QUESTION 25 The parity technique in RAID: O spreads data across mutiple drives (more than one) using the drives in parallel. ensures protection of data with mantaining a full set of duplicate data and using a mathematical construct that allo ws recreation o the missing data O spreads same data on two different disk drives.yielding two copies of the same cata. protects striped data fram disk drive failure without the cost of mirroring QUESTION 26 Which of the following is not included in the FCP Stack implementation? FC-4 Upper Layer Protocol Mapping OFC 3 Sequenc O es Exchanges FC-2 Framing/Flow Control FC- 1 Encode/Decode QUESTION 27 Logical block addressing simplifes addressing by using a linear address to access physical blocks of data using the os to recognize each HDD geometry using a cylinder, head, and sector (CHS) number to reter to specitic locations on the disk using logical blocks mapped to physical sectors on a 2:1 basis. QUESTION 28 The striping technique in RAID spreads same data on two different disk drives,yielding two copies of the data spreads data across mutiple drives (more than one) using the drivesin para lel spreads data across mutiple drives,using the drives in sets of three. ensures protection of data without maintaining a tull set of duplicate data by using a mathematical construct that allows recreation of the missing data

Explanation / Answer

25).b.ensures protection of data without maintaining a full set of duplicate data and using a mathematical construct that allows re-creation of the missing data.

A particular parity function is manipulated for every data block.suppose any failure of drive occurs , the absent blocks were enumerated by offering the fault tolerance.

26). b.FC-3 Sequences /Exchanges

It includes FC-0 also along with FC-1,FC-2 and FC-4 Layers which elucidates meida.

27).a .Linear adress to acess physical blocks of data.  

It is employed to define the position of blocks over a storage utensils like hard disks.

28).b. spreading data across multiple drives (more than one) in order to use the drives in parallel.

Disk striping could advance the manipulations and preserves ever data unit simply in single place and unable to provide data protection whenever disk failure.striping improoves the perfomance and permits the data in less duration for processing.
