Which statement best describes SMART's predictive capability?

Which statement best describes SMART's predictive capability?

• A. SMART can predict every potential failure.
• B. Some failures can be predicted but not all.
• C. No — some failures are sudden or electrical.
• D. SMART can predict only firmware-related failures.

Answer: (C)

SMART health monitoring looks for signs of wear or degradation on a drive and can give warnings when those indicators trend toward failure. But not every failure leaves a detectable warning. Some failures occur suddenly or due to an electrical issue, leaving no predictive signal for SMART to flag in advance. That limitation is why this statement best describes SMART’s predictive capability: there are failure modes that happen without warning, so SMART cannot predict every issue. The other ideas overstate SMART’s reach or miscast which kinds of failures SMART can forecast.
