What is an advantage of hot aisle/cold aisle rack configuration?
A. It prevents hot exhaust air from leaving the cold aisle.
B. It prevents cold air from being drawn into the IT equipment intakes.
C. It prevents exhaust air of one rack from being in the intake.
D. It prevents hot exhaust air from reaching the computer room cooling units.
Which statement best describes how a row-oriented cooling architecture optimizes the operational efficiency within the data center?
A. Row-oriented architecture allows cooling capacity to be matched to the heat load within each zone.
B. Row-oriented architecture requires two cooling units per enclosure, creating a desirable oversizing scenario.
C. Row-oriented architecture cools all rows of the data center while generating additional conditioned air for the adjacent office areas.
D. Row-oriented architecture requires large volume of air mixing to reduce the return air temperature, driving up cooling system capacity.
Which cooling architecture has the shortest air flow paths between the cooling unit and the IT equipment?
A. Row
B. Rack
C. Room
D. Building
Which cooling architecture attempts to eliminate hot spots within the data center by utilizing large volumes of air mixing throughout the space?
A. Row
B. Rack
C. Room
D. Ceiling
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?

Which is an example of a rack-oriented cooling architecture?
A. A cooling unit is located in the ceiling plenum to cool the data center racks.
B. A cooling unit is located within the rack itself to cool the contents of that rack.
C. A cooling unit utilizes perforated raised floor tiles to deliver cool air to the rack.
D. A cooling unit is located along the perimeter wall of the data center to cool a specific zone of racks.
What are three benefits of rack-oriented cooling architecture? (Choose three.)
