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?
The correct answer is D. Replace the failing drive. 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…

Explanation
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.
