Final answer:
RAID level 0+1, or RAID 10, combines performance from RAID 0 and redundancy from RAID 1. RAID 0 stripes data for higher speed, and RAID 1 mirrors data for added data protection.
Step-by-step explanation:
RAID level 0+1, also known as RAID 10, combines the features of both RAID level 0 and RAID level 1. RAID level 0 provides performance because it stripes data across multiple drives, which can significantly increase speed as multiple disks can read and write data simultaneously. On the other hand, RAID level 1 provides redundancy by mirroring the same data on two separate disks, which ensures that data is not lost if one of the drives fails.
The correct answer to the question 'RAID level 0+1 is used because, RAID level 0 provides ______ whereas RAID level 1 provides ________.' is a) performance, redundancy.
