Exam CISSP topic 1 question 341 discussion

Gaurds are most effective

Agree with A

I almost went with D but its asking for a CORRECTIVE control so this means the other controls already failed. The other controls are detective, preventive, and deterrents

I dont know if the questions are really tricky, but if you read the question, minimize the effects of of physical intrusion (does it mean the physical intrusions already happened and based on the corrective control we are finding the best deterrent control moving further?) in this case the answer would be A based on the CISSP training. in other words, the most effective corrective control is to find a preventive control.

A. Rapid response by guards or police to apprehend a possible intruder.........A. is the only corrective control among the options provided. The rest are deterrent controls.

A appears to be the only corrective control. "Corrective controls are designed to respond to errors or events in order to take action to minimize risk of future occurrence." https://sharedassessments.org/glossary/corrective-control/ Police and guards responding is the corrective control (which means a response) Lights and sounds appear to be detective and deterrent: https://blog.eduonix.com/networking-and-security/learn-different-types-security-controls-cissp/

from the given answers, only guards are corrective controls. B and D are deterrent controls.

D, it say Activating the bring lighting

Key point here is to minimize the effects of the intrusion

Only "A" will give you a CORRECTIVE control. The other options are mostly deterrents.

D is correct answer. Bright light is most effective corrective action
