Question 26: If a system has 4 data disk then How many disks are required if RAID level 2 is implemented
Select one:
a. 6
b. Log 2(4)+1
c. 4
d. 5
Ans: Log 2(4)+1 , the formulae to calculate no of disk is log 2(n) + 1. However, RAID level 2 is outdated but just to know this questions is here.
Question 27: If a system has 4 data disk then How many disks are required if RAID level 6 is implemented
Select one:
a. 4
b. 5
c. Log 2(4)+1
d. 6
Ans: 6
Question 28: Which of the following is TRUE for asynchronous replication techniques
Select one:
a. Asynchronous replication is used when remote site is at large distance from source Correct
b. Asynchronous replication can provide zero data loss
c. None of the given choices are
d. Asynchronous replication may have performance implication on application
Ans: The correct answer is: Asynchronous replication is used when remote site is at large distance from souce
Question 29: Which of the following is an advantage of asynchronous replication when compared with synchronous?
Select one:
a. Asynchronous replication can work at the block level
b. The remote storage array can be a different model
c. Asynchronous replication replicates less data than synchronous
d. The remote site can be further away
Ans: The correct answer is: The remote site can be further away
Question 30: which of the statement is true for multi level cell
Select one:
a. Stores two bit of data per cell
b. It stores 2 bit per cell by applying different level of voltage
c. All the choices are correct Correct
d. it has Lower PE cycle 10000
Ans: The correct answer is: All the choices are correct
