In which two scenarios would you recommend using RAID level 5 as an option for database
storage?(Choose two.)
A.
For a database with lower recovery (MTTR) overhead
B.
For a database in which the applications primarily perform read operations and predominantly
sequential I/O is performed
C.
For a database in which performance is the primary goal of the database because applications
are demanding in terms of I/O operations
D.
For a database in which the database size grows rapidly, the cost of storage is critical and data
accessibility is more important than performance
A is wrong. disk performance not too much related to MTTR
B is wrong.
C is right. performance
D is right. cheaper compared with RAID 1+0
So C.D. are correct
I think B is more appropriate because RAID5 is good for read operations
A is wrong
B is correct, as RAID 5 is good for read operations
C is not correct, as RAID 5 is not so good for write operations (lasts two times as much)
D is correct
So B.D. are correct
