QUESTION 2
A server has three disks of 80GB each and must manage a database with 4 million records of 30KB each. The best configuration for this server, with the criteria being performance, configurability and flexibility, is:
A. Use just LVM
B. Use RAID1 over LVM
C. Use LVM over RAID5
D. Use LVM over RAID1
E. Use RAID5 over LVM
Answer: C
Explanation/Reference:
RAID1 would not be performance enhancing (Mirroring), as would the default LVM (linear). So use a RAID5 for redundancy and performance and use LVM for added configurability and flexibility
A striped LVM only would work too, I guess, if you need no redundancy at all.
