第3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.
