CompTIA Security+ Question K-13

Which of the following results in datacenters with failed humidity controls? (Select TWO).

A. Excessive EMI
B. Electrostatic charge
C. Improper ventilation
D. Condensation
E. Irregular temperature

Answer: B,D

Explanation:
Humidity control prevents the buildup of static electricity in the environment. If the humidity drops much below 50 percent, electronic components are extremely vulnerable to damage from electrostatic shock. Most environmental systems also regulate humidity; however, a malfunctioning system can cause the humidity to be almost entirely extracted from a room. Make sure that environmental systems are regularly serviced. Electrostatic damage can occur when humidity levels get too low. Condensation is a direct result from failed humidity levels.
