SECTION 1: MAINTENANCE STRATEGIES (Questions 1–15)
Question 1
Which of the following is a primary maintenance strategy?
A) Lubricant analysis
B) Oil sampling
C) Predictive maintenance
D) Root cause analysis
Correct Answer: C
Rationale: Predictive maintenance is a core maintenance strategy, while lubricant analysis and oil
sampling are tools and techniques used within such strategies. Root cause analysis is a problemsolving
methodology rather than a primary maintenance strategy.
Question 2
What is the main goal of preventive maintenance?
A) To wait for equipment to fail before taking action
,B) To reduce energy consumption
C) To address potential issues before failure occurs
D) To increase lubricant viscosity
Correct Answer: C
Rationale: Preventive maintenance aims to resolve potential problems before equipment failure occurs,
thereby reducing unplanned downtime and extending asset life.
Question 3
Which maintenance strategy waits for a machine to fail before any action is taken?
A) Predictive maintenance
B) Proactive maintenance
C) Runtofailure maintenance
D) Reliabilitycentered maintenance
Correct Answer: C
Rationale: Runtofailure (also known as breakdown maintenance) is a strategy where equipment is
allowed to operate until it fails, at which point repairs are made. This is typically used for noncritical
equipment where failure does not have significant consequences.
Question 4
ReliabilityCentered Maintenance (RCM) primarily focuses on:
,A) Scheduling routine maintenance only
B) Identifying and addressing failure modes
C) Using only synthetic lubricants
D) Running machines continuously
Correct Answer: B
Rationale: RCM is a systematic approach that identifies critical assets, analyzes potential failure modes,
and determines appropriate maintenance tasks to prevent or mitigate those failures. It focuses on
preserving system functions rather than just maintaining equipment.
Question 5
In Total Productive Maintenance (TPM), which pillar involves operators performing basic maintenance
tasks?
A) Planned maintenance
B) Autonomous maintenance
C) Condition monitoring
D) Lubricant blending
Correct Answer: B
Rationale: Autonomous maintenance empowers operators to take responsibility for basic maintenance
activities on the equipment they operate, including cleaning, inspection, and lubrication tasks.
Question 6
, What is the primary objective of a conditionbased maintenance (CBM) program?
A) To perform maintenance at fixed calendar intervals
B) To monitor equipment condition and perform maintenance only when needed
C) To replace all lubricants annually
D) To eliminate all maintenance activities
Correct Answer: B
Rationale: CBM uses realtime monitoring of equipment condition (such as oil analysis, vibration analysis,
and thermography) to determine when maintenance is actually required, optimizing maintenance
resources and minimizing unnecessary interventions.
Question 7
Which of the following is NOT a benefit of implementing a proactive maintenance strategy?
A) Extended equipment life
B) Reduced unplanned downtime
C) Increased catastrophic failures
D) Lower overall maintenance costs
Correct Answer: C
Rationale: Proactive maintenance aims to prevent failures before they occur. Increased catastrophic
failures are a characteristic of runtofailure strategies, not proactive maintenance approaches.
