NAFA Maintenance Management Exam 109 Practice Questions, Answers &
Rationales 2026
Exam Structure: Each NAFA Maintenance Management module exam contains
approximately 50 multiple-choice questions, with a 90-minute time limit and a
passing score of approximately 75% .
SECTION 1: Preventive vs. Breakdown Maintenance (Questions 1-10)
Question 1
Define preventive maintenance.
A) Repairs performed after a vehicle has broken down
B) Services and/or checks scheduled based on measurable intervals designed to
keep vehicles functioning properly
C) Emergency maintenance called in by drivers
D) Annual inspections required by DOT
Correct Answer: B
Rationale: Preventive maintenance is proactive maintenance performed at
scheduled intervals (mileage or time-based) to prevent failures before they occur
.
,Question 2
Define demand or breakdown maintenance.
A) Regularly scheduled oil changes
B) Inspections required by federal regulations
C) Maintenance performed on an unscheduled basis after a failure has occurred
D) Warranty-covered repairs
Correct Answer: C
Rationale: Demand maintenance is reactive—it occurs when a vehicle breaks
down unexpectedly and requires immediate repair to return to service .
Question 3
What impact does lack of maintenance have on vehicle lifespan?
A) Vehicles will last longer due to fewer repairs
B) The lifespan of vehicles will be reduced, requiring earlier replacement
,C) Only the engine is affected
D) There is no measurable impact
Correct Answer: B
Rationale: Without periodic maintenance, vehicle lifespan decreases significantly.
Costly systems and components fail earlier than expected, forcing premature
replacement .
Question 4
What impact does lack of maintenance have on drivers?
A) Drivers are unaffected
B) Drivers receive bonuses for reporting issues
C) Drivers are greatly inconvenienced, productivity drops, and maintenance
personnel may be blamed
D) Drivers prefer breakdown maintenance
Correct Answer: C
, Rationale: When vehicles break down unexpectedly, drivers lose productive work
time, become frustrated, and often blame the maintenance department for poor
reliability .
Question 5
What impact does lack of maintenance have on the maintenance department's
workload?
A) Workload remains constant and predictable
B) The department requires fewer staff
C) Workload is characterized by extreme peaks and valleys, requiring overtime or
temporary help
D) The department can operate with a smaller parts inventory
Correct Answer: C
Rationale: In reactive maintenance environments, workload is unpredictable.
Peaks occur during breakdown crises, while valleys leave staff idle—an inefficient
and costly operating pattern .
