What is the primary risk associated with using motion detectors to automatically unlock a data center door when a person is attempting to exit?
A. The motion detector may not sense some employees based upon their physical characteristics.
B. The motion detector may not work during a power failure.
C. An employee may exit the facility with unauthorized materials.
D. An intruder may attempt to trigger the motion detector from the outside to gain entry.
Correct Answer: D
The primary risk associated with automated exit motion detectors is that an intruder outside the facility may be able to gain access by triggering the motion detector. For example, if it is possible to slide a piece of paper under the door, it may be possible to forcefully push the paper through so it flies up in the air and triggers the detector.
