A technician is configuring a new web server and must have over 10TB of fault-tolerant storage, while minimizing the number of failure points.
The applications on the server also require the highest performance available.
Which of the following configurations would the technician MOST likely select?

Given the requirement for over 10TB of fault-tolerant storage, the most appropriate RAID configuration that would meet this requirement while minimizing the number of failure points would be RAID 10. RAID 10, also known as RAID 1+0, combines both RAID 0 and RAID 1 to create a fault-tolerant and high-performance storage solution.
RAID 0 configuration is a striped configuration, which means that data is split across multiple drives. However, it provides no redundancy and any single drive failure will result in data loss. This makes RAID 0 a poor choice for a fault-tolerant storage solution.
RAID 1 is a mirroring configuration, which means that data is written identically to two or more drives. This provides redundancy, but reduces the available storage space by 50%. RAID 1 would be a good choice for fault-tolerance, but would not meet the storage requirement of over 10TB.
RAID 5 is a parity-based configuration, which means that data is striped across multiple drives with parity information to allow for the reconstruction of data in case of a single drive failure. However, RAID 5 is not recommended for very large drives as the time required for rebuilding the array after a drive failure may be quite long.
RAID 10 provides both redundancy and performance by striping data across mirrored pairs of drives. This means that if a single drive fails, the other drive in the mirror can take over, providing redundancy. RAID 10 is also a high-performance solution since data can be read and written from multiple drives simultaneously. The use of 6TB drives ensures that the storage requirement of over 10TB is met while the use of 5400rpm drives ensures that the performance requirements are also met.
Therefore, the most appropriate configuration for the given requirements would be RAID 10 with 5400rpm 6TB drives.
