TEMPEST deals with which of the following forms of environmental control?
a. HVAC
b. EMI shielding
c. Humidity
d. Cold-aisle
Answer: B
TEMPEST protections involve the hardening of equipment against EMI broadcast and sensitivity. Answers A and C are incorrect because HVAC controls include temperature and humidity management techniques to manage evolved heat in the data center and to minimize static charge buildup. Answer D is incorrect because hot-aisle/cold-aisle schemes provide thermal management for data centers by grouping air intakes on cold aisles and air exhausts on designated hot aisles, making HVAC more effective.
