2. Define RAID. Define RAID levels 0, 1, 3, 5, 6, and 10. Compare and contrast LVM with RAID. When is one better than the other?
3. What is the /sys filesystem on your CentOS systems? What is its purpose?
BONUS. Write a good question and answer that you think should be on the upcoming exam. It can cover anything covered until Monday Feb 15. This is a bonus because if you are fortunate, the question (or something similar) will be on the exam. I will collect and publish the suggested questions (not answers) on the course website.
