Certified Cloud Security Professional (CCSP) — Question 274

Which of the following is the optimal humidity level for a data center, per the guidelines established by the America Society of Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE)?

Answer options

• A. 30-50 percent relative humidity
• B. 50-75 percent relative humidity
• C. 20-40 percent relative humidity
• D. 40-60 percent relative humidity

Correct answer: D

Explanation

The optimal humidity level for a data center, as indicated by ASHRAE, is between 40-60 percent relative humidity, which helps prevent both static electricity and condensation. Options A and C fall outside the recommended range, making them less ideal, while option B exceeds the upper limit, potentially leading to moisture issues.
