Which of the following is the best alternative to control the temperature in a data center?

Question

Options

• ARedundant rack fans
• BRedundant CO2 units
• CRedundant CPU fans
• DRedundant AC units

• B
  9% (2)
• C
  5% (1)
• D
  86% (19)

Explanation

Redundant AC (air conditioning) units are the industry-standard solution for controlling temperature in a data center because they provide dedicated, scalable, and precise cooling for the entire facility - not just individual components. Rack fans (A) only circulate air within a single rack and cannot regulate ambient temperature across the data center. CO2 units (B) are used in fire suppression systems, not temperature control. CPU fans (C) cool individual processors and have no impact on room-level temperature management.

Memory tip: Think "AC = Air Conditioning = the whole room." Data centers need building-level thermal management, and redundancy ensures cooling continues if one unit fails - a single point of failure in cooling can destroy an entire data center within minutes.
