RAID Technology

What does RAID stand for?

• Redundant Array of Independent Disks
• Random Access of Independent Data
• Redundant Array of Indexed Data
• Random Array of Independent Drives

Which RAID level is known for disk striping?

• RAID 0
• RAID 1
• RAID 5
• RAID 10

What is the primary benefit of RAID 0?

• Data redundancy
• Increased read/write speed
• Hot-swappable drives
• Parity check

What happens if one drive fails in RAID 0?

• Data is lost on that drive only
• Data is lost on all drives
• Data is automatically backed up
• Drive rebuilds itself

Which RAID level is known as disk mirroring?

• RAID 0
• RAID 1
• RAID 5
• RAID 10

What does RAID 1 prioritize?

• Speed
• Redundancy
• Storage capacity
• Compression

How does RAID 1 handle a failed drive?

• Data is lost
• Rebuilds the data on a new drive
• Creates parity bits
• No action is taken

Which RAID level requires a minimum of three drives?

• RAID 0
• RAID 1
• RAID 5
• RAID 10

RAID 5 combines which of the following features?

• Disk striping and parity
• Disk mirroring and striping
• Hot-swappable and mirroring
• Striping and data compression

In RAID 5, what is the purpose of parity bits?

• Increase speed
• Provide redundancy
• Compress data
• Backup entire data
