NAFA MAINTENANCE MANAGEMENT EXAM
2026 CORE CAFM-CAFS QUESTIONS &
RATIONALES BUNDLE
This comprehensive practice exam bundle covers the core
competencies of the NAFA Maintenance Management module,
including preventive maintenance policies, shop operations,
inventory control, and asset optimization. Each question features
an clear, italicized answer key paired with a bold, high-utility
diagnostic rationale to ensure deep comprehension of complex
fleet management principles. It serves as the ultimate study
companion and test-preparation resource for professionals
aiming to pass their CAFM or CAFS certification.
1. Which of the following is considered a primary
asset management lifecycle phase?
A) Procurement
B) Disposal
C) Operations and Maintenance
D) All of the above
Answer: D) All of the above
Rationale: The asset management lifecycle
comprehensively includes all stages from initial
planning and procurement, through ongoing
operations and maintenance, up to final
disposal.
,2. What is the primary goal of a preventive
maintenance (PM) program?
A) To repair assets after they fail
B) To maximize the trade-in value of vehicles
C) To prevent failure before it occurs by
performing regular servicing
D) To minimize the number of technicians on
staff
Answer: C) To prevent failure before it occurs
by performing regular servicing
Rationale: Preventive maintenance is scheduled
proactively to reduce the likelihood of
unexpected equipment failures and extend
asset life.
3. Which metric measures the average time
elapsed between unlockable failures of a
repairable asset?
A) MTTR (Mean Time to Repair)
B) MTBF (Mean Time Between Failures)
C) OEE (Overall Equipment Effectiveness)
D) KPI (Key Performance Indicator)
Answer: B) Mean Time Between Failures (MTBF)
Rationale: MTBF is a standard statistical metric
used to track the reliability of an asset by
, calculating the average operating time between
breakdowns.
4. What type of maintenance is triggered based on
actual asset condition data rather than calendar
time?
A) Corrective maintenance
B) Predictive maintenance
C) Reactive maintenance
D) Deferred maintenance
Answer: B) Predictive maintenance
Rationale: Predictive maintenance relies on
real-time condition monitoring tools (like oil
analysis or vibration monitoring) to schedule
service right before a failure occurs.
5. In fleet management, what does the acronym
"CMMS" stand for?
A) Computerized Maintenance Management
System
B) Core Manufacturing Maintenance Strategy
C) Corporate Managed Motor System
D) Centralized Material Management Software
Answer: A) Computerized Maintenance
Management System
Rationale: A CMMS is a software platform that
, centralizes maintenance data, tracks work
orders, monitors inventory, and schedules PM
tasks.
6. Which oil analysis result is a primary indicator
of internal engine coolant leakage?
A) High silicon levels
B) Presence of sodium and potassium
C) Increased soot content
D) High copper concentrations
Answer: B) Presence of sodium and potassium
Rationale: Sodium and potassium are common
chemical additives found in engine
antifreeze/coolant, signaling an internal leak
when found in engine oil.
7. What is the term for maintenance tasks that are
postponed due to lack of budget, parts, or labor?
A) Emergency maintenance
B) Preventative maintenance
C) Deferred maintenance
D) Predictive maintenance
Answer: C) Deferred maintenance
Rationale: Deferred maintenance refers
explicitly to backlogged repair or servicing
