A technician is investigating intermittent switch degradation. The issue only seems to occur when the building’s
roof air conditioning system runs. Which of the following would reduce the connectivity issues?
A.
Adding a heat deflector
B.
Redundant HVAC systems
C.
Shielding
D.
Add a wireless network
Explanation:
EMI can cause circuit overload, spikes, or even electrical component failure. In the question it is mentioned that
switch degradation occurs when the building’s roof air-conditioning system is also running. All
electromechanical systems emanate EMI. Thus, you could alleviate the problem using EMI shielding.
