第8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.


正确答案:BCG
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.

  • A、Create a simple volume on disk and then expand it to the other two disks.
  • B、Create a mirrored volume that uses two of the disks.
  • C、Create a RAID-5 volume that uses all three disks.
  • D、Create a striped volume that uses all three disks.
