• Question 71:

  Which one of the following is an Objective of Data Center Fire Protection?

  A. Information

  B. Representation

  C. Depression

  D. Suppression

  Correct Answer: D

  The objective of data center fire protection is to suppress or extinguish a fire before it can cause significant damage to the equipment, personnel, or business continuity. Fire suppression systems are designed to reduce the heat, oxygen, or fuel elements of the fire triangle, and to limit the spread of fire and smoke. Fire suppression systems can be classified into two types: water-based and gas-based. Water-based systems include sprinklers, mist, and water spray systems, which use water as the extinguishing agent. Gas-based systems include inert gas, halocarbon, and clean agent systems, which use gases or chemicals as the extinguishing agent. The choice of fire suppression system depends on several factors, such as the fire risk, the type of fuel, the environmental impact, the reliability, the cost, and the compatibility with the data center equipment and operations.

• Question 72:

  Which type of Humidifier suspends quartz lamps over an open pool of water?

  A. Infrared Humidifiers

  B. Water Canister Humidifier

  C. Steam Canister Humidifier

  D. Ultrasonic Humidifier

  Correct Answer: A

  Infrared humidifiers are a type of humidifier that use quartz lamps to heat water in an open pool and evaporate it into the air. They are energy-intensive and require frequent maintenance and cleaning. They are not recommended for data centers, as they can introduce contaminants and bacteria into the air, and increase the risk of fire and electrical hazards.

• Question 73:

  Which Class of Fires involves ordinary combustible materials such as paper, wood and cloth?

  A. Class A

  B. Class B

  C. Class D

  D. Class K

  Correct Answer: A

  According to the CDCP Preparation Guide, Class A fires involve ordinary combustible materials such as paper, wood and cloth. These materials leave behind ash or embers when they burn. Class A fires can be extinguished by water or other cooling agents that reduce the temperature of the fuel below its ignition point.
