2026 QUESTIONS WITH ANSWERS FULL
SOLUTION.
⫸ Up-flow Method. Answer- 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
⫸ Direct Expansion. Answer- What is the most common air
conditioning system used in HVAC?
⫸ Infrastructure right-sizing. Answer- Matches growth with the capacity
to optimize the investment.
⫸ N+2. Answer- If a HVAC system is built where there is one main
system and two backup systems it would fall into which redundancy
class?
⫸ Power usage effectiveness (PUE). Answer- The ratio of the total
amount of power that might be used by the headend or hub, to the power
required for the critical or IT equipment--includes power used for
lighting, cooling systems, power distribution.
, ⫸ PUE. Answer- total facility power used/total consumed power by IT
equipment
⫸ Carbon Usage Effectiveness (CUE). Answer- a ratio of the total
carbon emissions due to the total energy consumption of the data center
compared to the energy consumption of the data center's servers and IT
equipment.
⫸ Water Usage Effectiveness (WUE). Answer- a ratio of the annual
water usage to how much energy is being consumed by the IT equipment
and servers, and is expressed in liters/ kilowatt-hour (L/kWh).
⫸ 2 AWG. Answer- gauge of wire should be used inside the facility to
bound the equipment to the ground
⫸ National Fire Protection Association. Answer- The organization
OSHA ask for help to create workplace electrical safety standards
⫸ Overage. Answer- can be the result of long-term problems that create
swells, or, overvoltage can be thought of as an extended swell.
Overvoltages are also common in areas where supply transformer tap
settings are set incorrectly and loads were reduced.
