Actual exam question for CompTIA's 220-1201 exam
Question #: 253
Topic #: 1
A technician checks a RAID 5 array and sees a S.M.A.R.T. alert on one disk, but the array still shows healthy. What should the technician do next?

Suggested Answer: D Vote an answer

A S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) alert indicates a physical hardware-level issue with the drive, suggesting it is likely to fail in the near future. While the RAID
5 array is currently still healthy (operating in a degraded state with one potential failure that hasn't fully manifested yet), the predictive failure alert means the drive must be replaced as a proactive measure. The data on the drive can be rebuilt onto a new, healthy drive using the parity and data from the remaining disks in the array.
