MANAGEMENT EXAM
Question 1
Which key performance indicator (KPI) is most directly associated with the effectiveness of a fleet’s
preventive maintenance schedule?
A) Average vehicle age
B) PM compliance rate
C) Cost per mile
D) Technician utilization rate
CORRECT ANSWER: B – PM compliance rate measures the percentage of scheduled preventive
maintenance tasks completed on time, directly reflecting schedule effectiveness.
Rationale: Average vehicle age (A) influences costs but not PM effectiveness. Cost per mile (C) is a
broad financial metric. Technician utilization (D) relates to shop productivity, not PM adherence.
Question 2
What is the primary benefit of implementing a dynamic maintenance scheduling system based on real-
time vehicle telematics?
A) Reduced initial vehicle purchase price
B) Elimination of all unplanned breakdowns
C) Condition-based maintenance instead of fixed intervals
D) Lower fuel taxes
CORRECT ANSWER: C – Telematics enable condition-based maintenance (e.g., engine hours, fault
codes), optimizing intervals.
,Rationale: Purchase price (A) is unaffected. Breakdowns (B) cannot be fully eliminated. Fuel taxes (D)
are unrelated.
Question 3
According to NAFA guidelines, which document should be completed before any maintenance work
order is closed?
A) Driver vehicle inspection report
B) Parts requisition form
C) Repair order with technician labor hours and parts used
D) Warranty claim form
CORRECT ANSWER: C – The repair order must document all work, parts, and labor for accurate costing
and history.
Rationale: Driver reports (A) are pre-trip. Parts requisition (B) is internal. Warranty claim (D) is
separate and not always applicable.
Question 4
A fleet manager notices rising oil analysis reports showing high silicon levels. What is the most likely
cause?
A) Fuel dilution
B) Coolant leakage
C) Dirt ingress through air intake system
D) Excessive idling
CORRECT ANSWER: C – Silicon indicates airborne dirt, often from a faulty air filter or intake leak.
Rationale: Fuel dilution (A) lowers viscosity. Coolant leakage (B) shows sodium/potassium. Idling (D)
increases soot.
Question 5
,Which maintenance strategy aims to replace components at predetermined intervals regardless of
condition?
A) Predictive maintenance
B) Reliability-centered maintenance (RCM)
C) Time-based maintenance (TBM)
D) Reactive maintenance
CORRECT ANSWER: C – TBM uses fixed calendar or usage intervals (e.g., replace timing belt every 60,000
miles).
Rationale: Predictive (A) uses condition monitoring. RCM (B) combines multiple strategies. Reactive
(D) repairs after failure.
Question 6
What is the ideal inventory turn ratio for a fleet’s fast-moving spare parts (e.g., oil filters, brake pads)?
A) 0.5 – 1.0
B) 1.5 – 3.0
C) 4.0 – 6.0
D) 8.0 – 12.0
CORRECT ANSWER: C – A turnover of 4–6 indicates parts are used and restocked efficiently without
excessive stock.
Rationale: Lower than 4 (A, B) suggests overstocking. Higher than 6 (D) risks stockouts for common
items.
Question 7
Under federal regulations (FMCSA), which maintenance record must be retained for at least one year
after a vehicle is sold?
A) Driver’s daily log
B) Annual inspection report
, C) Roadside inspection report
D) Repair order for brake work
CORRECT ANSWER: B – Annual inspection reports (DOT inspection) must be kept for 14 months or one
year after sale, whichever is longer.
Rationale: Driver logs (A) are separate. Roadside reports (C) kept for 12 months. Brake repair orders
(D) should be kept but not specifically regulated for same duration.
Question 8
A technician finds metal shavings in the differential fluid. The recommended next step is:
A) Change fluid and ignore
B) Perform magnetic particle inspection of gears
C) Send oil sample for spectroscopy analysis
D) Replace the entire differential
CORRECT ANSWER: C – Spectroscopy identifies metal type (e.g., iron vs. copper) to pinpoint failing
component.
Rationale: Changing fluid (A) masks problem. Magnetic inspection (B) requires disassembly.
Replacement (D) is premature without diagnosis.
Question 9
Which metric best measures the efficiency of a fleet maintenance shop?
A) Mean time to repair (MTTR)
B) Vehicle availability
C) Total cost of ownership (TCO)
D) Fuel economy
