Which NCPI component protects the data center during long duration outages (several hours to days)?
A. Generator
B. Static UPS
C. Flywheel UPS
D. Automatic transfer switch
Why are frequency variations a small concern for data center managers?
A. Frequency variation helps server performance.
B. Computer power supplies are frequency tolerant.
C. Frequency variation is strictly a theoretical problem.
D. Frequency variation occurs during sag conditions, which the UPS resolves.
Undervoltage is a more technically accurate term to describe what event?
A. Blackout
B. Brownout
C. Power drought
D. Power suppression
Which can cause a swell or surge to occur in the data center's electrical system?
A. UPS failure
B. CRAC unit startup
C. Transformer failure

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.
How do non-insulated water pipes impact humidity in the data center?
A. They can increase the humidity in the data center.
B. They can decrease the humidity in the data center.
C. They do not affect the overall humidity of the data center.
D. The affect they have on humidity depends on whether the pipes are copper or steel.
Which rack / enclosure would be used for limited space with just one or two pieces of small equipment?
A. Seismic enclosure
B. Four post open frame
C. Wall-mount enclosure
D. Free-standing enclosure
Seismic enclosures are designed to protect installed equipment from what hazards?
A. Earthquakes
B. Liquids
C. Dusty environments
D. Fire or excessive heat
Where should applications that use side-to-side cooling or high cable densities be installed?
A. Seismic enclosure
B. 600 mm enclosures
C. 750 mm enclosures
D. Wall-mount enclosures
