Question 900
On a service ticket for Bluefin Logistics, the team observes: A mirrored NAS reports one disk failed while files remain available. The supporting record states that the array state is degraded and the replacement disk must match controller support and capacity. The desired outcome is to restore RAID redundancy without wiping the surviving volume. Only approved service procedures and compatible replacement components may be used. Which post-repair signal best detects regression or repeat exposure?
- Monitor firmware resets and missing boot entries
- Monitor pickup count and repeated jam positions
- Monitor BIOS lane-sharing changes and unsupported replacement drive orders
- Monitor rebuild progress and additional SMART failures
Explanation
Correct Answer
D:
Monitor rebuild progress and additional SMART failures. It tracks recurrence of the specific failure mechanism over time. The relevant observation is that the array state is degraded and the replacement disk must match controller support and capacity. The support goal is to restore RAID redundancy without wiping the surviving volume; this monitor action specifically addresses degraded raid after a failed member without confusing a different subsystem.
Incorrect Answers
A:
Monitor firmware resets and missing boot entries. This action is appropriate for uefi boot order after a second drive, normally when a computer reports no bootable operating system after a new secondary drive was added. Here the observed facts require degraded raid after a failed member instead.
B:
