Which cooling architecture attempts to eliminate hot spots within the data center by utilizing large volumes of air mixing throughout the space?

  1. Row
  2. Rack
  3. Room
  4. Ceiling

Answer(s): C



In order to determine the exact level of redundancy available in the cooling system, which cooling architecture would require CFD analyses of every combination of system failures within the data center?

  1. Row
  2. Rack
  3. Room
  4. Ceiling

Answer(s): C



Which statement best describes how a row-oriented cooling architecture optimizes the operational efficiency within the data center?

  1. Row-oriented architecture allows cooling capacity to be matched to the heat load within each zone.
  2. Row-oriented architecture requires two cooling units per enclosure, creating a desirable oversizing scenario.
  3. Row-oriented architecture cools all rows of the data center while generating additional conditioned air for the adjacent office areas.
  4. Row-oriented architecture requires large volume of air mixing to reduce the return air temperature, driving up cooling system capacity.

Answer(s): A



What is the load per rack where the room cooling architecture starts to become impractical?

  1. 1 kW
  2. 3 kW
  3. 7 kW
  4. 10 kW

Answer(s): B



What is an advantage of hot aisle/cold aisle rack configuration?

  1. It prevents hot exhaust air from leaving the cold aisle.
  2. It prevents cold air from being drawn into the IT equipment intakes.
  3. It prevents exhaust air of one rack from being in the intake.
  4. It prevents hot exhaust air from reaching the computer room cooling units.

Answer(s): C
