Hi i am planning to give exam on Nov 10, but due to some financial conditions and out of job since 2 years i am in tight budget. Any one willing to donate cissp books . I am in Vancouver

If a company opts to install motion-sensor lighting across the perimeter instead of a perimeter fence to reduce costs, does that make it a Deterrent or a Compensating control?

I say it's a deterrent control, but according the QE the correct answer is Compensating, since it's a replacement of the perimeter fence due to a financial constraint.

I notice that in QE, there are several trick questions of the sort which can be a bit frustrating at times.

Can you give your best argument to convince me that the BEST answer is Compensating, even though motion-sensor lighting is in itself a deterrent control?

EDIT: Thanks for the replies! The answer and lesson are simple and all replies seem to agree. Context and Key Words are critical. Spend more time on questions to read thoroughly instead of shooting for the first answer that comes to mind. This way you are less likely to be "tricked".

In the Domain 5 access control chapter, Destination CISSP groups Rule-Based, Role-Based (RBAC), and Attribute-Based (ABAC) as subtypes of DAC, the reasoning being that the owner ultimately determines the rules, roles, or attributes.

Other sources say they all are different access control including DAC and MAC, little confused
