What characterizes the effect of high humidity levels in the data center?

Question

Options

• AHigh humidity causes long term corrosion damage to data center equipment.
• BThe extent of corrosion damage depends upon average ambient temperature.
• CThe extent of corrosion damage depends upon the dry airflow pattern in the data center.
• DHigh humidity causes immediate corrosion damage to equipment within the data center.

• A
  81% (21)
• B
  4% (1)
• C
  4% (1)
• D
  12% (3)

Explanation

High humidity introduces persistent moisture into the data center environment, which gradually promotes oxidation and electrochemical corrosion on metal components, circuit boards, and connectors over time - making A correct. Option D is wrong because corrosion is a slow electrochemical process; moisture does not destroy equipment the moment it contacts surfaces, it degrades them progressively. Option B is incorrect because the corrosion risk from humidity is driven by moisture concentration in the air, not by ambient temperature, which is a separate environmental variable. Option C is wrong because dry airflow patterns address cooling and particulate distribution, not the moisture-driven corrosion mechanism. Memory tip: Think of humidity damage like rust on outdoor metal - it builds up slowly over months or years, not instantly, which is exactly why maintaining humidity within recommended ranges (typically 40-60% RH) is a long-term equipment preservation strategy.
