Understanding RAID Concepts and Levels

What is the primary purpose of RAID in office networks?

• To increase the number of computers in the network

• To provide fault tolerance and data redundancy

• To reduce the cost of storage

• To improve internet speed

Which RAID level involves striping without redundancy, resulting in faster read and write speeds?

• RAID 1

• RAID 5

• RAID 0

• RAID 10

How does RAID 1 ensure data redundancy?

• By striping data across multiple drives

• By using a parity block

• By mirroring data on all drives

• By using SSDs instead of magnetic drives

What is the advantage of using RAID 5 over RAID 0?

• RAID 5 is cheaper to implement

• RAID 5 provides data redundancy with parity

• RAID 5 has faster read speeds

• RAID 5 uses fewer drives

Which RAID level combines the features of both RAID 0 and RAID 1?

• RAID 5

• RAID 10

• RAID 2

• RAID 3

What does the term "hot swappable" mean in the context of RAID?

• Drives can be swapped only when the system is powered off

• Drives can be swapped while the system is running

• Drives cannot be swapped at all

• Drives can be swapped only during system maintenance

Why might RAID be preferred over storing files on individual computer hard drives in an office network?

• RAID is more expensive, which is better for business

• RAID provides fault tolerance and centralized data management

• Individual hard drives are faster

• RAID requires less technical knowledge

What is the role of a parity block in RAID 5?

• To mirror data across all drives

• To provide a backup of the entire system

• To reconstruct data if a drive fails

• To increase the speed of data access

Which RAID level would you choose if you need both high speed and data redundancy?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

What is a disadvantage of using RAID 0?

• It is the most expensive RAID level

• It does not provide data redundancy

• It requires more drives than other RAID levels

• It is slower than other RAID levels
