If a storage device is flagged as having a potential problem, which term is used to describe its status?

A storage device that is flagged as having a potential problem is described as having "degraded storage." This term indicates that the device is still operational but is functioning below its optimal performance level, suggesting that there may be issues that could lead to a total failure if not addressed. The status of "degraded" serves as a warning to system administrators to monitor the device closely or take corrective action, as it implies that the reliability of the device is compromised.

In contrast, the other terms do not accurately represent the status of a device with potential problems. "Failed" indicates that the device is no longer operational, whereas "unknown" suggests that the system has no information about the device's status. "Active" typically means that the device is functioning properly, which does not apply to a device flagged with potential issues. Thus, "degraded storage" is the correct term to characterize a device at risk of failure while still being operational.
