Right, but the first rule of security is physical. That's why it's correct. You would detect a vehicle driving up to a Bollard. Motion Senors are similar to IDS's. Important, but physical is the more important part of the question.
But the question is "Which of the following would detect intrusions at the perimeter of an airport?". It's asking what object would detect. Bollards can't detect anything, they're a cement or metal rod in the ground.
Not at all. None of us KNOW what the right answer is according to CompTIA, they don't tell you which questions you get right or wrong. That's why there are discussions.
Most likely the wrong answers are identified by the first vote, or perhaps by the person who provided the question. Or as some speculate, they are wrong on purpose so that CompTIA can't say that this site is providing all the correct answers to their actual exam questions.
Personally, I would rather they left the "correct answer" off altogether and just let our votes dictate the "right" answer. I find that I research the answers myself if the community seems split, thus I learn more.
amen to that. they definitely do this on purpose so we discuss. If they were all correct, would we even have to? It's genius. They make it fun to learn!
C. Motion sensors
Motion sensors would be the most appropriate choice for detecting intrusions at the perimeter of an airport. Motion sensors can detect movement and trigger an alarm or alert when unauthorized individuals or objects breach the secured area. This can be an effective security measure for monitoring the perimeter and identifying potential security threats.
While other options such as signage (A), fencing (B), lighting (D), and bollards (E) contribute to the overall physical security of the perimeter, they are not designed specifically for detecting intrusions. Motion sensors provide an active detection mechanism by sensing movement, making them a suitable choice for perimeter security.
We got folks talking about PIDS and fiber optics as they relate to detection systems on a fence, light, or bollard. Are ya serious? It's a motion sensor. Number one synonym for sensor? Detector! Key word is perimeter? Okay. Can't have a motion sensing light on top of a bollard next to a fence with signs on it without a motion sensor. Motion sensor. Motion sensor.
I Thought at first motion sensor then i read the question " airport perimeter" you can not install motion sensors in an area as vast as airport perimeter thats why you see ballards all around the airport buildings just google airport bollards there are 2 types one gated that let cars in and one static preventing entry non of those are detective but bollards are the only method airport use on perimeter
I may be kind of new at this, but its obviously C. I saw someone else say this answer is wrong on purpose, and I believe that. I've seen several that were SUPER obviously wrong. :)
The correct answer for detecting intrusions at the perimeter of an airport is:
C. Motion sensors
Motion sensors are specifically designed to detect movement, and they are commonly used as part of an intrusion detection system to monitor and alert security personnel to any unauthorized activity along the perimeter. While other options like fencing and lighting play essential roles in perimeter security, motion sensors are the primary choice for actively detecting intrusions.
