CompTIA Security+ Question B-97

Which of the following is an attack vector that can cause extensive physical damage to a datacenter without physical access?

A. CCTV system access
B. Dial-up access
C. Changing environmental controls
D. Ping of death

Answer: C

Explanation:
Environmental systems include heating, air conditioning, humidity control, fire suppression, and power systems. All of these functions are critical to a well-designed physical plant. A computer room will typically require full-time environmental control. Changing any of these controls (when it was set to its optimum values) will result in damage.
