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.
But using protective switch covers will not help in case of shut down the device remotely from operations area, or what meant hear by operations area?
