CAFM Maintenance Management 2 — Questions and Answers
Question 1: Which maintenance metric measures the average time between vehicle failures or breakdowns?
- Mean Time Between Failures (MTBF) (Correct answer)
- Mean Time To Repair (MTTR)
- Vehicle Availability Rate
- Preventive Maintenance Compliance Rate
Correct answer: Mean Time Between Failures (MTBF)
MTBF measures the average operating time between failures, indicating vehicle reliability.
Question 2: A fleet manager notices that brake pads are being replaced more frequently on vehicles driven by certain drivers. What is the BEST corrective action?
- Replace brake pads with higher-quality parts
- Implement driver behavior training and telematics monitoring (Correct answer)
- Increase the preventive maintenance interval for brakes
- Purchase vehicles with regenerative braking systems
Correct answer: Implement driver behavior training and telematics monitoring
Driver behavior such as aggressive braking is a leading cause of premature brake wear, so training and monitoring addresses the root cause.
Question 3: What is the primary purpose of a fleet maintenance information system (FMIS)?
- To schedule driver shifts and route assignments
- To track vehicle maintenance history, costs, and work orders (Correct answer)
- To monitor fuel prices and optimize purchasing
- To manage vehicle insurance claims and documentation
Correct answer: To track vehicle maintenance history, costs, and work orders
An FMIS centralizes maintenance records, work orders, and costs to support data-driven fleet management decisions.
Question 4: When evaluating an outsourced maintenance contract, which factor is MOST critical to include in the service level agreement (SLA)?
- The vendor's number of service bays
- Vehicle downtime guarantees and turnaround times (Correct answer)
- The vendor's employee count
- Proximity of vendor to fleet headquarters
Correct answer: Vehicle downtime guarantees and turnaround times
Downtime guarantees and turnaround time commitments directly protect fleet operational availability.
Question 5: Which oil analysis parameter is MOST useful for detecting early signs of engine coolant contamination?
- Total Base Number (TBN)
- Viscosity index
- Sodium and potassium levels (Correct answer)
- Iron particle count
Correct answer: Sodium and potassium levels
Elevated sodium and potassium in oil analysis are telltale indicators of coolant ingestion into the engine oil.
Question 6: A fleet manager is calculating the total cost of ownership (TCO) for a vehicle. Which of the following costs is typically EXCLUDED from TCO calculations?
- Fuel costs
- Driver salary and benefits (Correct answer)
- Depreciation
- Insurance premiums
Correct answer: Driver salary and benefits
Driver labor costs are generally treated as an operational HR cost rather than a vehicle-specific TCO component.
Question 7: What does a high ratio of corrective maintenance to preventive maintenance hours indicate about a fleet's maintenance program?
- The preventive maintenance intervals are too frequent
- The fleet is well-managed with proactive upkeep
- The PM program may be inadequate or not properly followed (Correct answer)
- Vehicles in the fleet are newer and require less attention
Correct answer: The PM program may be inadequate or not properly followed
A high corrective-to-preventive ratio suggests breakdowns are outpacing proactive maintenance, signaling a program deficiency.
