What is the primary purpose of SMART's firmware-level monitoring?

• A. To monitor disk health and predict failures
• B. To monitor network traffic
• C. To manage CPU scheduling
• D. To optimize power consumption

Answer: (A)

SMART's firmware-level monitoring is focused on the health and reliability of the storage device itself. It continuously collects data from the drive’s firmware—things like how many sectors have been remapped, current pending sectors, error rates, temperature, and spin-up behavior—and analyzes trends against thresholds. The goal is to provide early warnings of potential failures so you can back up data or replace the drive before a failure leads to data loss or downtime. This kind of monitoring is specific to the disk’s condition and isn’t about network traffic, CPU scheduling, or power optimization, which are outside the storage health domain.
