Which of the following controls would BEST prevent accidental system shutdown from the console
or operations area?

A.
Redundant power supplies

B.
Protective switch covers

C.
Shutdown alarms

D.
Biometric readers

Explanation:

Protective switch covers would reduce the possibility of an individual accidentally pressing the
power button on a device, thereby turning off the device. Redundant power supplies would not
prevent an individual from powering down a device. Shutdown alarms would be after the fact.
Biometric readers would be used to control access to the systems.
