SK0-004 · Question #472
Which of the following security measures would be MOST effective in a datacenter that experiences frequent power surges and spikes? (Choose two.)
The correct answer is A. Security guards D. Access lists. When power surges frequently occur, electronic access systems become unreliable, making non-electronic controls like security guards and access lists the most resilient physical security measures.

Why each option
When power surges frequently occur, electronic access systems become unreliable, making non-electronic controls like security guards and access lists the most resilient physical security measures.
Security guards are human-based physical controls that remain fully operational during power surges because they do not depend on electrical systems, ensuring consistent enforcement of access policy.
Numeric keypads are powered electronic devices that can malfunction, lock up, or be damaged by power surges, making them unreliable in this environment.
Biometric readers depend on powered sensors and processing hardware that are vulnerable to voltage instability, and a power surge can render them inoperable or cause false readings.
Access lists are paper-based or manually maintained records of authorized personnel that require no electrical power to consult or enforce, making them reliable when electronic systems are disrupted.
RFID chip readers require stable electrical power to communicate with chips and authenticate users, and can be disrupted or permanently damaged by power surges.
