Question options:
a. RAID 0
b. RAID 1
c. RAID 5
d. RAID 6
e. RAID 10
Answer:
d. RAID 6
Explanation:
RAID is Redundant Array of Inexpensive/Independent Disks. RAID combines low cost physical hard disk drives in one hard disk drive. RAID is used to achieve data redundancy(data backup but with synchronization) or improved performance or both.
To get what the director requires he would need to use RAID 6. RAID 6 is RAID level optimized to achieve data redundancy but with slow performance.
Answer:
C. Mean
Explanation:
Mean = (∑
)/N
Median = central values when data is sorted
Mode = most repeated value
Standard deviation = 
In standard deviation, formula you may see that deviation is being calculated from the mean (central location). But here we take square of the value before adding all of them.
But if we just take
, it would be equal to zero.
<u>EXAMPLE</u>
Take 4, 9, 5 as data
mean = (4+9+5)/3 = 18/3 = 6
sum of deviations from mean = (4-6)+(9-6)+(5-6) = (-2)+(3)+(-1) = 0
