ANSWERS 2026 - 2027
Recommended - ANSWERS-The conditions are narrower, and represent
the target conditions at which the hardware environment should be
maintained for optimal reliability and performance.
Allowable Specifications - ANSWERS-Specifications are generally
quite varied and define the maximum limit that the hardware should
never exceed. Example, may accommodate warm temperatures, but that
may not be best for the hardware to achieve the most reliable operation.
Humidity and temperature - ANSWERS-What two metrics is the HVAC
system trying to control in a facility?
Conductive anodic filament (CAF) Formation - ANSWERS-is a well-
studied phenomenon driven by chemical, humidity, voltage, and
mechanical means.
Letent heat of fusion - ANSWERS-The amount of heat to melt ice.

EXAM QUESTIONS AND
ANSWERS 2026 - 2027
Cold Liquid HVAC - ANSWERS-HVAC system is helpful in hot desert
climates--taking air that needs to be cooled into the HVAC unit intake.
The intake air goes through stages before it is sent to the data center.
Downflow Method - ANSWERS-The most common airflow path used
by CRAC units, a combination of return air entering the top of the unit
and supply air being discharged from the bottom of the unit.
Discharged Air - ANSWERS-air typically empties into a raised floor
plenum below the electronic equipment racks. The air supply pressurizes
the raised floor plenum and then exits through cold tiles, which are
perforated floor tiles located next to the rack-mounted equipment.
Up-flow Method - ANSWERS-The cold supply air from the unit can be
discharged through the bottom, the front, or through the top. The warmer
return air can also be configured to enter the CRAC unit from the front,
the rear, or the top
