Answers:

1. Fires happen in data centers:
   1. True
   2. False

    

2. What are the costs of data center fires?
   1. The facility’s professional reputation
   2. Data loss
   3. Facility downtime
   4. Economic loss
   5. All of the above

    

3. Fire incidents account for what percentage of data center outages?
   1. 5%
   2. 10%
   3. 21%
   4. 34%

    

4. Cloud computing eliminates the risk from fire.
   1. True
   2. False

    

5. Which data center features present fire suppression challenges?
   1. Open areas
   2. Small parking lots
   3. Hot/cold aisle containment
   4. Redundant systems
   5. Both A and C

    

6. The fire suppression methods least likely to damage electronic equipment are:
   1. Clean agents and water mist
   2. Traditional sprinkler systems and carbon dioxide
   3. A Dalmatian and an old fire hose

    

7. Why is clean agent fire suppression “clean”?
   1. The agents are electrically nonconducting
   2. A special cleanser has been infused into the gas
   3. They leave no residue upon evaporation
   4. Both A and C

    

8. Clean agents can consist of:
   1. Potassium nitrite and monosodium glutamate
   2. Halocarbons, fluorinated ketones, or inert gases
   3. Levothyroxine, adalimumab, and helium

    

9. How does water mist suppress a fire?
   1. Radiant heat blocking and cooling
   2. Reducing the oxygen content only at the seat of the fire
   3. Blows it out
   4. Both A and B

    

10. Which of these statements about inert gases is not true?
    1. Inert gases are naturally present in the air
    2. Inert gases make no known contribution to the depletion of the ozone layer
    3. Inert gases are heavier than air
    4. Inert gas agents suppress fires by reducing oxygen content

     

11. Traditional sprinkler systems typically deliver how many gallons per minute of water?
    1. 10 to 20
    2. 20 to 30
    3. 30 to 36
    4. 40 to 46

     

12. Water mist fire suppression typically uses less water than sprinklers. How much less?
    1. Up to 10% less
    2. Up to 30% less
    3. Up to 60% less
    4. Up to 90% less

     

13. What are the advantages of smaller-sized water droplets from water mist?
    1. Faster evaporation
    2. More surface area for heat transfer
    3. Better oxygen bonding
    4. Both A and B

     

14. Data center fire suppression systems are often configured to be:
    1. Total flood
    2. Localized or machine-specific
    3. Turned on and off through an app
    4. Located outside the building
    5. Both A and B

     

15. Fire suppression systems are effective in modular, micro, and containerized data centers:
    1. True
    2. False
