  1. Which type of UPS topology provides the highest level of power protection by always running equipment off the inverter?

    Answer: Double-conversion (online) UPS

    Double-conversion UPS always powers the load through the inverter, completely isolating equipment from power anomalies.

  2. A facility administrator needs to track all maintenance activities and asset repair history. Which system is best suited for this?

    Answer: CMMS (Computerized Maintenance Management System)

    A CMMS is specifically designed to manage maintenance work orders, schedules, and asset histories.

  3. What is the function of a PDU (Power Distribution Unit) in a server room?

    Answer: Distribute electrical power from a source to multiple devices

    A PDU distributes electrical power from a single source (like a UPS output) to multiple servers or devices in a rack.

  4. When performing a lockout/tagout (LOTO) procedure, what is the correct sequence for re-energizing equipment after maintenance?

    Answer: Notify affected personnel → remove lockout devices → restore energy

    OSHA LOTO procedures require notifying all affected personnel before removing devices, then restoring energy safely.

  5. What metric does Power Usage Effectiveness (PUE) measure in a data center?

    Answer: Ratio of total facility power to IT equipment power

    PUE = Total Facility Power / IT Equipment Power; a PUE of 1.0 is ideal, meaning all power goes to IT equipment.

  6. Which lighting control strategy offers the greatest energy savings in areas with variable occupancy?

    Answer: Occupancy sensor-based controls

    Occupancy sensors automatically turn lights off when areas are unoccupied, maximizing energy savings in variable-use spaces.

  7. What is the primary risk of operating a diesel generator without periodic load testing?

    Answer: 'Wet stacking' — carbon buildup from running under no-load conditions

    Wet stacking occurs when diesel generators run without sufficient load, causing unburned fuel and carbon deposits to accumulate in exhaust systems.
