Answer: D


Which of the following protection devices is used for spot protection within a few inches of the object, rather than for overall room security monitoring?
A. Wave pattern motion detectors
B. Capacitance detectors
C. Field-powered devices
D. Audio detectors

Answer: B
Explanation: "Capacitance. Capacitance detectors monitor an electrical field surrounding the object being monitored. They are used for spot protection within a few inches of the object, rather than for overall room security monitoring used by wave detectors. Penetration of this field changes the electrical capacitance of the field enough to generate an alarm" - The CISSP® Prep Guide: Gold Edition by Wiley Publishing Page 480.

D. Are visitors to sensitive areas signed in and escorted?

Answer: B


The concentric circle approach is used to
A. Evaluate environmental threats.
B. Assess the physical security facility,
C. Assess the communications network security.
D. Develop a personnel security program.

Answer: B
Explanation: The original answer for this question was C (assess the communications network security) however I think the concentric circle is defining what in the krutz book is know as the security perimeter. To this end this is a reference "A circular security perimeter that is under the access control defines the area or zone to be protected. Preventive/physical controls include fences, badges, multiple doors (man-traps that consists of two doors physically separated so that an individual can be 'trapped' in the space between the doors after entering one of the doors), magnetic card entry systems, biometrics (for identification), guards, dogs, environmental control systems (temperature, humidity, and so forth), and building and access area layout." -Ronald Krutz The CISSP PREP Guide (gold edition) pg 13
"Pass Any Exam. Any Time." - 318
This is a standard concentric circle model shown in Figure 1 . If you've never seen this, you haven't had a security lecture. On the outside is our perimeter. We are fortunate to have some defenses on our base. Although some bases don't have people guarding the gates and checking IDs any longer, there's still the perception that it's tougher to commit a crime on a Naval base than it would be at GM. The point is: How much control do we have over fencing and guards? The answer: Not much. The next circle, the red circle, contains your internal access controls. For our purposes, the heart of the red circle is the computer. That's what I want to zero in on. The internal controls are the things you can do to keep people out of your PCs and off your network.

The basic Electronic Access Control (EAC) components required for access doors are an electromagnetic lock,
A. A credential reader, and a door closed sensor.
B. A card reader, and a door open sensor.
C. A biometric reader, and a door open sensor.
D. A card reader, and door motion detector.

Answer: A
Explanation: We have not been able to find any reference to this question really. So we are going with “A credential reader, and a door closed sensor”.
"In addition to smart and dumb cards, proximity readers can be used to control physical access. A proximity reader can be passive device, a field-powered device, or a transponder." - Ed Tittle CISSP Study Guide (sybex) pg 650

What fencing height is likely to stop a determined intruder?
A. 3’ to 4’ high
B. 6’ to 7’ high
C. 8’ high and above with strands of barbed wire
D. No fence can stop a determined intruder

A controlled light fixture mounted on a 5-meter pole can illuminate an area 30 meter in diameter.
For security lighting purposes, what would be the proper distance between fixtures?
A. 25 meters
B. 30 meters
C. 35 meters
D. 40 meters

Answer: A
Explanation: The answer should be 25 meters: If a lamp provides a 30 foot illumination, the lamps should be placed less than 30 feet apart to provide an overlap. A 30 meter coverage area mean the next light should be less than 30 meters away, and the only answer that fits is 25 meters. Chapter 6, page 459 of Shon Harris CISSP 5th edition book.
