The two primary methods of proactive maintenance are preventive maintenance and _____________ maintenance.

• A. Predictive
• B. Corrective
• C. Reactive
• D. Routine

Answer: (A)

Proactive maintenance aims to prevent failures before they happen. Preventive maintenance uses scheduled tasks to reduce wear, but predictive maintenance takes a step further by analyzing condition-monitoring data to forecast when a component will fail and schedule service just in time. This data-driven timing is why predictive maintenance is the correct fill for completing the phrase. The other options describe actions that occur after a failure or are routine checks not tied to forecasting and preventing failures.
