A customer is experiencing a performance issue with a specific VNX file system. Analyzer showed that the utilization of several RAID Groups was in the red. The problematic file system, however, was mapped only to one of those RAID Groups, while other RAID Groups served file systems without known issues. How would you explain utilization metric to this customer?

A.
Utilization is a calculated number that determines how busy an object is, and it is likely to be too high rather than too low.

B.
Utilization is a derived number that carries very little weight, and it is likely to be too low rather than too high.

C.
Utilization is a calculated number that is used only for the internal spinning disk write/read adjustment algorithms, and it is always definitive.

D.
Utilization is a metric showing the ratio between capacity and spinning speed. When high, it is an indicator that a particular disk should be replaced.
