Objective: Maintaining the Active Directory Environment
Sub-Objective: Configure backup and recovery


Single Answer, Multiple Choice


You are the systems administrator for your company. You install Windows Server 2008 on a computer and configure it as a file server, named FileSrv. The FileSrv computer contains four hard disks that are configured as basic disks. You want to configure Redundant Array of Independent Disks (RAID) 0+1 on FileSrv for performance and fault tolerance of data.


To achieve this, you need to convert the basic disks in FileSrv to dynamic disks. Which command should you use?



  1. Diskpart.exe
  2. Chkdsk.exe
  3. Fsutil.exe
  4. Fdisk.exe





  1. Diskpart.exe


You should use the Diskpart.exe command. RAID is commonly implemented for both performance and fault tolerance. There are various RAID levels that you can choose from to provide fault tolerance, performance or both. RAID 0 uses disk striping and offers the fastest read and write performance, but it does not offer any fault tolerance. If a single disk in a RAID 0 array is lost, all data is lost and will need to be recovered from backup. RAID 1 uses disk mirroring with two disks. This configuration produces slow writes, but relatively quick reads, and it provides a means to maintain high data availability on servers because a single disk can be lost without any loss of data. RAID 0+1 combines RAID 0 and RAID 1 and offers the performance of RAID 0 and the fault tolerance of RAID 1. To be able to configure RAID 0+1, you must have dynamic disks. If your disks are configured as basic disks, you can convert them to dynamic disks with the Diskpart.exe utility. The Diskpart utility enables a superset of the actions that are supported by the Disk Management snap-in. You can use the Diskpart convert dynamic command to change a basic disk into a dynamic disk.


The Chkdsk.exe command cannot be used to convert a basic disk to dynamic disk. Chkdsk.exe is a command-line utility that creates and displays a status report for a disk based on the file system. The Chkdsk utility also lists and corrects errors on the disk.


You should not use the Fsutil.exe command. Fsutil.exe is a command-line utility that can be used to perform many FAT and NTFS file system related tasks, such as managing reparse points, managing sparse files, dismounting a volume or extending a volume. The Fsutil utility cannot be used to convert a basic disk to dynamic disk.


The Fdisk.exe command cannot be used to convert a basic disk to dynamic disk. Fdisk.exe is a command-line utility that can be used to partition a hard disk. You can use the Fdisk utility to create, change, delete or display current partitions on the hard disk and to assign a drive letter to each allocated space on the hard disk.
