    RAID 5 will restore a failed drive in its array by using

    • A recovery boot CD

    • Defragmenting

    • Distributed parity data

    • NT Backup

    • Mirroring

    Correct Answer
    A. Distributed parity data
    Explanation
    Parity data is special error-correction data that prevents unrecoverable data loss when a drive in the array fails. It bears a mathematical XOR relationship to the data being protected, and allows the RAID to reconstruct missing data by performing an XOR operation on the surviving data. The result of the operation is the missing data. RAID 5 stripes this parity data across the array to provide a good balance of performance and safety, making it the most popular RAID configuration today.

    Rate this question:

  • 44. 

    In a modern hard drive, the number of sectors on the innermost track is _______ the number of sectors on the outermost track.

    • Greater than

    • Less than

    • Equal to

    Correct Answer
    A. Less than
    Explanation
    Early hard drives used simple radial "pie slices" as sector divisions. Thus, every track on the platter would contain the same number of sectors. To increase efficiency, modern hard drives now record data such that tracks near the outer edge of the platter contain more sectors than the innermost tracks. This scheme is called "zoned bit recording" or "ZBR".

    With ZBR, the platter is not sliced radially. Instead, it is concentrically divided into groups of contiguous tracks called "zones". The tracks within a particular zone have the same number of sectors. As these zones radiate outward, the sector counts increase.

    Rate this question:

  • 45. 

    LBA stands for ___________.

    Correct Answer
    Logical Block Addressing
    Explanation
    LBA stands for Logical Block Addressing. This is a method used in computer storage devices to address individual blocks of data. Instead of using the traditional cylinder-head-sector (CHS) addressing scheme, LBA provides a simpler and more efficient way to access data on a disk. Each block of data is assigned a unique logical block address, allowing the operating system to easily locate and retrieve the required information. LBA is widely used in modern storage technologies such as hard disk drives and solid-state drives.
