Which of the following statements are true of striped volumes? (Choose all that apply.)
- A.Striped volumes provide enhanced performance over simple volumes.
- B.Striped volumes provide greater fault tolerance than simple volumes.
- C.You can extend striped volumes after creation.
- D.If a single physical disk in the striped volume fails, all the data in the entire volume is lost.

A. Correct: Striping provides improved performance because each disk drive in the
array has time to seek the location of its next stripe while the other drives are
writing. B. Incorrect: Striped volumes do not contain redundant data and therefore do not provide fault tolerance. C. Incorrect: Striped volumes cannot be extended after creation without destroying the data stored on them in the process. D. Correct: If a single physical disk in the striped volume fails, all the data in the entire volume is lost. |

Which of the following statements best describes the requirements for extending a
volume on a dynamic disk? (Choose all that apply.)
- A.If you want to extend a simple volume, you can use only the available space on the same disk if the volume is to remain simple.
- B.The volume must have a file system (a raw volume) before you can extend a simple or spanned volume.
- C.You can extend a simple or spanned volume if you formatted it by using the FAT or FAT32 file systems.
- D.You can extend a simple volume across additional disks if it is not a system volume or a boot volume.

A. Correct: When extending a simple volume, you can use only the available space
on the same disk. If you extend the volume to another disk, it is no longer simple. B. Incorrect: You can extend a simple or spanned volume, even if it does not have a file system (a raw volume). C. Incorrect: You can extend a volume if you formatted it by using the NTFS file system. You cannot extend volumes by using the FAT or FAT32 file systems. D. Correct: You can extend a simple volume across additional disks if it is not a system volume or a boot volume. |

Which of the following volume types supported by Windows Server 2012 R2 provide
fault tolerance? (Choose all that apply.)
- A.Striped
- B.Spanned
- C.Mirrored
- D.RAID-5
- Answer & Explanation
- Report
Answer : [C, D]
Explanation :
Explanation :
|
A. Incorrect: A striped volume spreads data among multiple disks, but it writes the
data only once. Therefore, it does not provide fault tolerance. B. Incorrect: A spanned volume uses space on multiple drives, but it writes the data only once. Therefore, it does not provide fault tolerance. C. Correct: A mirrored volume writes duplicate copies of all data to two disks, thereby providing fault tolerance. D. Correct: A RAID-5 volume writes data and parity information on multiple disks, thereby providing fault tolerance. |

A JBOD drive array is an alternative to which of the following storage technologies?
- A.SAN
- B.SCSI
- C.RAID
- D.iSCSI
- Answer & Explanation
- Report
Answer : [C]
Explanation :
Explanation :
|
A. Incorrect: A SAN is a separate network dedicated to storage and a JBOD is a drive
array that can be installed on a SAN or on a standard network. B. Incorrect: SCSI is disk interface, not a type of drive array. C. Correct: A JBOD array is an alternative to a RAID array that treats each disk as an independent volume. D. Incorrect: A JBOD array is not an alternative to iSCSI, which is a protocol used for SAN communications. |
