RAID Recovery Course - RAID Introduction Test
RAID is short for
Reliable Array of Inexpensive Disks
Redundant Array of Inexpensive Disks
Redundant Array of Independent Disks
Reliable Array of Independent Disks
Which of the following is the JBOD parameter set?
start offset, block size
start offset, disk order
block size, disk order
Is it obligatory to use identical disks to create a RAID?
Check those which can be RAID parameters
Where is RAID metadata stored?
at the end of the member disk
at the beginning of the member disk
anywhere, depending on the implementation specifics
Is there a RAID meeting all the RAID criteria simultaneously?
On which disk or disks is RAID metadata stored?
on all member disks
on the first member disk
on one particular member disk
Speed improvement is achieved due to the fact that:
data on a RAID is not fragmented
each member disk in RAID is faster than a regular hard drive
two data blocks on two disks can be read in one operation
What is start offset?
offset at which RAID user data starts
offset at which RAID metadata starts
Check those which are not the criteria applied for RAIDs
