CompTIA Security Plus Mock Test Q368

A datacenter requires that staff be able to identify whether or not items have been removed from the facility. Which of the following controls will allow the organization to provide automated notification of item removal?

A. CCTV
B. Environmental monitoring
C. RFID
D. EMI shielding

Correct Answer: C
Section: Compliance and Operational Security

Explanation:
RFID is radio frequency identification that works with readers that work with 13.56 MHz smart cards and 125 kHz proximity cards and can open turnstiles, gates, and any other physical security safeguards once the signal is read. Fitting out the equipment with RFID will allow you to provide automated notification of item removal in the event of any of the equipped items is taken off the premises.

Incorrect Answers:
A: CCTV will record events, but will not automatically notify you of item removal.
B: Environmental monitoring concerns events such as water, flood, humidity, fire, etc. types of threats and not theft as in the case of item removal.
D: EMI shielding refers to the process of preventing electronic emissions from your computer systems from being used to gather intelligence and preventing outside electronic emissions from disrupting you information-processing abilities. It is not designed to automatically notify you of events when items are removed.
