to exist a disk with its own read/write heads and thus less seek time.
Note: A Windows 2000 supports basic disks, in which physical disks are divided into partitions, and dynamic disks, in which disks are divided into volumes that can comprise an entire disk, two or more entire disks, portions of a disk, or portions of up to 32 physical disks.
A NTFS volume is volume that is formatted with the NTFS file system. Physical database design involves mapping the logical design onto physical media to allow for the data to be physically accessed and maintained as quickly as possible by taking advantage of the available hardware and software features. It is important to correctly design the database and to take advantage of hardware and software features early in the development cycle of a database application, because making changes to these components at a later stage it is difficult.
Incorrect Answers:
A: For redundancy and fault protection the log file can be placed on a mirrored volume. It would not be a good idea to put data files on a mirrored volume though. Performance when accessing the data would suffer.
Note: A mirrored volume is a fault-tolerant volume that duplicates data on two physical disks. It provides data redundancy as it copies the data on one volume to another volume on a different disk. When one of the physical disks fails, the data on the failed disk becomes unavailable, but the system can continue to operate by using the mirror disk. In such a set up, the data file and the log file will reside on the same drive. This will not improve database performance.
B: A mirrored volume cannot comprise of one volume only. It must comprise of two volumes on separate physical disks as a mirrored volume is a fault-tolerant volume that duplicates data on two physical disks. When one of the physical disks fails, the data on the failed disk becomes unavailable, but the system can continue to operate by using the mirror disk.
D: Data is written and read sequentially on extended volumes. As a result the data file and the log file will be placed on the same physical disk.
F: In this scenario the data file is separated into a primary data file, that uses the .mdf extension, and a secondary data file, that uses the .ndf extension. However, the secondary data file is placed on the same volume as the log file. This will lead to performance improvements only in cases where data is not read from the secondary data file.
G: Placing the data file and the log file on the same volume will not improve database performance as it will not allow parallel processing.
