CSA Facility Operations & Maintenance 2 — Questions and Answers
Question 1: Which maintenance strategy involves replacing components at fixed time intervals regardless of their condition?
- Predictive maintenance
- Corrective maintenance
- Preventive maintenance (Correct answer)
- Condition-based maintenance
Correct answer: Preventive maintenance
Preventive maintenance schedules component replacement at fixed intervals to prevent failures before they occur.
Question 2: What is the primary purpose of a Building Management System (BMS) in a facility?
- Manage employee schedules
- Monitor and control mechanical and electrical systems (Correct answer)
- Track inventory of supplies
- Process work order invoices
Correct answer: Monitor and control mechanical and electrical systems
A BMS centralizes monitoring and control of HVAC, lighting, fire safety, and other building systems.
Question 3: A technician notices vibration in a pump during operation. Which diagnostic tool is best suited to analyze this issue?
- Thermal imaging camera
- Vibration analyzer (Correct answer)
- Multimeter
- Ultrasonic thickness gauge
Correct answer: Vibration analyzer
A vibration analyzer measures frequency and amplitude of vibrations to diagnose mechanical issues in rotating equipment.
Question 4: What does 'Mean Time Between Failures' (MTBF) measure in facility equipment management?
- Average time to repair a failed component
- Average operational time between successive failures (Correct answer)
- Total downtime over a year
- Cost per failure incident
Correct answer: Average operational time between successive failures
MTBF is the average time a system operates between failures, used to estimate equipment reliability.
Question 5: In a data center environment, what is the recommended temperature range per ASHRAE guidelines for equipment intake air?
- 50–60°F (10–15.5°C)
- 59–77°F (15–25°C)
- 64.4–80.6°F (18–27°C) (Correct answer)
- 85–95°F (29–35°C)
Correct answer: 64.4–80.6°F (18–27°C)
ASHRAE A1-class equipment intake air should be maintained between 64.4°F and 80.6°F (18–27°C).
Question 6: Which fire suppression system is most appropriate for a server room to avoid water damage to equipment?
- Wet pipe sprinkler
- Deluge system
- Clean agent (gaseous) suppression (Correct answer)
- Dry pipe sprinkler
Correct answer: Clean agent (gaseous) suppression
Clean agent systems use inert or chemical gases to suppress fires without leaving residue or causing water damage to electronics.
Question 7: What is a 'hot aisle/cold aisle' configuration designed to achieve in a data center?
- Separate high-voltage and low-voltage cabling
- Improve airflow management to reduce cooling costs (Correct answer)
- Provide dedicated power paths to server racks
- Organize racks by server manufacturer
Correct answer: Improve airflow management to reduce cooling costs
Hot aisle/cold aisle layout alternates rack orientations so exhaust air and cool intake air don't mix, improving cooling efficiency.
